[MTS] How can we determine if a patient is just “hot” compared with “very hot” over the telephone?

Very hot is classed as a temperature of >41°C however it is acknowledged that when performing
telephone triage the patient/caller may not have a thermometer to hand. Therefore the clinician should
look for other signs associated with this level of pyrexia, aside from hot skin, which include decreased
level of consciousness, ataxia, muscle rigidity, confusion and possible absence of sweating (these
signs/symptoms are consistent with heat stroke). In the absence of these, the patient may be classed as
hot.
