We are happy to answer any questions you may have. Depending on the outcome of those exercises, the officer will probably arrest you because those exercises are designed to cause a person to fail. Sober people fail sobriety tests every day. Once under arrest, the officer will ask you to blow your breath into an Intoxilyzer, which is more commonly known as a breathalyzer. If the resulting breath alcohol concentration (BrAC) is at or above the legal limit, you are per se intoxicated in Texas. The good news is that the prosecution has to prove that you were intoxicated at the time you were DRIVING. The breath test is usually 45 minutes or longer from the time of driving. Breath (BrAC) and blood (BAC) alcohol legal limits in Texas are as follows: Though the latter may be true -- i.e., there's an assumption you are guilty -- it does NOT mean you are in fact legally guilty. In fact, retaining a lawyer who has proven experience in DWI criminal defense and breath tests can be the difference between a DWI conviction and a dismissal of the charge or not guilty verdict. Doug Murphy, reputable DWI criminal defense lawyer in Houston, Texas, not only knows the law, the flaws, and inaccuracies associated with breath testing--Doug has a proven track record and reputation for successfully winning breath and blood test cases at trial. That's something to think about when it comes to your DWI charge and your search for an experienced criminal defense attorney who can help maximize the possibilities that your case will have a successful outcome. Contact Doug Murphy today to discuss the specifics of your case. The machine has only been in use for a very short time in Texas, but other states, like Colorado, Georgia, and NewYork, have been using it for several years. The Intoxilyzer 9000 looks for the presence and amount of alcohol in a breath sample. It uses infrared light to both identify and quantify ethyl alcohol because ethyl alcohol absorbs infrared light in a unique way.

The pattern of absorption is used to identify alcohol, and the amount of absorption is used to quantify alcohol in a breath sample.First, a breathalyzer doesn't measure the amount of alcohol in either the brain or the blood. Breathalyzers measure alcohol that has evaporated from the blood system and then travels into the person's airway. But the machine (and police officers) assumes that the amount of alcohol in the breath is the same as that in the blood. This is an incorrect assumption. Though the relationship exists, it varies according to multiple factors. The warmer your body temperature, the warmer alcohol diffuses from blood into your lungs. The warmer your body temperature, the higher the BAC reading will be. Compounding this factor is the fact that our temperatures vary by degrees. The breathalyzer assumes your temperature is 34 C. Just one degree above 34 C is enough to increase a person's BAC by 7. If you are a shallow breather, then your BAC results could be as high as 20 than the true BAC level. Breathing is not controlled, and there is no method to determine how a person breathed at the moment you blew breath into the breathalyzer. All breathalyzers used in any state of the United States, including Texas, proportions the relationship between breath and blood at 2100 to 1. Thus, for every part alcohol on the breath, there is 2100 times greater alcohol in the blood. The idea is simple using this ratio: if 2100 cubic centimeters of deep lung air was analyzed for alcohol, the result would be equal to the amount of alcohol in a milliliter of blood. Research has identified that this ratio is misleading, and something closer to the truth is a range rather than a strict ratio. This ratio range can be anything from 990 cubic centimeters of deep lung air to 3005 cubic centimeters of deep lung air representing 1 milliliter of blood.
