A Study on the Phenomenon of Remote Ischaemic Preconditioning in Patients With Peripheral Artery Disease

"An automated device performs four 5-minute episodes of upper limb ischemia in which the cuff pressure in the experimental group remains at 200 mmHg for 5 minutes, causing and ensuring ischemia. Ischemic episodes alternate with 5-minute reperfusion. The intervention lasts a total of 35 minutes. The participant places the device on his upper arm and presses the Start button, starting the intervention. The intervention takes place at rest in the patient's home environment daily for 28 days. During the first visit to the research center, the research assistant teaches the participant how to use the device. The device measures the patient's blood pressure at the start of the intervention. If the patient's blood pressure is above 200 mmHg, the device will not perform the intervention."

The automated device simulates the intervention of the experimental group with the difference that the device does not apply pressure to the upper limb and, therefore, no ischemia occurs.
