Quality of chest compressions during 10Â min of single-rescuer basic life support with different compression: ventilation ratios in a manikin model

Increasing the C:V ratio increases the number of chest compressions during 10 min of BLS. Compression depth and compression rate were within guideline recommendations for all three ratios. We found no decline in chest compression quality below guideline recommendations during 10 min of BLS with any of the three different C:V ratios.
