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. Age, gender, body composition, and ethnicity are factors affecting the different ranges of lung capacity among individuals.
particularly, 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.
thus, Is 99 lung capacity good?
The Pulse Oximetry Test
Pulse oximeter readings are expressed as a percentage. As stated above, a reading of 94 to 99 percent or higher indicates normal oxygen saturation, and anything below 90 percent is considered to be low blood oxygen, also known as hypoxemia.
in effect What does 30% lung capacity mean?
30 percent lung capacity, as you may have guessed, is not great. It means your lungs are functioning only a third as well as a healthy person’s. This will be determined by Pulmonary Function Tests (PFTs), which are used to assess lung size and air flow.
Can a person live with 50 percent lung capacity?
Though having both lungs is ideal, it is possible to live and function without one lung. Having one lung will still allow a person to live a relatively normal life. Having one lung might limit a person’s physical abilities, however, such as their ability to exercise.

What is a good number for lung capacity?
Total Lung Capacity(TLC)
It is the maximum volume of air the lungs can accommodate or sum of all volume compartments or volume of air in lungs after maximum inspiration. The normal value is about 6,000mL(4‐6 L).
What percentage should your lung capacity be?
Your FEV1 will fall between 50 percent and 79 percent of the predicted normal values with an FEV1/FVC of less than 70 percent. Symptoms, like shortness of breath after activity and cough and sputum production, are more noticeable. Your COPD is considered to be moderate.
Can lung capacity be increased?
The average person’s lung capacity can be improved around 5 percent to 15 percent even with frequent workouts. Many experts recommend some form of physical exercise at least three times a week. Some doctors may prescribe pulmonary rehabilitation, which combines exercise, education and support.

If your lung volume is lower than normal, this may be a sign of a restrictive lung condition such as pulmonary fibrosis or sarcoidosis. We use your comments to improve our information.
What does 70 percent lung capacity mean?
If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65). When compared to the reference value, a lower measured value corresponds to a more severe lung abnormality.
