This utility model discloses an intelligent air mattress for turning over and preventing pressure sores in critically ill cardiovascular patients, belonging to the field of medical device technology. The utility model includes a base plate with a baffle fixedly connected to the top outer wall of the base plate. By setting up a control panel and automatic telescopic rods, the extension distance of multiple automatic telescopic rods at the bottom can be changed by operating the control panel, thereby causing the automatic telescopic rods to push one side of the air mattress upwards. The other side of the air mattress is confined to the base plate, so the movement of the automatic telescopic rods causes the air mattress to bend, with the bending part precisely near the waist.
