In ventilator delivery methods, what is continuously monitored in Pressure control?

In Pressure control ventilation, the primary focus is on maintaining a set pressure during the delivery of each breath. This means that the ventilator will adjust the flow and volume as needed to ensure that the predetermined pressure is achieved and maintained. Continuous monitoring of pressures is crucial in this method because it helps to prevent over-distension of the lungs and allows for adequate ventilation without causing barotrauma.

While inspiratory time, volumes, and flow rates are important aspects of ventilatory support, they are adjusted based on the pressure set on the ventilator. The ventilation strategy inherently prioritizes pressure as a controlled variable. This ensures that the patient receives the appropriate amount of pressure support while allowing respiratory mechanics to dictate the volume delivered. Maintaining the desired pressure continuously ensures patient safety and effective ventilation, especially in patients with varying lung compliance or resistance.
