How Is Lung Capacity Measured? Spirometry is a diagnostic test that provides different measures of lung capacity. It is very often used to diagnose chronic obstructive pulmonary disorder (COPD) or asthma. Moreo
Infection with the acute respiratory syndrome coronavirus-2 (SARS-CoV-2) impairs oxygen diffusion capacity of the lung and in consequence causes hypoxemia. In 20%-40% of COVID-19 cases, patients have alarmingly low oxygen (O2) saturation of the blood without being dyspneic, a condition called...

If the carbon dioxide concentration gets too high, then both types of chemoreceptors signal the respiratory centers to increase the rate and depth of breathing. The increased rate of breathing returns the carbon dioxide concentration to normal and the breathing rate then slows down. Hydrogen ion (...
If the oxygen concentration in the blood decreases, they tell the respiratory centers to increase the rate and depth of breathing. Carbon dioxide: Peripheral chemoreceptors also monitor the carbon dioxide concentration in the blood. In addition, a central chemoreceptor in the medulla monitors the ...
