b'ChapterHeat StrokeHeat stroke occurs when the heat regulating control mechanism thermostat fails.The body becomes dangerously overheated and cooling systems start to break down. Sweating stops because fluid levels are very low so therefore the body can no longer effectively cool down. Body temperature rises dramatically (40.6C or more) resulting in dysfunction of the brain, heart and kidneys. Heat stroke can occur suddenly and lead to unconsciousness within minutes.How to RecogniseVery high body temperature (over 40C) with hot, dry, red skin (no sweating).Headache, dizziness, confusion, weakness, irritability.Full, bounding pulse (heart is working harder to rid the body of heat).Rapid and progressive deterioration of conscious responses.Pulse may become weak and irregular as consciousness deteriorates.Patient may vomit and experience seizures.How to ManageQuickly move the patient to a cool place. Discreetly remove as much outer clothing aspossible.Call Ambulance 000.Constantly cool the patient by applying cold/wet sheets to the skin. Fan the patient or spray with water to help evaporate the heat.Wrapped ice packs can be placed under thearmpits, groin area and around the neck.Give plenty of water to drink if conscious. If condition worsens or the patient becomes unconscious: Place the patient into the recovery position.Closely monitor patient for response, airway, normalbreathing while waiting for Ambulance and be prepared to resuscitate.Continue with the cooling process. When the temperature falls to a safe level, you may cover thepatient, however if the temperature starts to rise again, repeat the cooling process.136 Heat and Cold Emergency'
