Rose’s niece visits

Rose’s niece, Jill, arrives to help her aunt tidy up after breakfast and notices that the curtains are still drawn. She lets herself in through the keysafe and finds her aunt collapsed on the kitchen floor. She immediately calls 999 on her mobile phone and, following the call handler’s guidance, commences CPR.

Examples of how a call-handler guides the CPR process can be heard in the two audio-recordings below:

Although she is very distressed, Jill manages to follow the instructions given to her by the call-handler.

Jill continues to administer chest compressions to Rose until the first responders arrive.

Pulse point

When a call-handler gives CPR instructions over the phone, this is known as Dispatcher-Assisted CPR. Dispatcher-Assisted CPR appears to improve cardiac arrest outcomes. Increased availability and use of mobile phones has made it easier for the rescuer to stay with the person who has had the arrest, whilst receiving instructions.

Ro et al (2017) carried out an interesting research study (Effect of dispatcher-assisted cardiopulmonary resuscitation program and location of out-of-hospital cardiac arrest on survival and neurological outcome) which appeared to show that dispatcher-assisted CPR was more effective than bystander CPR alone when the cardiac arrest occurred in a private setting.

The Resuscitation Council UK Guidelines 2015 point out that, in the UK, call-handlers who answer 999 calls generally have no medical training background. It is essential that they are fully trained in recognising and managing OHCA calls, particularly as they may be dealing with very distressed callers. Following an OHCA call, the call-handler will normally be offered a hot debrief or time out with a supervisor.
