Comparative Study Clinical Trial Controlled Clinical Trial
Modified closed circuit underwater breathing apparatus LAR VII and laryngeal mask airway as adjuncts for dive buddy artificial ventilation.
This study evaluated the feasibility of using the modified semi-closed circuit underwater rebreathing system (URS) LAR VII in connection with a laryngeal mask airway (LMA) as an expedient ventilatory adjunct in an operational setting. Fourteen combat swimmers, unfamiliar with this equipment, underwent cardiopulmonary resuscitation (CPR) mannequin training using these devices. Eighteen subjects, using a standard AMBU bag for ventilation, served as controls. ⋯ After proper training, divers might use a modified URS such as the LAR VII for CPR in connection with a LMA. Lower tidal volumes might prevent gastric inflation. Chest compression should be continued during LMA insertion.
