How often should the tourniquet be loosened

According to medical expertise, the relaxation interval for using a tourniquet is usually set at 15-30 minutes, but this time is not absolute and may be adjusted due to factors such as individual differences, disease status and environmental conditions.

The main purpose of using a tourniquet is to block blood circulation for medical procedures such as blood testing and stopping bleeding. The relaxation interval is determined taking into account the risk that tourniquet pressure may cause limb ischemic necrosis. Relaxation at regular intervals of 15 to 30 minutes can effectively prevent or reduce the risk of complications.

However, the specific relaxation interval needs to be adjusted according to the individual situation and disease state. For example, patients with heart disease, diabetes, peripheral vascular disease, etc., may need to shorten the relaxation interval to reduce potential harm.

In addition, environmental conditions, such as temperature, humidity, etc., can also have an impact on the use of tourniquets. High temperatures may accelerate blood loss, and low humidity may dry out the skin and cause skin problems, which may require adjusting the interval between tourniquet releases.

In summary, the relaxation interval for using a tourniquet is generally 15-30 minutes, but it will vary depending on individual, disease, environment and other factors. Understanding the correct use of tourniquet can protect the life safety of patients more effectively. At the same time, any doubts and problems should be timely consulted by professional medical personnel to obtain the most accurate personalized medical guidance.
