ECMO-/ECLS

Equipment Used To Minimize Heat Loss In Neonates
 Radiant Warmer
 Provides ease in visualizing and handling infant.
 A large difference in surface temperature between exposed and unexposed
areas exists; therefore, insensible water loss (evaporative heat loss) is
approximately 50% higher than that of convective incubators.
 Convective Incubator
 Humidity controlled and therefore reduces evaporative heat loss
 Double walls serve to decrease radiative heat loss
 Portholes serve to decrease convective heat loss
 Incubator rubber foam mattress serves to decrease conductive heat loss.
 3 Modes of Temperature Control
 Skin temperature servocontrol
· Heater power output automatically adjusts to changes in temperature
based on skin temperature probe
· Variable air temperature
· Constant skin temperature
· Best mode for very low birth weight and extremely low birth weight
neonates
 Air temperature servocontrol
· A constant air temperature within incubator is maintained
· Stable air environment
· Neonate not part of thermal feedback loop
