Table 2 Key components of PCM cooling mattresses for the induction of TH [33]
Component | Description |
|---|---|
Insulated cradle | • Provides the base for the other components. • Made of plastic. • Insulated to make temperature control last longer. |
Bottom PCM layer | • Melting point of 29.0 °C. • Core component of the PCM cooling mattress. • Helps to achieve therapeutic hypothermia by passively absorbing the heat from the newborn’s body. |
Middle PCM layer | • Melting point of 21 °C. • Can be added during induction of therapeutic hypothermia in case the bottom PCM layer is not sufficient to achieve target temperature of 33.5 °C, for example due to high temperature of the external environment. |
Conduction mattress | • Made of gel. • Helps to transfer the heat from the newborn’s body to the PCM layers. • Provides a smooth surface for the baby to lie on. |
