Peak Expiratory Flow Rate Chart
Breif: A peak expiratory flow rate is a fairly simple test done, usually as part of a comprehensive pulmonary function test procedure. By itself, a few minutes as one usually is instructed to do several attempts and the best result or average results recorded. A full set of pft's may take 30 minutes to an hour depending on factors like patient cooperation, quality of equipment etc. ...Read more
I would like help to calculate peak blood flow rate in aorta when given radius and peak blood velocity?
Bernoulli Equation: For peak pressure, you only need peak velocity. Peak pressure is 4 x the square of the peak velocity. If the peak velocity is 4 m/s, the peak pressure is 64 mmHg. The peak velocity IS the peak flow rate. For example, if peak velocity is 5 l/min, then the peak flow rate is 5 l/min. Is that what you meant? ...Read more
How does asthma affect routine measurements? Routine measurements : blood pressure, pulse rate, breathing rate, peak flow, body temperature, how and why?
Basal to mid anterior wall hypokinesis noted at peak workload. No ECG clinical evidence of ischemia at a max workload.
Unclear question: Your statement did not provide a question. You obviously are under the care of a doctor and she/he would be better equipped to answer your questions as she/he knows more about your health. ...Read more
30 f resting heart 150bpm according to heart monitor excellent health heart rate drop to 80 when asleep is that normal? Full blood normal.
Lmp aug 26. Consistently measuring 6days behind at u/s. 7w4d 8mm fetal pole. Hr 131 bpm. Is the hr consistent with fetal pole measurement? Healthy?
HR rises & falls twice (Up, down, up, down) during each set of inspiration & expiration. Shown in ANS tests. Variation of normal Sinus Arrhythmia? or?
Sinus arrhythmia: Sinus arrhythmia only reflects an exaggeration of a normal behavior. Everyone's HR tends to vary slightly with the normal changes in pressure in the chest with breathing. Your HR should increase with inspiration and decrease with expiration. If this variation is quite obvious, then we call it a "sinus arrhythmia," but it's not generally clinically significant. ...Read more
Normal peak flow meter test, normal CT of lung, normal chest xray , normal echo, normal pulse ox / blood pressure can this rule out interstitial lung d?
None: In an asthmatic under good control none of these measurements should not be effected. ...Read more
Describe cardiac cycle and relate systole and diastole to the two numbers measuring blood pressure?
Systole and Diastole: The heart is a pump. Every time it beats, it squeezes blood out to the body. The systolic blood pressure is the pressure measurement, in mm Hg, recorded in the arteries when the heart is squeezing. This is the point when the pressure is highest. The diastolic blood pressure is the pressure recorded when the heart is relaxing and is the point when pressure lowest. (e.g. 120/80 = systolic/dias. ...Read moreSee 1 more doctor answer
17 year old active male run 4/5 mi daily,ekg, echo, chest X-ray,blood work normal peak flow meter normal feel lack of air and chest pain for 3 months?
During exercise?: If symptoms only occur during exercise could be exercise induced asthma, narrowing of airways in lungs triggered by strenuous exercise. It causes shortness of breath, wheezing, coughing and discomfort during or after exercise. Treatment can be gotten with medications and certain ways of controlling temperature prior to workouts. ...Read more
Need to Get Checked: There are a few reasons, for this, but because of the high and irregular heartbeat you should be checked as soon as possible. I would recommend being evaluated at your doctor if you can be fit in now, an UC or ER. These could be symptoms of anxiety, but also an "arrhythmia" such as atrial fibrillation or flutter. It needs to be checked out, but don't panic. ...Read more
High blood pressue averages 175/180. Diastlolic average low 60. Pulse rate average 50 at rest. Have been prescribed 5mg amlodipine . Is this ok? 67
Amlodipine for BP: 70 M BP 180/60 prescribed amlodipine 5 mg. OK? I specialize in high BP. I and guidelines would generally do following but check with ur team. First get a number of readings with home device that is accurate on u. See my checklist. Then if above 140 at your age begin DASH eating plan See my checklist.
