How do I read my pulmonary function test results?
The first step when interpreting PFT results is to determine if the forced expiratory volume in one second/forced vital capacity (FEV1/FVC) ratio is low, indicating an obstructive defect.
Physicians have two options to determine if this ratio is low..
How often should you use a spirometer?
Take 10 to 15 breaths with your spirometer every 1 to 2 hours, or as often as instructed by your nurse or doctor.

At what stage of COPD do you need oxygen?
Supplemental oxygen is typically needed if you have end-stage COPD (stage 4). The use of any of these treatments is likely to increase significantly from stage 1 (mild COPD) to stage 4.
How can I test my lung capacity at home?
How It Is DoneSet the pointer on the gauge of the peak flow meter to 0 (zero).Attach the mouthpiece to the peak flow meter.Stand up to allow yourself to take a deep breath. … Take a deep breath in. … Breathe out as hard and as fast as you can using a huff. … Note the value on the gauge.More items…
What is normal inspiratory capacity?
Inspiratory Reserve Volume(IRV) It is the amount of air that can be forcibly inhaled after a normal tidal volume. IRV is usually kept in reserve, but is used during deep breathing. The normal adult value is 1900-3300ml.
What is normal lung function?
It keeps us all alive. Oxygen enters our lungs as part of the air that we breathe. It goes to the blood vessels deep in our lungs and then on to all parts of our body. As our body uses oxygen, it makes a waste product called carbon dioxide.
What is a normal reading on a spirometer?

What is the normal lung capacity?
Lung capacity or total lung capacity (TLC) is the volume of air in the lungs upon the maximum effort of inspiration. Among healthy adults, the average lung capacity is about 6 liters.
What percentage of lung function is needed to live?
“In healthy people without chronic lung disease, even at maximum exercise intensity, we only use 70 percent of the possible lung capacity.”
What do spirometry results show?
Your results A spirometer measures the amount of air you can breathe out in one second and the total volume of air you can exhale in one forced breath. These measurements will be compared with a normal result for someone of your age, height and sex, which will help show if your lungs aren’t working properly.
What does 50 percent lung capacity mean?
If it is only half full, it is 50% full. And 33% means it is only one-third full, and so on. Likewise, if your FEV1 is 50%, your lungs are able to handle only half as much air as they should. If your FEV1 is 33%, your lungs are able to handle even less—only a third as much.
