Abstract

Introduction: Every year approximately 360,000 people die following asphyxial cardiac arrest due to drowning. Effective ventilation by surf lifeguards should be initiated as soon as possible to improve survival. The use of a supraglottic airway (SGA) may help deliver effective ventilations. SGA is widely used by nurse anesthetists as a standard for airway management, but it is unknown whether surf lifeguards, who are often non-healthcare providers, can use SGA effectively. SGA used by nurse anesthetists may be considered as a gold standard. Aim: To compare the use of a SGA by surf lifeguards and nurse anesthetists. Methods: In a simulation study, surf lifeguards without healthcare background and nurse anesthetists were asked to insert a SGA (i-gelO2, size 4, Intersurgical) in a resuscitation manikin (AMBU Man ALS, AMBU) and perform ventilations. Tidal volume was analyzed via manikin software and time to ventilation was analyzed by video recording. A successful ventilation was defined as a volume of 0.5-0.6 L. An effective ventilation was defined as a visible manikin chest rise. Questionnaires on ventilating a manikin vs a patient were distributed to nurse anesthetists. Results: In total, 30 surf lifeguards (70% male, median age: 24 years (Q1;Q3: 21;27), lifeguard experience: 3 years (1;6)) and 30 nurse anesthetists (16% male, median age: 43 years (38;52), clinical experience: median 17 years (13;20)) were included. Mean tidal volume was 0.55 L (SD: 0.21) for surf lifeguards and 0.31 L (0.10) for nurse anesthetists (diff. 0.24, 95% CI 0.32-0.15, p<0.0001). The median time to ventilation was 20 sec. (15;22) for surf lifeguards and 17 sec. (15;21) for nurse anesthetists (p=0.39). Surf lifeguards and nurse anesthetist delivered 100% and 95% effective ventilations respectively (p=0.004) and 19% and 5% successful ventilations respectively (p<0.0001). Nurse anesthetists stated it was easier to ventilate a manikin compared with a patient (57%), while 33% stated no difference, and 10% stated it was easier to ventilate a patient. Conclusions: In a simulated set up, there is no difference between surf lifeguards and nurse anesthetists in time to ventilation. All ventilations were effective in both groups, but surf lifeguards delivered ventilations with higher quality.
