The COVID-19 outbreak has increased healthcare workers\u2019 use of face masks. This study aimed to evaluate changes in cerebrovascular response among healthcare workers using surgical and N95 respirator masks. Methods \u2013 90 healthcare workers: 30 wearing surgical masks, 30 wearing N95 respirators, and 30 without masks were included. After two-hour of face mask use, the baseline mean flow velocity (MFV) and the mean breath-holding index (BHI) of the bilateral middle cerebral arteries (MCAs) were evaluated with transcranial Doppler ultrasound. The presence of de-novo headache was recorded. BHI values below 0.69 were evaluated as a sign of impaired cerebrovascular reactivity (CVR).  Results \u2013 The rate of de-novo headache was significantly higher in the N95 respirator mask group (p = 0.004). Compared to the control and surgical mask groups, the N95 respirator mask group had significantly lower values of the baseline MFV of the right MCA (p = 0.003 and p = 0.021, respectively) and mean BHI (p = 0.003 and p = 0.012, respectively). Still, only one N95 respirator mask user had a mean BHI value below 0.69. Conclusion \u2013 Surgical masks did not significantly affect cerebral hemodynamics. Although N95 respirator mask use significantly decreased BHI values, the CVR is still within normal limits, and the development of de-novo headache is not directly associated with low CVR.<\/jats:p>","DOI":"10.18071\/isz.77.0263","type":"journal-article","created":{"date-parts":[[2024,7,31]],"date-time":"2024-07-31T09:08:27Z","timestamp":1722416907000},"page":"263-271","source":"Crossref","is-referenced-by-count":1,"title":["Effect of surgical mask and N95 respirator mask use on cerebrovascular reactivity"],"prefix":"10.18071","volume":"77","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8857-9210","authenticated-orcid":false,"given":"Asl\u0131","family":"Yaman Kula","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0325-8691","authenticated-orcid":false,"given":"Sultan","family":"Me\u015fe","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4954-6402","authenticated-orcid":false,"given":"Vildan","family":"G\u00fczel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5813-3397","authenticated-orcid":false,"given":"Ay\u015feg\u00fcl","family":"Yabaci Tak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8161-9096","authenticated-orcid":false,"given":"Mehmet","family":"Yi\u011fit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8765-4418","authenticated-orcid":false,"given":"Serdar","family":"Balsak","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9563-9488","authenticated-orcid":false,"given":"Talip","family":"Asil","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"7411","published-online":{"date-parts":[[2024]]},"container-title":["Ideggy\u00f3gy\u00e1szati szemle"],"original-title":[],"link":[{"URL":"https:\/\/elitmed.hu\/en\/publications\/clinical-neuroscience\/effect-of-surgical-mask-and-n95-respirator-mask-use-on-cerebrovascular-reactivity\/pdf-open","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,7,31]],"date-time":"2024-07-31T09:08:37Z","timestamp":1722416917000},"score":1,"resource":{"primary":{"URL":"https:\/\/elitmed.hu\/en\/publications\/clinical-neuroscience\/effect-of-surgical-mask-and-n95-respirator-mask-use-on-cerebrovascular-reactivity"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024]]},"references-count":0,"journal-issue":{"issue":"7-8","published-online":{"date-parts":[[2024]]},"published-print":{"date-parts":[[2024]]}},"URL":"https:\/\/doi.org\/10.18071\/isz.77.0263","relation":{},"ISSN":["0019-1442","2498-6208"],"issn-type":[{"type":"print","value":"0019-1442"},{"type":"electronic","value":"2498-6208"}],"subject":[],"published":{"date-parts":[[2024]]}}}
