Question: 1 / 400

What is the maximum recommended tourniquet time for adults?

60 minutes

90 minutes

The maximum recommended tourniquet time for adults is generally considered to be 90 minutes. This duration is established based on clinical guidelines and studies that indicate prolonged tourniquet application can lead to complications, such as ischemia or nerve damage, if the limb is subjected to lack of blood flow for too long.

After about 90 minutes, tissues may begin to suffer irreversible damage due to the lack of oxygen and nutrients supplied through blood flow. It's essential to balance the need for a tourniquet to control bleeding with the risk of potential harm to the limb. Proper monitoring and adherence to these guidelines ensure patient safety and optimal outcomes in surgical settings.

Understanding this recommended time frame is crucial for surgical professionals to minimize risks during procedures that require the use of a tourniquet.
