Respiratory pressure meter Measuring respiratory muscle strength is a long-established method of assessing the mechanics of breathing. Respiratory muscle dysfunction (i.e., reduced strength or endurance) should be distinguished from lung function abnormalities and measured separately.
It is a marker of respiratory muscle function and strength. [28] Represented by centimeters of water pressure (cmH2O) and measured with a manometer. Maximum inspiratory pressure is an important and noninvasive index of diaphragm strength and an independent tool for diagnosing many illnesses. [29]
Measurement of maximal inspiratory and expiratory pressures is indicated whenever there is an unexplained decrease in vital capacity or respiratory muscle weakness is suspected clinically. Maximal inspiratory pressure (MIP) is the maximal pressure that can be produced by the patient trying to inhale through a blocked mouthpiece.
A spirometer measures ventilation, the movement of air into and out of the lungs. The spirogram will identify two different types of abnormal ventilation patterns, obstructive and restrictive. There are various types of spirometers that use a number of different methods for measurement (pressure transducers, ultrasonic, water gauge).

Capnography is the monitoring of the concentration or partial pressure of carbon dioxide (CO 2) in the respiratory gases.Its main development has been as a monitoring tool for use during anesthesia and intensive care.
The peak expiratory flow (PEF), also called peak expiratory flow rate (PEFR) and peak flow measurement, [1] is a person's maximum speed of expiration, as measured with a peak flow meter, a small, hand-held device used to monitor a person's ability to breathe out air.
Output of a spirometer. Vital capacity (VC) is the maximum amount of air a person can expel from the lungs after a maximum inhalation.It is equal to the sum of inspiratory reserve volume, tidal volume, and expiratory reserve volume.
