Abstract: The dynamically changing epidemiological situation caused by the SARS-CoV-2 virus is associated with the increased burden and fatigue of medical personnel. The aim of the study was to evaluate: (1) oxygen and carbon dioxide blood pressure and saturation levels in medical personnel caring for patients isolated due to SARS-CoV-2 in ICUs; (2) adverse symptoms reported by medical personnel after leaving the isolation zone. Design: A Prospective Cohort Study. Methods: The project was implemented in the first quarter of 2021. Medical personnel working with patients isolated due to SARS-CoV-2 in the ICU of three hospitals were eligible for the study. The participants of the study were subjected to two analyses of capillary blood by a laboratory diagnostician. Results: In the studied group of medical personnel (n = 110) using FFP2/FFP3 masks, no significant differences ( p > 0.05) were found between the parameters of geometric examination performed before and after leaving the isolation ward of the hospital. After working in the isolation ward, nurses reported malaise (somnolence, fatigue, sweating, dizziness) more often than paramedics (44% vs. 9%; p = 0.00002). The risk of ill-being in nurses was approximately nine times higher than in paramedics (OR = 8.6; Cl 95%: 2.7 to 26.8) and increased with the age of the subjects (OR = 1.05; Cl 95%: 1.01 to 1.08). Conclusion: FFP2/FFP3 filter masks did not worsen blood oxygenation in medical staff caring for patients isolated due to SARS-CoV-2 in the ICU. The presence of subjective symptoms such as fatigue may be due to lack of adequate hydration.
