What is the minimum lung capacity required to stay alive?

There is no specific minimum lung capacity required to stay alive, as it can vary depending on factors such as an individual's overall health, age, and activity level. However, a person's lung capacity can be measured using a variety of methods, such as a spirometry test, which can provide an indication of overall respiratory function.

Generally speaking, a healthy adult male typically has a lung capacity between 5-6 liters, while a healthy adult female typically has a lung capacity between 3-4 liters. However, these are just average ranges and individual variations can be significant.

A very low lung capacity, which may be caused by underlying medical conditions such as chronic obstructive pulmonary disease (COPD) or cystic fibrosis, can lead to respiratory distress and decreased oxygen levels in the blood. If left untreated, severe respiratory conditions can become life-threatening.

Therefore, it's important for individuals to maintain good respiratory health and seek medical attention if they experience persistent respiratory symptoms or have concerns about their lung capacity.