https://artoftheark.com/images/breast-pump-manual-or-automatic.pdf
If your ratio is below 2100, which can very realistically be the case, then the BAC is artificially high and your arrest could have been unwarranted. Your breath to blood partition ratio will vary from your mother's, your brother's, your friend's, and it can even change for you over time. We all absorb alcohol at different rates. In fact, it can take anywhere between one and five hours to absorb alcohol fully if you consumed alcohol on a full stomach, and between one and two hours if you consumed alcohol on an empty stomach. Breath tests, however, assume that you are in the post-absorptive phase. Without knowing the absorption phase, it is nearly impossible to know if the BAC level is indicative of your actual state. The machines are designed only to provide an estimate, not a certainty, but officers use it as though the result is definitive. Females generally score higher on average more so than males, and the latter is in part the reason. In fact, the machine assumes each person blowing into it is of the same sex and average weight, and due to this assumption, results can vary, which also means it can vary on the side of error that is to your legal, emotional, financial detriment. Specifically, if you have diabetes, heartburn, liver disease, gum disease, heart disease, fever, or, among other things, are on certain medications. Some diets even affect the test, specifically the ketogenic diet, which can have the same effect on the body as diabetes. If strong or close enough, radio frequency from a cell phone or a peace officer's radio can cause the instrument to malfunction. The 9000 is equipped with an automatic detection device, but it is not fully accurate. If interference happens, the BAC reading will be affected and the results could be suppressed. The Intoxilyzer 9000 allows for a variance of.20 between two breaths. As such, law enforcement can give you two tests, and the results may be within.02 of each other. This is a problem.
Consider, if your first test was.08, and the second test resulted in a BAC at either.06 or.10, one reading establishes you below the legal limit while the other reading puts you well above the legal limit. Is this acceptable? According to Texas law and practice, it is.Breathalyzers are supposed to be maintained regularly, and if not, they become faulty. There are guidelines that advise how to maintain breathalyzers, including routine maintenance. There's a lot of things going on at a police station, and maintenance is often overlooked or neglected. When this happens, faulty results happen. If maintenance is not upkept, its accurate functioning capabilities are reduced. Doug Murphy is the lawyer who can help you get your case dismissed. Of course, all cases are different with their unique facts and circumstances, but Doug Murphy is thoroughly knowledgeable of the faults and failures of breath tests, and he exposes these faults and failures strategically during your defense. As always, bad breath tests come down to the poor administration of the Intoxilyzer. Below are some things to keep in mind if you are requested to give a breath sample: A clean, unused mouthpiece must be used each time. If not, he was not permitted to administer the test. The standard range is.075 to.085; if it was not within this range, then that is grounds to suppress the results. We have decades of proven experience and a reputation earned in the courtroom for successful results. Attorney Doug Murphy is a Board-certified criminal defense lawyer and a Board-certified DWI lawyer who not only fights on behalf of his clients but constantly gives back to the legal community to teach other attorneys how to do the same.

Texas law allows the police officer to arrest you if you fail the test. These tests are not accurate and some may believe they are actually designed to make a person fail, even sober, this test is difficult to pass. If this test shows your blood alcohol concentration is above or even at the legal limit, you will be considered intoxicated under Texas law. You will want a strong legal defense to protect your rights and future against this charge. Being arrested due to the results of the DWI breath test does not mean you are automatically going to be found guilty. A strong legal defense can lead to a dismissal or reduction of these charges. This test is done by having you blow into a breathalyzer, or breath testing machine. These machines are handheld devices the officer usually carries with them and can be used at the site of your stop. There are also desktop versions of these devices. Many times, you will be asked to perform the PBT on the site, and are then required to repeat the test at the police station using the desktop model. Remember, you do not have to take the PBT test on the site; however, this action does give the officer probable cause to arrest you. In Texas, the legal limits for breath and blood are: The prosecution is going to have to prove you were driving while intoxicated as there are numerous inaccuracies and flaws involved with breath testing equipment. This machine has only been in use for a short time in Texas, even though other states have been using it longer. Just as the older models, the Intoxilyzer 9000 is based on the theory of infrared spectrometry. It will check for the presence of alcohol in your breath. By using infrared light, it will identify and verify the quantity of ethyl alcohol in your breath. Analytical results in grams are provided by the Intoxilyzer 9000 per 210 liters of breath which are required by law under Texas Penal Code 49.01(1)(a).
