Question 20

What is radiation heat loss

Answer 20

Radiation: heat loss to the environment, approx. 40% of heat loss in pt

Question 21

What is convection heat transfer?

Answer 21

Convection: loss of heat to air immediately surrounding the body, approx. 30%

Question 22

What is evaporation heat transfer?

Answer 22

Evaporation: latent heat of vaporization of water from open body cavities and respiratory tract, approx. 8-10%
(sweating)

Question 23

What is conduction heat transfer?

Answer 23

Conduction: heat loss due to direct contact of body tissues or fluids with a colder material, negligible
