Removing a tourniquet may also create additional risks.
Medical authorities recommend pressure immobilisation for suspected Australian terrestrial snakebites, not arterial tourniquets.
The distinction is crucial.
A pressure bandage is intended to slow lymphatic movement while maintaining circulation.
A tourniquet may interrupt blood flow and cause avoidable harm.
Rule 4: DO Apply a Pressure Immobilisation Bandage
Pressure immobilisation is a central part of recommended Australian snakebite first aid.
The aim is to limit the movement of venom through lymphatic pathways while keeping the affected limb still.
Where available, use a broad, firm elastic or appropriate pressure bandage.
Place the bandage over the bite area, then bandage the length of the affected limb, starting near the fingers or toes and working upwards.
The bandage should be firm, similar to the pressure used to support a sprained ankle, without stopping blood circulation.
A second bandage may be needed to cover the entire limb.
Once the bandage is applied, immobilise the limb with an appropriate splint.
