The pressure of a gas or vapour in its critical state.
 Example sentencesExamples
-  Increases of surface pressure were recorded for different initial lipid surface pressures to determine the critical pressure of insertion of the peptide into lipids.
 -  Pharyngeal critical pressure is the pressure below which occlusion and cessation of airflow occurs.
 -  The flow-limited segment of the pressure-flow relationship is used to define the critical pressure as the nasal pressure at which airflow ceases.
 -  Miscibility critical pressure is a sensitive function of the lipids in the monolayer.
 -  The current work shows that lipid asymmetry and unsaturation both result in high critical pressures in monolayers.
