Abstract
Objective: During basic life support (BLS) by a two-rescuer-team early defibrillation and ALS procedures should be performed without interruptions of the BLS-ventilation/compression sequence. The objective of this study was to determine the impact of a ventilation/compression ratio of 5:50 versus 2:15 on the time intervals "Start BLS to first shock" and "Start BLS to intubation". Methods: Using a random cross over design 40 experienced paramedics performed a standard BLS/ALS-algorithm according to ILCOR guidelines in a manikin model with ventricular fibrillation performing both the 2:15 and the 5:50 ventilation/compression ratio. In addition paramedics were interviewed about work-flow and emotional stress during the test. Conclusions: The ventilation/compression ratio of 5:50 compared with 2:15 during BLS with unsecured airway reduces the time until first defibrillation and endotracheal intubation is performed without changes in ventilation volume and compressions per minute. The Paramedics stated that the 5:50 ratio improved the work-flow and reduced the emotional stress.
