Critical closing pressure
 | This article needs additional citations for verification. (August 2023) |
Critical closing pressure is the internal pressure at which a blood vessel collapses and closes completely.[1] When blood pressure falls below critical closing pressure, the vessel is unable to overcome external pressure (either from environment or vascular smooth muscle) and flow stops. An example of this phenomenon is measurement of blood pressure using the "pulse obliteration method" with a sphygmomanometer.
At resting state the arterial critical closing pressure is ~ 20
mmHg

Critical closing pressure in
mean vascular filling pressure that develops after death (~7 mmHg). Therefore, arteries collapse after death, then fill up with air once the dissection
begins.
