Performance evaluation method of alternating pressure air mattresses using FSA pressure mapping system

Pressure ulcers are among the most common complication found in bed-ridden patients. In Thailand, Alternating Pressure Air Mattresses (APAMs) have been used both in hospitals and home settings to prevent pressure ulcers. Various types of APAMs are commercially available at a variety of prices and features. The performance of these APAMs is still questionable to the users. Pressure Relief Index (PRI) is a promising indicator that can be used to compare the performance of APAMs. This paper presents a simple procedure to evaluate the performance of APAMs based on the concept of PRI by using FSA pressure mapping system. This procedure can be used to relatively compare the performance of APAMs and assist the users in justifying the cost-effectiveness of APAMs.
