Vital signs most interested, in and why, with confusion?
- pulse and respiratory rate - tachycardia/tachypnoea = sepsis, secondary haemorrhage
- blood pressure - hypoperfusion to brain - decreased consciousness
- oxygen sats - hypoxia alters consciousness
- temperature - pyrexia indicates infection
- blood glucose - hypo/hypergycaemia can depress consciousness. T1DM hyperglycaemia may be associated with ketoacidosis. T2DM with extreme hyperglycaemia indicates hyperosmolar non-ketonic state.
