What are the electric tourniquet pressures for lower and upper limbs?

The pressure of an electric tourniquet should be approximately 400 mmHg for the lower limbs and about 200 mmHg for the upper limbs, although specific settings should be determined based on individual patient conditions.

1. Lower limb pressure

If a patient undergoes lower limb surgery, an electric tourniquet should be used to prevent excessive bleeding. Generally, the tourniquet pressure for adult lower limbs should be maintained around 400 mmHg. In principle, it should be higher than 300 mmHg but lower than 500 mmHg, with adjustments made according to the individual's circumstances. For pediatric patients, the pressure should be reduced.

2. Upper limb pressure

For most adults, upper limb tourniquet pressure should be approximately 200 mmHg, typically kept below 300 mmHg to avoid health risks from excessive pressure. For children, even lower pressure is required because their bones are more delicate; thus, higher pressures could cause additional harm.

Patients with specific needs are advised to select appropriate electric tourniquet pressures according to their individual conditions. If discomfort or adverse reactions occur during use, medical advice should be sought promptly.
