Long-term illness requires the highest standard of a hospital bed as patients who spend prolonged periods laying still will develop uncomfortable bedsores. One way to counteract this is with a medical air mattress, which consists of many cells (air pockets). Thomas offers air compressors for inflating and deflating these cells, which improves the blood circulation and minimizes bedsores. The additional benefit is a better comfort of the sleep of the patient even during prolonged recovery.
