Module 1 - Pressure and Static Pressure Flashcards
An effect when force is applied on a given area
Pressure
When the same force is concentrated in a small area, the pressure on this area will be ———-
Greater
The greater the area over which force is applied, the —- pressure is exerted
Less
What is the standard unit of pressure
Pascal (Pa) or kilopascal (kPa)
What is the measurement of normal air pressure
101.3kPa
What is the measurement of blood gases: partial pressure of o2
13.3kPa
British units of pressure
Pounds/square inch (psi)
Air in car tyres =
28psi or 190kPa
Pressure exerted by the atmosphere against the body
Atmospheric pressure
What is measured by the displacement of a column of liquid?
Atmospheric pressure
mmHG
Millimeters of Mercury
1 Atm =
760 mmHG
Pressure that blood exerts on the walls of blood vessels
Blood pressure
Used to measure blood pressure
Manometer - sphygmomanometer
The measure of BP is based on the effect that an ——— ——– has on the ——— ————
external pressure; arterial pressure
