Health History Medical Examiner Comments Overview At a minimum, your comments should include:. Include a copy of any supplementary medical reports obtained to complete the health history. Page 32 of 260 Vision the Medical Examiner completes section 3: Figure 7 Medical Examination Report Form: Vision Vision Medical Examiner Instructions To meet the Federal vision standard, the driver must meet the qualification requirements for vision with both eyes. Use of contact lenses when one lens corrects distant visual acuity and the other lens corrects near visual acuity. Specialist Vision Certification the vision testing and certification may be completed by an ophthalmologist or optometrist. When the vision test is done by an ophthalmologist or optometrist, that provider must fill in the date, name, telephone number, license number, and State of issue, and sign the examination form. Additionally, ensure that any attached specialist report includes all required examination and provider information listed on the Medical Examination Report form. Hearing the Medical Examiner completes section 4: Figure 8 Medical Examination Report Form: Hearing Hearing Medical Examiner Instructions To meet the Federal hearing standard, the driver must successfully complete one hearing test with one ear. If the driver uses a hearing aid while testing, mark the ?Check if hearing aid used for tests? box. Forced whisper test Record the distance, in feet, at which a whispered voice is first heard. Hearing Hearing Test Example In the example above, the examiner has documented the test results for both hearing tests. The forced whisper test was administered first, and hearing measured by the test failed to meet the minimum five feet requirement in both ears. Therefore, the medical examiner also administered an audiometric test, resulting in:. This three-month certificate is a one-time issuance for the recertification period and is not intended to mean once in the driver?s lifetime. The medical examiner may use his/her clinical expertise and results of the individual driver examination to determine the length of time between recertification examinations.

The paragraphs that follow constitute a brief review of how the principles used in designing equipment for the spacecraft environment can be beneficial for Earth-based settings blood pressure 34 year old male purchase discount coumadin line. That discussion is followed by descriptions of some of the many benefits accrued in the development of imaging arrhythmia greenville sc order coumadin 2mg overnight delivery, communications wide pulse pressure icd 9 code discount coumadin master card, and robotics technologies; materials science; and biotechnology. Next is a brief section on potential commonalities between aging and space flight exposure in terms of bone loss and postural control. Finally, the conclusion underscores the need to continue enhancing the exchange of emerging technologies between space programs and commercial industries. Principles for Designing Analytical Equipment for Use in Space: an Overview Equipment designed for use aboard spacecraft must meet strict requirements in terms of size, weight, volume, power, ease of use, and reliability in addition to being able to function without the influence of gravity (Fig. Although few devices meant for operation on Earth were designed to operate independently of gravity, the other constraints on spacecraft hardware, especially portability, ease of operation, and ease of interpreting results, have led to the development of equipment that expands some capability in Earth settings as well as in space. Moreover, automation, the goal of which for space activities is to minimize the need for intervention by busy crews, also can reduce the need for labor-intensive, time-consuming procedures on Earth, and can extend clinical capability far beyond traditional service points such as hospitals or laboratories. Many research tools for space flight applications began as off-the-shelf equipment that was modified to reduce the size of the component systems. A prototype clinical chemistry analyzer, for example, evolved from a large stand alone device to a small bench-top unit, and from there to a device the size of a toaster. Another example is a tiny ear oximeter-transducer, developed at Ames Research Center, to measure blood oxygen saturation, blood pressure, 1 pulse rate, and pulse pressure during space flight. Other aspects of the spacecraft environment aside from size can drive the development of entirely new analytical techniques. For example, when the need for measuring blood electrolytes during space flight first became apparent in the early 1970s, the analytical methods of that time required the use of flammable gases. Since flammable materials are prohibited aboard spacecraft, another approach was required, and new analytical instruments were developed that used ion-specific electrodes to measure individual electrolytes. The first commercial clinical laboratory instruments capable of measuring more than one electrolyte—in this case sodium and potassium—were a direct result of this work. The evolution of portable clinical blood analyzers has continued well into the 1990s; one current device being assessed for routine use in the U. Another application conceived to meet spacecraft safety requirements that has proven useful on Earth is a water 4,5 treatment device that quickly and easily disinfects drinking water. Patent 5176836) is a self-replenishing resin bed that imparts biocidal amounts of iodine to recycled drinking water. This water-treatment device is especially useful for treating water supplies that may have been contaminated through floods or other natural disasters. A final example, an automated microbial analysis system, represents a particularly elegant combination of miniaturization, speed, automation, and ease of use. Traditional methods of screening biological samples for potential pathogens can take up to 4 days. Speeding up this process can reduce hospital stays by allowing infectious agents to be identified more quickly, as well as reducing the indiscriminant use of antibiotics to treat unidentified 6,7 infections. Inventors of another system devised for use in space have miniaturized and automated the process by which microbial pathogens are identified and their susceptibility to antibiotics tested. Tiny samples of body fluids are injected onto disposable credit-card sized microplates. Each plate contains 16–30 wells that hold chemical substrates for microbial growth or inhibition, which are chosen so that a positive reaction generates a change in color or turbidity in the well. The treated cards are placed in trays, which in turn are placed in a reader/incubator module. The system scans each well for chemical reactions every 60 minutes, and compares the reactions taking place with those in a computerized database of identified microorganisms. Once an organism is identified, the sample is tested in the same way for susceptibility to several antibiotics. The entire process takes between 4 and 13 hours, compared with two to four days for traditional culture preparations. This system allows Earth-based microbiology laboratories to provide guidelines for antimicrobial treatment within one day of specimen collection. Other advantages include the minimization of human error, reductions in technician time, and increases in laboratory output. This system also has broad applicability beyond medicine, such as in food processing; identification of biological indicators or contaminants in sterilization processes; and in-plant environmental testing.
Regulations You must review and discuss with the driver any "yes" answers Does the driver use medications to: blood pressure 120 80 generic coumadin 5mg on line. Page 209 of 260 Recommendations Question that you may ask include Does the driver experience: hypertension htn discount coumadin 5mg line.

