ICU/Critical Care/peak flow


A recent breathing test indicated that I was at 60% lung function.  My pulse ox was 97 percent and my chest/lungs were clear.  How is it possible that my vitals are fine but I am at only 60%.  I do get winded from activties that normally do not bother me at all.

I was started on nebulizer med and zyflo cr Friday. How long should it take for my peak flow numbers to start to improve?

Dear Amy,

Peak flow has several measurements. 60% is only one of them. The test is done to identify if you have restrictive disease, like emphysema, or obstructive disease, like chronic bronchitis or asthma. Either way, your sats can be 97% with either lung disease.
