What is pressure?
Pressure is the force applied per unit area and is fundamental to understanding medical vacuum technology. In the context of medical devices, pressure is typically measured in units like pascals (Pa) or millimeters of mercury (mmHg). When discussing pressure in a medical setting, it is crucial to differentiate between absolute pressure and gauge pressure.
- Absolute pressure: The total pressure at a point, including atmospheric pressure.
- Gauge pressure: The pressure above atmospheric pressure.
