pressure

Introduction

• a force acting in any direction against resistance.
• the force/unit area exerted by a gas or liquid against the walls of a container

Pressure units relative to pascal (Pa) units.

pressure	conversion factor	pascal
lbs/cm2	98.07	Pa
atm	101,300	Pa
torr	133.3	Pa
cm H2O	9807	Pa
mm Hg	133.3	Pa
bar	100,000	Pa
dynes/cm2	0.1	Pa

Notes

• includes pressure measurement, thus the more general term 'clinical procedure'