The drug schedules are based on addiction potential and medical use but not on side effects. These substances include many opiates, opiate derivatives, and hallucinogenic substances. Abuse may lead to moderate or low physical dependence or high psychological dependence. Schedule V drugs have the lowest potential for abuse and include narcotic compounds or mixtures. Therefore, a substance can have little risk for addiction and abuse but still have side effects that interfere with driving ability.

Driver Information A complete physical examination is required for new certification and recertification. Verify that the date of the examination is accurate because this is used to calculate the expiration date. Any individual can request and be given a Federal Motor Carrier Safety Administration physical examination. Health History the health history is an essential part of the driver physical examination. Discuss the safety implications of effects and/or side effects of prescription and over-the-counter medications, supplements, and herbs. By signing the form, the driver certifies that the information and history are ?complete and true. Document the significant findings of the health history in the comments section below the signature of the driver. Medical Examination Report Form Page 2 the results of the four required tests: vision, hearing, blood pressure/pulse, and urinalysis are recorded on the second page of the Medical Examination Report form. Abnormal test results may disqualify a driver or indicate that additional evaluation and/or testing are needed. Drug and alcohol testing are not required for the driver physical examination unless findings indicate they are needed to determine medical fitness for duty. Vision the medical examiner or a licensed ophthalmologist or optometrist can examine and certify vision test results. Page 213 of 260 Visual acuity is measured in each eye individually and both eyes together:. Distant visual acuity of at least 20/40 (Snellen) in each eye, with or without corrective lenses. Color vision must be sufficient to recognize and distinguish traffic signals and devices showing the standard red, amber, and green colors. When corrective lenses are used to meet vision qualification requirements, the corrective lenses must be used while driving. A driver with monocular vision, who is otherwise medically qualified, may apply for a Federal vision exemption. You may certify the driver who meets vision qualification requirements, with or without the use of corrective lenses, for up to 2 years. Hearing To qualify, the driver must meet the hearing requirement of either the forced whisper test or the audiometric test in one ear. Forced whisper test is to first perceive a forced whispered voice, in one ear, at not less than five feet. The driver who wears a hearing aid to meet the hearing qualification requirement must wear a hearing aid while driving. Blood Pressure/Pulse Record pulse rate and rhythm on the Medical Examination Report Form. The driver with stage 1 or stage 2 hypertension may be certified in accordance with the cardiovascular recommendations, which take into consideration known hypertension history.
