Pressure And Gases Flashcards
What is pressure?
Pressure= Force/Area
What is pressure measured in?
Pascal (Pa) = 1N per square metre
What is static liquid?
Evenly distributed pressure in all directions
Fluid in containers:
Subject to effects related to VOLUME and ATMOSPHERIC pressure/gravity
Bernoulli effect/ Venturi Barrel
Principle of entertainment
Iv fluids:
The higher the fluid container.. the…
Faster the outward flow of the fluid patient
Syringe use:
Pressure is higher from…
Smaller syringes
What is blood pressure?
When heart contracts and relaxes creating pressure within vessels
Constricted vessels can ___ flow and ___ blood pressure
Reduce
Increase
Dilated vessels can ___ flow and ___ blood pressure
Increase
Reduce
What also effects blood pressure?
The pumping efficiency of the heart
Gas laws
A gas is a collection of particles in constant, rapid motion
Aka Brownian motion
Low density
Easy to compress
Boyle’s law
The absolute pressure (P) by a given mass of an ideal gas is inversely proportional to the volume it copies if the temperature and amount of gas remains unchanged within a closed system
Boyle’s law
As volume occupied increases, pressure___
Decreases
Boyle’s law
As volume occupied decreases , pressure___
Increases
