What is peak inspiratory pressure?

Peak inspiratory pressure (PIP) is the highest pressure reached in the airway during inspiration. It is measured in centimeters of water (cmH2O). PIP is an important parameter in mechanical ventilation, as it reflects the force required to overcome the resistance of the airway and inflate the lungs.

PIP can be affected by a number of factors, including the patient's lung compliance, airway resistance, and ventilator settings. In general, PIP should be set as low as possible while still providing adequate ventilation. This is because high PIP can lead to a number of complications, including barotrauma, volutrauma, and increased airway resistance.

PIP is typically measured using a pressure transducer connected to the airway. The pressure transducer converts the pressure waveform into an electrical signal, which is then displayed on a monitor. PIP can also be measured manually using a manometer.

PIP is an important parameter to monitor during mechanical ventilation. By closely monitoring PIP, clinicians can help ensure that patients are receiving adequate ventilation without putting them at risk for complications.
