A system such as a hospital bed provides capability to monitor and alleviate the pressure points and provides oxygen and water jets to prevent and treat bed sores in bed-ridden patients. An array of balloons touching each other form a mattress of unstitched but contiguous balloons like in a conventional mattress with stitched puffs. Individual pressure sensors placed within each balloon measure and monitor pressure. Furthermore, horizontal rods which lay between the balloons perform oxygenation and provide water massage to the back of the patient body from the interstitial spaces within the unstitched mattress of contiguous balloons. The rods are elevated to raise the patient above the mattress to relieve overall pressure and enable cleaning and wipe down of the back of the patient body. The rods can elevate the entire patient body or its torso alone or the lower extremities alone to clean as desired.
