Cardiopulmonary Resuscitation Quality by Helicopter Rescue Swimmers While Flying.

OBJECTIVE: Our objective was to assess the cardiopulmonary resuscitation (CPR) quality by helicopter rescue swimmers (HRSs) while flying.

METHODS: Twenty HRSs from the Spanish Maritime Safety took part in this study. The research protocol included 2 phases: a baseline test (5 minutes of CPR on land) and a challenge test (5 minutes of CPR on a Sikorsky S-61N helicopter in-flight). A Laerdal Resusci Anne mannequin with Laerdal PC Skill Reporting (Stavanger, Norway) was used to register CPR variables.

RESULTS: CPR quality on land versus in-flight was not significantly different. The mean chest compression (CC) depth (52.6 mm on land vs. 51.9 mm in-flight) was inside the recommended range, but mean CC rate (133 vs. 132 per minute), tidal volume (752 vs. 888 mL), and hands-off time (9 per cycle in both tests) were above the 2015 recommended goal. Incomplete chest re-expansion was observed in 19% of on land and 26% in-flight CCs. CPR quality was maintained throughout the 5-minute challenges.

CONCLUSION: HRSs are able to perform CPR in a flying helicopter with similar quality to CPR on land. They need additional training to avoid excessive CC rates, tidal volumes, and hands-off times and to permit chest re-expansion.
