According to the American Society of Anesthesiologists’ design manual, the number of PACU bed spaces required is 1.5 to 2.0 per OR, but this number will depend on many factors, including surgical case mix, recovery times, and the turnover time of both the PACU and the OR (2012). A large number of short, fast, and ambulatory cases or intensive care unit (ICU) patients with long recovery times will increase the number of beds required. It is important to gain insight into these factors and model patient flow through the OR and PACU to ascertain the required number of beds for optimal patient throughput (Schoenmeyr et al., 2009).