By performing the breath test, police officers and the breathalyzer assume the amount of alcohol registering is the same in your blood as it is in your breath. The truth is several factors make this relationship inconsistent. How you breathe into the breathalyzer impacts the BAC reading. When your breath is shallow, the BAC results could read as high as 20 more than a true BAC level. There is no accurate test for determining how you were breathing at the time the test was administered. It has been determined that the ratio is misleading and something closer to a range rather than a strict ratio. In reality, if your ratio is below 2100, which is a very realistic result, then your arrest is unwarranted. Breath to blood ratio can vary from brother to friend, you to your mother’s, or you to one of your siblings. This ratio can even change over time. If your body temperature is warm, the alcohol will diffuse from your blood into your lungs. The warmer you are at the time of the test, the higher your BAC reading will be. This factor plus the fact that everyone has a different body temperature by a couple of degrees affects how the test should be read. The breathalyzer is designed to assume your body temp is 34c; therefore, one degree above the 34c will increase your BAC reading by 7. Devices are only designed to give one an estimate, and not a certainty, which is not what the police officer arresting you will take into account. The testing is done to determine your blood alcohol content (BAC) or if you are under the influence of illegal drugs. The police officer has to have probable cause in order to stop you, and if during that stop suspects you are under the influence can then request you submit to one of two tests. The officer may be asking you to consent to the test to establish a cause for your arrest. Once you give consent, you do have the right to have a blood test performed by a physician of your choice within two hours of the police test.
This test will be at your expense. Under Texas law, you are required to take this test. Refusal of the mandatory breath test can result in facing harsher DWI penalties. If you strongly feel that legal counsel would be to your advantage before testing, you can refuse and call your DWI attorney. Speak with them over the phone and explain your situation. Your attorney will advise whether you should wait for their arrival on the scene, or if you should go ahead with the breath testing. If the warrant is given, you then have no legal right to refuse a test. The police have the authority to hold you down in order to draw blood, and if this action is necessary, you could face additional charges. These laws are fall under the No Refusal Weekend Program enforced in many states across the country by both state and federal governments as a push in handling DUI and DWI cases. There are certain circumstances where you are not allowed to refuse BAC testing. These circumstances include: These consequences could include jail time, losing your license, and a fine. You must also be advised of your rights which do not include having an attorney present prior to the testing and refusing to allow the test to be administered will be held against you in court. They may claim the presence of a controlled substance, a drug, or alcohol and another substance may have caused you to be in a toxicity state. If they are able to prove you exhibited a loss of physical or mental faculties, then they will proceed to a conviction. These results are unreliable depending on the number of drinks you consumed, the type of alcohol you were drinking, whether or not you had any food during the time of drinking, your current weight, and even the time when the test was administered. If you or you know of someone who is facing DWI charges, contact an attorney immediately. Having a conviction on your criminal record for this charge will significantly impact your future.

These devices are designed more for the average male. The breathalyzer assumes everyone who blows into it is at the same average weight and the same sex, which results in the test findings varying. This variance in results also means it could be different results depending on your financial detriment, emotional state, and legal situation. Your health when the test was administered plays a large part in how the results will read. Diseases such as diabetes, liver disease, heart disease and conditions such as heartburn, fever, gum disease and other health-related issues can impact how the breathalyzer reads your results. Specific diets such as the ketogenic diet will affect the results as well. This disease can create a false positive or test reading error. The machines are designed to measure the alcohol content in your lungs lining. The lining is reported to provide the most accurate measurement of alcohol content; however, medical professionals disagree with this fact. If you suffer from Gastroesophageal Reflux Disease, alcohol is able to move from your stomach to the back of your throat making your readings on the breathalyzer to register much higher. Even if you do not suffer from this gastroesophageal disease, if you’ve eaten a meal that produces acid reflux such as greasy or spicy foods, then your results on the breath testing will be skewed. These machines do not measure alcohol; they measure the level of a methyl group of chemical compounds which the machine assumes is ethyl alcohol. Infrared breath testers particularly use this form of measurements. The problem this creates with these machines is other chemical compounds could be present in your breath that will cause a false reading with your DWI breath testing. This substance can even create a 0.06 BAC reading on someone who has not even consumed alcohol. Consuming mints, garlic, or onions will not affect the readings of the machine.
