What is tourniquet time?
The safe duration and pressure for tourniquet. Use of tourniquet for >2 h and pressures of >350 mm Hg in lower extremity and >250 mm Hg in upper extremity increases the risk of compression neurapraxia. If >2 h is required, the tourniquet should be deflated for 5 min for every 30 min of inflation time.

- Take the patient’s blood pressure and record it, for example, 100/70.
- Inflate the cuff to a point midway between SBP and DBP and maintain for minutes. (
- Reduce and wait 2 minutes.
- Count petechiae below antecubital fossa.
- A positive test is 10 or more petechiae per 1 square inch.
What is a tourniquet in first aid?
Tourniquets are tight bands used to control bleeding by completely stopping the blood flow to a wound. Tourniquets work only on arm and leg injuries; you can’t exactly wrap a tight band around a patient’s neck and cinch it down to stop the flow of blood.

Why are tourniquets dangerous?
Applying a tourniquet too tightly or loosely can pose danger to nearby tissue and increase the odds of irreversible nerve and muscle damage. The tourniquet should provide only as much pressure as needed to halt arterial blood loss.
Is a tourniquet a last resort?
In its outline of how to control severe bleeding, it indicated that a tourniquet is used “only” as a last resort since it may “cause gangrene” and “may require surgical amputation of the limb.” The handbook also advises that in the event that a tourniquet must be used, that it should be loosened in “five minute” …

What is tourniquet effect?
Local effects of arterial tourniquets result from tissue compression beneath the cuff and ischaemia distal to it. Tissue compression predominantly affects nerve tissue, whereas muscle is more susceptible to ischaemia. Widespread systemic effects of arterial tourniquets usually result from cuff inflation and deflation.
In what circumstance is it appropriate to use a tourniquet?
A tourniquet may be appropriate if you cannot reach the wound because of entrapment, there are multiple injuries, or the size of the wound prohibits application of direct pressure.
