This document summarizes the results of a simulation study that compared the ability of lifeguards and "patrol support" personnel to detect simulated drowning victims. The study found that while both groups' detection times improved after additional training, patrol support personnel were initially slower to detect drowning behaviors than traditionally trained lifeguards. Factors like age, sleep deprivation, and humidity/temperature were also found to impact detection times. Based on these results, the researchers question whether non-swimmers could effectively be used for surveillance duties to support lifeguards, and they plan to conduct further workplace studies on this topic.
