Physiological impact of surgical masks and N95 masks on obese operating room staff.

ABSTRACT: This study aimed to determine whether wearing N95 masks for 4 h significantly affected physiological indicators in obese operating room staff compared to surgical masks (SMs). In this randomized crossover trial, the physiological impacts of wearing SMs and N95 masks for 4 h was analysed among 20 obese operating room staff. The data were connected to a nasal sampling tube using the Capnostream 20p monitor. The primary outcome was the change in venous carbon dioxide partial pressure (PvCO₂) levels at 4-hour intervention. Secondary outcomes included venous oxygen pressure (PvO₂), bicarbonate (HCO₃^-), pH levels, end-tidal carbon dioxide partial pressure (PetCO₂), peripheral oxygen saturation (SpO₂), respiratory rate (RR), pulse
