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

Can taking my peak flows trigger a bronchiospasm? When I take my peak flows my first blow is always higher than the last 2.

Mechanism....: Using a peak flow meter is effort-dependent. So, the first time you force air into the meter, you will likely give a better effort so the number will be a bit higher. If you rest a minute or 2 between trials, the numbers will likely be closer together. It is good that you are monitoring the peak flows so see if resting helps. If symptomatic, see your doctor or go to ER for evaluation and treatment ...Read more

Chart says nrml peak flow for womn my age is 422 so a peak flow of 390 not so diffrnt my norm is 600 is it different if I blow 390? In terms of asthma

Albuterol?: A lot depends on if the peak flow measurements are all done on the same machine or device. A peak flow of 600 on a hand held portable plastic device may be equal to a different number on an office spirometer. If you use the same device and your level falls from 600 to 390 then that is significant and you probably should be using albuterol, your quick reliever. ...Read more

I'm worried because my peak flow was 120-140, what do you suggest?

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

What to do if I have one of those small peak-flow meters but it is not helping me. I have copd. What can help me breathe better?

Bronchodilators: Peak flow meters do not help with breathing, they measure the flow of the breathing effort. To improve the flow you need to use bronchodilators which open the airways and allow the air to pass through more easily. There are many inhalers that could help and a consultation with your pulmonologist may be a good option to help with finding the right balance of therapy. ...Read more

Treatments....: Treatments for COPD include bronchodilator inhalers and sometimes steroid inhalers. If your oxygen level is low, either at rest, with activity or while sleeping, supplemental oxygen can be prescribed. If you are still smoking, you need to quit ASAP and your doctor can help with that as well. See a lung doctor to be sure you are getting the best treatment possible, if you haven't done that already! ...Read more
