Abstract / Description of output

Objective – To assess compression rate accuracy amongst veterinarians and registered veterinary nurses (RVNs) without and with an audible aid.
Design – Prospective study with use of a canine CPR manikin.
Setting – Quiet room in small animal hospital.
Subjects – 36 participants (20 veterinarians and 16 RVNs).
Interventions – Each participant completed the first two-minute cycle of chest compressions without an auditory aid on a canine CPR manikin. Each participant was then randomized to one of three auditory aid groups (Group B: Bee Gees ‘Stayin’ Alive’; Group Q: Queen ‘Another One Bites the Dust’ or Group M: Traditional metronome) and then completed a second two-minute cycle of chest compressions with the instruction to synchronize their compression rate with the beat of the auditory aid. An accurate chest compression rate was defined as obtaining a rate between 100-120 compressions per minute (cpm).
Measurements and Main Results – Median cpm administered by participants during Cycle 1 for the 1st minute was 111 (range 88-140) and for the 2nd minute was 107 (range 80-151), with 25/36 (69%) participants obtaining an accurate chest compression rate. Median cpm administered during Cycle 2 for the 1st minute was 110 (range 76-125) and for the 2nd minute was 110 (range 72-125), with 34/36 participants (94%) obtaining an accurate chest compression rate. Participants were more likely to obtain an accurate chest compression rate when an auditory aid was present compared to without (McNemar’s test; p=0.013). Subgroup analysis suggested the auditory aid was beneficial in Group Q and M but not Group B (Kruskal Wallis with Dunn’s post-hoc testing; p=0.014, p=0.0455 and p=0.5637, respectively).
Conclusions – An auditory aid was associated with improved chest compression rate accuracy. However, as the auditory aid was not beneficial for Group B participants, our findings suggest that some some auditory aids are more helpful than others.