These products can mask the odor of alcohol, but will not change the BAC readings. Cell phones and police officer’s radios can also interfere with the performance of this device. The Intoxilyzer 9000 has been equipped with automatic detection, but this function is not completely accurate. Interference can occur which will affect the BAC reading. This malfunction could be used in your defense to have the results from this test suppressed during your trial. Law officials are allowed to give you two tests, and these two tests results can be within.02 of each other, and the Intoxilyzer 9000 allows for a difference of.20 between your two breaths. Texas law states this testing is legal and the results can be used in your prosecution. A strong legal defense can fight these results and is why you need an experienced DWI attorney to defend your rights if you find yourself charged with a DWI in Texas. These machines are intended to receive regular maintenance, or they can produce faulty results. Guidelines are given to law enforcement or any entity using these devices on how to maintain them in order to ensure they receive accurate results from tests. Police officers have a lot going on during a daily routine, and maintenance schedules are not always followed. It could work in your defense if the machine used in your breath testing was not properly cared for. Poor administration can result in poor breath testing and inaccurate readings. There are specific instructions police officers are to follow when performing DWI breath testing on the Intoxilyzer 9000. These steps to watch for if you are asked to provide a breath sample: Waiting 15 minutes is in accordance with the Operator Manual for the Texas Breath Alcohol Program to ensure there is no residual alcohol present. Check that the one you are asked to use has no signs of being used prior to your test. If they are not certified on this machine, they cannot administer the test.

The Department created the Office of the Scientific Director and developed rules governing evidential breath testing. These rules are contained in the Texas Administrative Code Title 37 Chapter 19 and are commonly known as the Texas Breath Alcohol Testing Regulations. All analyses conducted by state, county, and city law enforcement officials are performed in accordance with these regulations, which require the certification of all aspects of breath testing. These breath alcohol analyses are performed in conjunction with various alcohol related criminal offenses and the enforcement of commercial driver license statutes. Duties include certification of 340 breath testing instrument locations and 4,200 breath test operators. The office also provides expert testimony as needed in contested criminal, civil, and administrative breath test cases. Breath alcohol ignition interlock devices (BAIID) require the operator of a motor vehicle to submit a sample of alcohol free breath prior to engaging the ignition. Many courts and probation officers mandate the installation of such devices as a condition of probation for individuals convicted of alcohol related offenses. The Texas Ignition Interlock Device Regulations of Title 37 Chapter 19 Texas Administrative Code govern BAIID activity. In 1972, however, Omicron Systems Corporation introduced a machine using a new method of analysis based on infrared spectrophotometry (also called infrared spectroscopy or, simply, infrared absorption). Omicron’s Model 4011 was faster, easier to use, and more economical and convenient that the Breathalyzer. There was no evidence, however, that the device was any more accurate; in fact, because of greater risk of nonspecific analysis, the machine was determined by many to be less reliable.
Subsequently, CMI introduced a new, state-of-the-art breath-testing device: THE Model 5000. This machine also utilized infrared spectrophotometry in its analysis, but incorporated an internal computer and various supposedly “fail-safe” features. Further, CMI claimed to solve the non-specificity problem by using three separate wavelength band filter (subsequent versions employed five filters). In addition, the Model 5000 incorporated an “interference detector” that would theoretically advise the operator whenever foreign substances such as acetone are present in the breath. And acetaldehyde detectors and radio frequency detectors were available as options. Experience, however, has proven that each of these features is less than reliable in ensuring accurate results. Water, for example, will absorb infrared light whose wavelength is 2.7 microns: when this 2.7-micron light passes through water vapor, its vibrations are absorbed by bonds between the oxygen and hydrogen atoms in the water molecule, causing the atoms to vibrate more strongly and the 2.7- micron energy to disappear. Ethyl alcohol has its hydrogen-oxygen bond vibrations shifted slightly by the nearby presence of carbon-hydrogen bonds. As a result, most of the absorption of light by ethyl alcohol will take place in the band range from 3.380 to 3.398 microns. The Intoxilyzer, then, simply shoots a beam of infrared light through the captured breath sample and measures how much of it is absorbed in that range; the more absorption, the higher the blood-alcohol concentration. This chamber captures the breath sample from the subject being tested. A quartz iodide lamp at one end of the chamber then emits infrared light energy, which is directed through the breath in the chamber by a lens. At the opposite end of the chamber, a second lens focuses the energy leaving the chamber through three rotating filters and onto an energy detector.
