title: A Novel Use of a Metronome in Dispatcher-assisted Cardiopulmonary Resuscitation.
abstract: Abstract Early, high-quality cardiopulmonary resuscitation (CPR) is the key to increasing the likelihood of successful resuscitation in cardiac arrest. The use of dispatch-assisted (DA) CPR can increase the likelihood of bystander CPR. We describe a case in which a metronome was introduced to guide DA-CPR. The wife of a 52-year-old male activated 9-1-1 after her husband suffered a cardiac arrest. During her 9-1-1 call she received CPR instructions and heard a metronome over the phone while following the instructions. Return of spontaneous circulation of the patient occurred during paramedic on scene care. The patient was transported to hospital and discharged 6 days later with no neurological deficit. This case supports the use of a metronome by emergency medical dispatchers during the provision of DA-CPR to improve bystander CPR.
