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

In a pressure control mode of ventilation, the primary focus is on maintaining a set pressure during the inspiratory phase of ventilation. The ventilator delivers a breath until the predetermined peak inspiratory pressure is reached, regardless of the volume delivered. This means that the parameters such as volumes are not continuously monitored as they are in volume control modes, where a specific tidal volume is targeted.

In pressure control ventilation, it is critical to monitor the pressures to ensure the desired pressure limit is not exceeded, as elevated pressures can cause barotrauma or other lung injuries. The ventilator will continuously assess the pressure in the breathing circuit to ensure that it adheres to the set limits, allowing for adjustments in flow or inspiratory time based on the patient's needs and lung mechanics. Therefore, monitoring pressures is essential for patient safety and effective ventilation management, as it reflects the compliance of the respiratory system and indicates how effectively the lungs are being ventilated under the current settings.
