Application of IPC During Surgery to Prevent Venous Thrombosis in Gastrointestinal Surgery Patients.

During use, the pressure is gradually reduced from large to small, and pressure is applied in steps, starting from the calf and moving up to the thigh. Every 30 minutes, the patient's skin color of the lower extremities is observed for any abnormalities, and the blood supply status of the distal ends of both lower limbs (palpation of the dorsalis pedis artery pulse) is noted. If any special conditions occur, the procedure must be immediately stopped.
