CPR

New Tool for CPR Performance Tracking

Now we have a new tool for organisations and companies to keep track of their staff CPR performance. This tool is included in our Risk Management services for corporations to ensure that their staff response to medical emergencies at the workplace is defensible in any court of law.

2 Minutes of CPR after Every AED Shock

It is important that rescuers of cardiac arrest victims provide 2 minutes of CPR after every shock delivered by the AED, according to guidelines provided by the International Liasion Committee on Resuscitation (ILCOR), the European Resuscitation Council (ERC) and American Heart Association (AHA).

The extracted documents with the highlighted statements (3rd page) from the ERC can be found HERE. The flow chart is as follows :

The extracted documents with the highlighted statements (2nd page) from the AHA can be found HERE.

The reasons for this is because pauses to provide shocks is detrimental to the overall outcome, provided the victim is not revived by the first shock.

According to Dr Kramer-Johansen J et al in his paper “Pauses in chest compression and inappropriate shocks: a comparison of manual and semi-automatic defibrillation attempts” published in the journal Resuscitation 2007 May;73(2):212-20, the amount of time chest compression is not done is 22 seconds (median) pre-shock and 20 seconds (median) post-shock.

What this means that in a 5 minute window period of rescue time ( starting with the first shock ) , if rescuers performs chest compression of 2 minutes in between shocks, the total time without compression is 84 seconds, compared to 168 seconds if the interval between shocks is 1 minute.

What this means is that if someone performs 1 minute of CPR in between shocks, the total time of not performing chest compressions, ie not perfusing the vital organs like the brain and the heart itself, is 2.8 minutes out of 5 minutes (56%), compared to 1.4 minute (28%) when the interval is 2 minutes of CPR in between shocks.

Local evidence that 2 minute CPR in between shocks is the right protocol is seen by the experience of one of our clients, who saved a life recently. The story can be found HERE.

However, there is clinical evidence that rescuer fatigue can set in easily, as shown below.

This is the reason why we encourage our clients to pre-plan deployment of teams to all corners of their area of coverage, and to rotate among the rescuers in providing chest compressions, if need be every minute. 5 cycles of 30:2 compressions:ventilation will last approximately 2 minutes.

Only with teamwork will we be able to achieve the best outcomes.

First Documented Life Saved by Our Client

CPR in KPE

CPR in KPE

On 14th September 2008, one of our training partners responded to a collapsed man on an event in the newly completed Kallang-Paya Lebar Expressway. Cardiopulmonary resuscitation (CPR) was commenced first. On their ambulance was the essential automated external defibrillator (AED) that they used on this man.

A total of 3 shocks were given to this man.

The man was described to have turned blue before the device was applied. After the 3rd shock, he slowly turned pink right before their eyes!

The man was then loaded into their ambulance and droved him to the nearby Changi General Hospital. It took them 32 minutes to reach the hospital, a duration that would be certain death for this man if the AED was not used on him.

The AED device had recorded the actual events which unfolded as the rescue was in progress. The reading here is the exact time that this man’s heart was converted from ventricular fibrillation to sinus rhythm. In the next few readings, the rhythm quickened in pace and became more regular. All this occurred while he was transported in our training partner’s ambulance without any infusion or drugs.

The man was subsequently transferred to the National Heart Centre from Changi General Hospital and is currently recovering. We wish him all the best!

This is what we wish to duplicate should any of our family members, friends or neighbours fall victim to such unfortunate incidents. To save our families and friends so that they can continue to be with us.
