Nevertheless, it has been shown that different ambient, body, and test fluid temperatures and also different types of test fluid may affect the penetration process.2 Moreover, wearing personal protective equipment (PPE) might pose a thermoregulation risk to the practitioner by increasing core body temperature.eninfo:eu-repo/semantics/openAccessHumidityTemperaturePenetration PerformanceLetter6881271127110.1007/s12630-021-02004-3Q1N/A
