4.4.4 Pressure Control Ventilation (PCV)
4.4.4.1 Description
Pressure control ventilation (hereinafter referred to as PCV) mode is a basic fully-mechanical
ventilation mode. In the PCV mode, each time mechanical ventilation starts, Paw rises
rapidly to the preset Plimit. Then gas flow slows down through the feedback system to keep
Paw constant until expiration starts at the end of inspiration. The tidal volume delivered in
the PCV mode changes based on patient pulmonary compliance and airway resistance.
In the PCV
mode, you need to set Plimit to prevent high airway pressure from injuring the
patient.
In the PCV mode, you can also select to set [
PEEP
] to improve expiration of end-tidal
carbon dioxide and to increase oxygenation of breathing process.
