Tehran University of Medical Sciences Archives of Anesthesiology and Critical Care 2423-5849 8 4 2022 07 29 295 297 Seyed Sadegh Sadrossadat Department of Anesthesiology and Intensive Therapy, University of Szeged, Semmelweis u. 6, Szeged 6725, Hungary. 2022 07 24 Background: Non-invasive mechanical ventilation is one of the most used organ support measures in critical care medicine. Hemet interface has been implemented in everyday practice at ICUs later than classic means of delivery for NIV including face mask. We used helmet interface for first time at ICU and recorded CPAP setting and outcome. Methods: Helmet was used for 9 patients and any complication or side effects were recorded. Also nurses first experience of using the helmet has recorded in a survey. Results: No skin lesion, vomiting, and air leaking were recorded. Also none of the patients complained about claustrophobia, dyspnea, pain, or feeling hot while the helmet was in use. In addition, nursing was easier while using a helmet than it was with face mask. Conclusion: The overall first time use of helmet interface in our department gave us a positive feedback, but more data need to be collected for more effective way of applying  NIV and specifically helmet interface. https://aacc.tums.ac.ir/index.php/aacc/article/view/612
