Therefore, we planned to conduct a study in our intensive care unit staff to look for the effects of N95 masks on their health as well as to plan recommendations to ease them.<\/jats:p>\n <\/jats:sec>\n \n Material and Methods:<\/jats:title>\n \n We conducted this study on our intensive care unit nursing staff and HCWs. We noted their oxygen saturation and heart rate at baseline as well as after 1 h, 2 h, 3 h, and 6 h of duty along with their subjective sensations. Institutional ethical clearance for the same was taken. Collected data were entered in MS Excel database and analyzed using SPSS version 20.0. Fisher\u2019s\n Z<\/jats:italic>\n test was applied for comparing proportion and analysis of variance for comparing two means.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n One hundred and nine HCWs participated in this, out of which 93 (85.3%) were females and 16 (14.7%) were males. Eighty-four (77.1%) participants were below 40 years. Twenty-three participants (21.1%) were overweight and 37 (33.9%) were obese. There was no significant drop in saturation and rise in heart rate during these hours.<\/jats:p>\n <\/jats:sec>\n \n Conclusions:<\/jats:title>\n On comparing subjective sensations of HCWs, our study found that feeling of uneasiness was found more in less than 40 years age group as compared to more than 40 years. N95 masks were found to have no impact on cardiovascular system and do not lead to hypoxia while working routinely even for prolonged hours.<\/jats:p>\n
