In medicine, pulmonary function tests, also called respiratory function tests, are "measurement of the various processes involved in the act of respiration: inspiration, expiration, oxygen and carbon dioxide exchange, lung volume and compliance, etc.[1]
Pulmonary function tests include:
- Blood gas analysis
- Capnography
- Exercise tests
- Lung volume measurements
- Peak expiratory flow rate
- Spirometry
- Ventilation-perfusion ratio (V/Q scan)
While precise measurements of these parameters take specialized equipment, often requiring considerable operator skill, it is worth noting that inexpensive peak flow meters are a vital part of patient self-management of asthma and several other respiratory diseases.
