An example of convection related heat loss would be a cool breeze. An example of a convection related heat gain would be the warm air currents in a heated isolette. An example of radiant heat loss would be the micropreemie infant in a single walled isolette next to a cold window. The infant would become cold regardless of the fact that he is in a heated isolette. Conversely, in the same situation but by a warm window in the sun, the infant would become to warm due to radiant heat gain.
Evaporative losses imply a loss of heat by moisture vaporizing from the surface of the skin.
The best example of evaporative losses is in the delivery room where post delivery wet infants are not properly dried to minimize their losses. An example of evaporative gain would be the humidity provided in a ventilator circuit.
