Gas Laws by Richard Tune https://padlet.com/rich_tune/84354kwbzxnk Describe the four Gas Laws en-us 2018-04-24 07:57:08 UTC 2022-10-05 14:52:42 UTC hello@padlet.com Henry's law is one of the gas laws, formulated by the British chemist, William Henry, in 1803. It states that: At a constant temperature, the amount of a given gas dissolved in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid. https://padlet.com/rich_tune/84354kwbzxnk/wish/254856169
How does this relate to paramedic practice?

The law, discovered by Robert Boyle in 1662, states that at a fixed temperature, the volume of gas is inversely proportional to the pressure exerted by the gas.

Can you combine this with the other thread? Rich]]> 2018-04-24 14:41:00 UTC https://padlet.com/rich_tune/84354kwbzxnk/wish/254856197 Charles Law https://padlet.com/rich_tune/84354kwbzxnk/wish/254856236 Charles’ Law is a principle law stating that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature. In other words; a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure.

How does this relate to paramedic practice? (i might have dropped a hint can you think of any others?)

Each time they collide with the walls, they exert a force on them. More collisions mean more force, so the pressure will increase.When the volume decreases the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume. https://padlet.com/rich_tune/84354kwbzxnk/wish/254858576

The partial pressure controls the number of gas molecule collisions with the surface of the solution. If the partial pressure is doubled the number of collisions with the surface will double. The increased number of collisions produce more dissolved gas. Therefore, if the patient receives a higher level concentration of oxgyen, therefore increasing the partial pressure of oxygen concentration, there will be a geater amount of oxygen that can diffuse across the alvioli membranes.

In relations to paramedics. It can effect a transfer of patients in air ambulance or even patients that have been mountaiering. 
More commonlypeople that suffer low cardiac output, anemia, poor o2 saturation can suffer from hypoxia at much lower levels ]]> 2018-04-28 14:38:57 UTC https://padlet.com/rich_tune/84354kwbzxnk/wish/256227812
