CMH2O

CMH2O is a term used in the field of respiratory therapy and pulmonology to denote the measurement of pressure in centimeters of water. This unit of measurement is commonly used to quantify the pressure exerted by gases or liquids in various medical and scientific applications.

Applications in Medicine

In the medical field, CMH2O is frequently used to measure the pressure within the respiratory system, particularly in the context of mechanical ventilation. It is a critical parameter in ensuring that patients receive the appropriate amount of pressure to maintain adequate oxygenation and ventilation.

Mechanical Ventilation

In mechanical ventilation, CMH2O is used to set and monitor the positive end-expiratory pressure (PEEP) and peak inspiratory pressure (PIP). These settings are crucial for patients who are unable to breathe on their own and require assistance from a ventilator.

Pulmonary Function Testing

CMH2O is also used in pulmonary function testing to measure the pressure generated by the respiratory muscles during inspiration and expiration. This helps in diagnosing and monitoring various respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma.

Measurement Techniques

The measurement of CMH2O can be performed using various devices, including manometers and pressure transducers. These devices are calibrated to provide accurate readings of pressure in centimeters of water.
