Peak inspiratory pressure (PIP): the highest airway pressure measured during inspiration. Measures both the resistance of the airways and the compliance of the respiratory system.
Low peak pressure alarm setting – 5 to 10 below peak, should never be set to zero.
High peak pressure alarm setting – 10 to 15 above peak.
When using pressure breaths, the peak pressure should be the pressure setting + PEEP.
PIP vs Pplat
- An elevated PIP with normal Pplat indicates upper airway or resistance issues (mucous plug, kink, over breathing, etc) with normal lung compliance.
- PIP will raise if Pplat raises.
