What is the unit of measure for gas pressure in medical applications?

In medical applications, the unit of measure for gas pressure is essential for ensuring the correct administration of gases, such as oxygen, to patients. Both atmospheres (atm) and pounds per square inch (psi) are widely recognized units for measuring pressure.

Atmospheres (atm) are a standard unit that reflects the pressure exerted by the atmosphere at sea level, while psi is a unit commonly used in various applications, including industrial and medical environments. Utilizing these units provides clear communication and ensures consistency when discussing pressures that impact patient care.

Millimeters of mercury (mmHg) is another valid unit used to measure pressure, particularly in relation to blood pressure readings, but it is not as commonly used for the pressure of medical gases in systems directly delivering oxygen or other gases. Liters per minute (L/min) measures flow rates, not pressure, and degrees Celsius (°C) is a temperature measurement, which is unrelated to pressure.

Therefore, knowing that atm and psi are specifically utilized for measuring gas pressure in medical settings highlights the importance of selecting the right units for accurate communication and effective patient management.