The first filter is the internal reference standard, designed to produce light waves at ethyl alcohol’s spectrum by being centered at 3.80 microns. Two filter, at 3.40 and 3.47 microns, are designed to distinguish between alcohol and the commonly encountered interferent acetone. Two more filters have been added to detect acetaldehyde (like acetone, produced in the body) and toluene (a common industrial compound). Properly calibrated, these filters are designed to detect and subtract out from the final reading any interfering substance. This primitive computer compares the amount measured to a “ zero reference point”—the amount of infrared energy reaching the detector when the sample chamber was earlier filled with ambient (room) air. The difference—theoretically the amount of light absorbed by the subject’s breath sample—is then calculated.As mentioned, the Intoxilyzer theoretically detects the presence of acetone (and in later models, acetaldehyde and toluene) on the breath, registers “interferent” on the visual display, and automatically subtracts the acetone from the final reading. Quite simply, extensive tests have shown that the detectors do not always work. Again, law enforcement agencies routinely deny that RFI exists as a problem. And again, tests in the field and in the laboratory have shown that these detectors (which can be desensitized by technicians to avoid constant aborted tests) are not reliable. When mouth alcohol is present, the alcohol content curve reaches a maximum and then declines rapidly due to depletion of the mouth alcohol; this decline is recognized by the machine’s computer, resulting in the message “ invalid sample.” Once again, however, the feature is defective. If the air is contaminated by alcohol vapor, the machine will, theoretically, display “ambient failed” and the printout will state “invalid test check ambient conditions.” As with other “fail-safe” devices on the machines, the efficacy of this new feature is open to question.
The main difference between this and the previous model is that it has non-reactive breath chamber. The chamber of the previous 5000s is nickel-coated and can develop oxide build-up. This oxide in the walls of the chamber can absorb ethanol and water vapor, which can then be released into captured breath samples, giving a falsely high reading. Again, most states have statutory requirements for the regular maintenance of breath-analyzing instruments, as well as for their calibration. Any deviation from these requirements should be noted, particularly any malfunctions of the instrument in the past, any erroneous readings, or any recent periods of time without maintenance or calibration. The Intoxilyzer should have a maintenance log and a calibration log that should indicate any abnormalities. Even if the machine has been maintained and calibrated properly for the past several months, the jury will be interested in knowing that it has had problems in the more distant past—that is, that it is fully capable of malfunctioning. Failure to show at least proper calibration at specified time intervals should preclude use of any test results at trial. Certainly, any significant indications in the records that the machine was functioning improperly should be grounds for exclusion. And in some states, the Intoxilyzer must have received a “certificate of inspection” within a specified period of time prior to the administration of the test in question. In Alpert, Keiser, and Syzmanski, “Theory and Practice of Infrared Spectroscopy,” a study is reported in which laboratory spectroscopic tests, considered more reliable than spectroscopic tests conducted by law enforcement in the field, showed instrument-to-instrument variations of up to 20 percent of the measured results. The technical reason for this lack of specificity is that the Intoxilyzer is not designed to detect the molecule of ethyl alcohol (ethanol), but rather only a part of that molecule, the methyl group.
