Q

Define and describe methods of heat transfer
conduction
convection
radiation
condensation
evaporation

A

conduction: heat transfers by direct contact (touching)
convection: heat transfers between gases & liquids by fluid movement
radiation: heat transfers not by direct contact between 2 substances
condensation: gas - liquid (a cold soda can has small water droplets around)
evaporation: liquid- gas (puddles disappearing)

Q

Boyles law
definition:
equation:
explain gas law:

A

the volume of gas varies inversely with its pressure
(P1 X V1)= (P2 X V2) Multiply then divide
-volume goes up, pressure goes down
-volume goes down, pressure goes up

-volume goes up, temperature goes up
-volume goes down, temperature goes down

29
Q

Poiselles law

A

the degree of resistance in the fluid flow through the tube is directly proportional to its viscosity, flow and length and inversely proportional to its radius & power to the 4th

30
Q

Laplace law

A

something to do with surface tension

31
Q

Humidity definition:

A

the quality of wetness of gas or air in a gaseous state or vapor

32
Q

Absolute humidity definition:

A

the amount or weight of water vapor in a gas

33
Q

Relative Humidity:

A

the ratio amount of water vapor gas to its full saturated capacity at a given temperature

34
Q

Relative Humidity Equation

A

RH%= AB/capacity X 100

35
Q

Explain Characteristics of Humidity

A

-mainly in the nose
-Inhalation: Inspired warm air (convection) & pick up water vapor (evaporation)
-exhalation: cool heat back into ET tube & tracheal (convection)/ cool air less water vapor (rehydration, condensation)

36
Q

Body Humidity

A

ratio amount of water vapor in a gas to its full saturated water vapor content capacity of 44mg/L at a body temperature @37 degrees celsius

37
Q

Body Humidity Equation

A

BH%: AB/44 mg/L X 100

38
Q

efficiency of humidification

A

-duration of contact
-surface area
-thermal mass
-tempurature

39
Q

Humidifier definition

A

a devise used to add water molecule to a gas

40
Q

Indication of humidification

A

-bronchospasm caused by cold air
-humidifying dry medical gases
-overcoming humidity deficit caused by artificial airways

41
Q

humidity deficit definition

A

the amount needed to achieve full body saturated capacity at normal body temperature

42
Q

humidity deficit equation

A

44mg/L- __= __

43
Q

Bubble humidifier

A

-nonheated/nonvented
-15 to 20 mg/L

-infection can spread
-2 nasal prongs goes in nose around ear

44
Q

Passover

A

-vented/heated
-simple reservoir/wicked/membrane
-air goes in heated up by cannula & goes to patient

45
Q

HME

A

-vented/nonheated
-70% body Humidity: 25mg/l in, 40% mg/L out

Q

Identify signs & symptoms of hypoxia

A

-Cardio (heart): tachycardia/ increased work of breathing
