An evaluation of the Swiss staging model for hypothermia using case reports from the literature

Table 1 Swiss clinical staging of hypothermia

	Brown et al., 2012 [1]	Durrer et al., 2003 [4]	Typical core temperature (°C)
Stage 1	Conscious, shivering	Clear consciousness with shivering	35 to 32
Stage 2	Impaired consciousness, not shivering	Impaired consciousness without shivering	<32 to 28
Stage 3	Unconscious, not shivering, vital signs present	Unconsciousness	<28 to 24
Stage 4	No vital signs	Apparent death	<24

There are minor differences between the original system developed Durrer et al. [4], and the most recent versions [1, 5]. Each clinical stage is associated with an estimate of core body temperature
