Evaluation of respiratory function in healthcare workers wearing face masks during the COVID-19 pandemic.

ABSTRACT

BACKGROUND: The COVID pandemic, which has caused high mortality rates worldwide, has mainly affected the working environment of healthcare workers. Metabolic and respiratory changes occur in healthcare workers working with surgical masks. OBJECTIVE: Our aim is to identify the metabolic and respiratory problems faced by healthcare personnel working with surgical masks and to produce solutions to minimize them. METHODS: The study was conducted among emergency service workers who used surgical masks for at least 8 h in the emergency room between June 2020 and July 2020. Venous blood gas samples were taken from the health personnel participating in the study and their vital signs were checked. RESULT: A total of 60 healthcare professionals with a mean age of 28.20 ± 6.30 years were included in the study. The distribution of men and women in the study was balanced with 30 (50.0%) men and 30 (50.0%) women. When the first and last vital signs (blood pressure, pulse, saturation) of the health workers participating in the study were examined, no statistically significant differences were found (p > 0.05). While there was no statistically significant difference in the Na, Chlorine, Ca values of metabolic indicators (p > 0.05), the first measurements of K (0.017) and Lactate (0.037) values were found to be higher than the last measurements (p > 0.05). The first measurements of the respiratory parameters pH (0.002), pCO2 (0.028), sO2 (0.045) and pO2 (0.048) were lower than the last measurements (p > 0.05). The first measurement value of pCO2 (0.028) was found to be higher than the last (p > 0.05). CONCLUSIONS: Regular and long-term use of surgical masks does not harm the body metabolically and respiratorily.
