Bed sores are caused by skin ulcers caused by long-term bed rest. At this time, the anti decubitus mattress can play its role. The device using the bed sore air cushion must put the side of the tubular air cushion upwards, and the air inlet of the air mattress must be placed on the patient. The foot position can reduce the impact of airflow noise on the patient. When laying anti decubitus mattress, whether it is on a wooden or steel wire bed, a layer of bedding should be laid to prevent the air mattress from rubbing against the wooden or steel wire bed.

The anti decubitus mattress is generally inflated for 30 minutes for the first time, and used 12 hours after inflated. When inflating, first check whether the pressure of the air pump is adjusted to the maximum. The first inflation should be adjusted to the maximum. After it is full, adjust the frequency to the middle. Although anti decubitus mattress has a certain preventive effect on patients with bedsores, it is impossible to completely eliminate the occurrence of bedsores. In daily life, we still need to pay attention to the care of patients, turn over frequently, bask in the sun, dry bedding, and eat more nutritious food.
