Peak Flow On Ventilator
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
What would cause on lung function tests, DLCO 60-75%, increased TLC and narrowing of air tubes? Finger o2 monitor 90%. Heart is fine, NAD on chest ct
See below: It would be difficult to say without all the numbers. But, if your TLC is high, then that's an indication of hyperinflation, which goes along with COPD. So does the decreased DLCO. But again, this is just generalities; would be glad to review all you results with you if needed. ...Read moreSee 1 more doctor answer
True?False? Laying on ur back during pregnancy slows the return of blood to the heart which reduces blood flow to the fetus less oxygen less nutrients
Depends: early in pregnancy lying on your back is fine. Later in the third trimester some women may be advised to lay on their left side to reduce blood pressure or in cases of poor fetal growth. However, for most women lying on your back is compensated with an increase in your pulse and the oxygen level to the baby is fine. So, for some this is true, but in general is false. ...Read moreSee 1 more doctor answer

Age81/M cant cough, heavy lung congestion, aspiration, saturation 95 at 3 units oxygen, BP, ECG, pulse normal. Troubled breathing due to secretions. ?
Not very unusual: It's not unusual for women on birth control pills to have scant or even no period. It doesn't signify pregnancy, but it can cause you to unnecessarily worry over the possibility. If you are on a low dose BCP with 10-25 mcg of ethinyl estradiol switching to a pill with 30-35 mcg of estradiol may restore normal periods. ...Read more

Constant wheeze at the end if each breath outwards for the last few weeks, although peak flow is normal, inhaler & antihistamines NT clearing wheeze?
Could there be negative affect on lung function slightly below average performance 1yr after being on heart and lung machine for Open Heart Surgery?
Yes, brain, heart &: brain, etc. because clots form in blood while being moved through the long plastic, non-endothelium lined tubing between your chest & within the heart lung machine a few feet away from your body. Thus heparin is infused into the blood shortly after leaving you body (too much would cause excess bleeding) yet can never prevent all microscopic clots which block microcirulation after returned to body. ...Read moreSee 2 more doctor answers

Asthma: You most likely have a bronchial asthma equivalent if you don't experience wheezing. Bronchodilating inhalers,and at times, corticosteroid inhalers should prevent or relieve your symptoms. If you're not doing well a pulmonologist would be best to evaluate and treat you. A normal peak flow weight for you can be from 380-460. ...Read more
By prescription: Peak flow meters are an important part is asthma control. A peak flow meter can be prescribed to you by your doctor. Be sure you know your best reading. Decreases in your peak flow from your best can be a signal that your asthma is not in control and medications need to be adjusted. Your doctor can give you an asthma action plan so that you know what to do if your peak flow is decreased. ...Read moreSee 1 more doctor answer
Normal is 370: You are just barely in the green assuming your normal peak flow is 370. A number of assumptions. You probably have some underlying disorder like asthma or COPD causing your peak flow to be lower? Green means that you are ok, yellow range would be from 300 to 185 and below 185 is the red range. Red range, seek medical attention. Yellow range - you should have a plan with your regular physician. ...Read more

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
Low peak flow: It depends on your baseline peak flow values, but this is low for your age. If this is a significant drop (more than 20% of normal), then either refer to your asthma action plan or call your physician for instructions. If this is not possible, then proceed to urgent care center or ER for respiratory evaluation and treatment. If this is a normal value (ie chronic obstruction), then disregard. ...Read more
Depends: that seems a bit low. Full pulmonary function tests with a pulmonary MD could help clarify the cause. ...Read more

More information/pft: Yes, for most adults, this would indicate an abnormal amount of air being expired. This may indicate obstruction/restriction or a combination of these conditions. Your physician will guide further testing to determine the underlying cause. Asthma is one of the more common causes of a low PEF. ...Read more

Asthma control: Peak flow will improve when your asthma is controlled. Remember if your asthma symptoms are persistent, you need to take a controller medication every day even though you do well. This way, your asthma symptoms are not likely to recur and your peak flow will improve. A controller is usually an inhaled corticosteroid. ...Read more
