Randomized Controlled Trial Clinical Trial
Use of supplemental oxygen during bystander-initiated CPR.
To evaluate the efficacy of three methods by which rescuers can breathe supplemental oxygen to increase their delivered oxygen concentration (FDO2) during single-rescuer, bystander-initiated CPR. ⋯ The use of supplemental oxygen increases the rescuer's FDO2 during ventilation-only and full CPR without interfering with CPR performance.
