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 &gt; 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.<\/jats:p>","DOI":"10.3390\/ijerph18189425","type":"journal-article","created":{"date-parts":[[2021,9,7]],"date-time":"2021-09-07T02:44:18Z","timestamp":1630982658000},"page":"9425","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Evaluation of Capillary Blood Gases in Medical Personnel Caring for Patients Isolated Due to SARS-CoV-2 in Intensive Care Units before and after Using Enhanced Filtration Masks: A Prospective Cohort Study"],"prefix":"10.3390","volume":"18","author":[{"given":"Wioletta","family":"M\u0119drzycka-D\u0105browska","sequence":"first","affiliation":[{"name":"Department of Anaesthesiology Nursing and Intensive Care, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0052-5654","authenticated-orcid":false,"given":"Daniel","family":"\u015al\u0119zak","sequence":"additional","affiliation":[{"name":"Department of Medical Rescue, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marlena","family":"Robakowska","sequence":"additional","affiliation":[{"name":"Department of Public Health & Social Medicine, Faculty of Health Sciences, Medical University of Gda\u0144sk, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3498-6229","authenticated-orcid":false,"given":"Przemys\u0142aw","family":"\u017buraty\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Medical Rescue, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0582-7088","authenticated-orcid":false,"given":"Kamil","family":"Krzy\u017canowski","sequence":"additional","affiliation":[{"name":"Department of Medical Rescue, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Ma\u0142ecka-Dubiela","sequence":"additional","affiliation":[{"name":"Department of Internal and Pediatric Nursing, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sebastian","family":"D\u0105browski","sequence":"additional","affiliation":[{"name":"Department of Medical Rescue, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2640-3791","authenticated-orcid":false,"given":"Katarzyna","family":"Zorena","sequence":"additional","affiliation":[{"name":"Department of Immunobiology and Environment Microbiology, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1647-5724","authenticated-orcid":false,"given":"Katarzyna","family":"Lewandowska","sequence":"additional","affiliation":[{"name":"Department of Anaesthesiology Nursing and Intensive Care, Faculty of Health Sciences, Medical University of Gda\u0144sk, D\u0119binki 7, 80-211 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9457-9388","authenticated-orcid":false,"given":"Dorota","family":"Ozga","sequence":"additional","affiliation":[{"name":"Institute of Health Sciences, College of Medical Sciences of the University of Rzeszow, St. Warzywna1A, 35-310 Rzeszow, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karina","family":"Chmielarz","sequence":"additional","affiliation":[{"name":"Department of Laboratory Diagnostics, Nicolaus Copernicus University of Toru\u0144, Collegium Medicum im.
