Resuscitation
- DRS ABCD
It is now required that
all UK general practitioners and their staff undergo an annual
refresher course in CPR (cardiopulmonary resuscitation) and
defibrillation. The British Heart Foundation is funding the
widespread availability of defibrillators in public places. The
combined benefits of lay training and easy-to-use equipment have
become overwhelming - near my wife's practice in NE England over
the past few years, two patients were revived successfully by trained
receptionists using an automatic external defibrillator. These two
people would have died without the intervention of the non-medical
staff who had received training and who had access to a
defibrillator.
MCA approved medical
training courses provide yachties with a similar training which could
be life saving either at sea or on land. The resuscitation guidelines
are under regular review and the MCA courses follow the UK
Resuscitation Council guidelines which are in line with European
Resuscitation Guidelines.
The acronym in the
title is meant to be a helpful framework to organise an effective
response in the tense moments when a person has collapsed and is near
death. On approaching the casualty it is important to ensure that the
rescuer or the casualty is not at risk of Danger from, for example,
electric faults, sharp objects, toxic spillages. At the same time the
rescuer is making an assessment of the casualty's Responsiveness by
shouting at them or eliciting a Response in some other way by, for
example, inducing slight pain by rubbing knuckles on the breast bone
or squeezing an ear lobe and is also Shouting for assistance. On
board ship, it is good practice to have a drill which ensures that
anyone calling for "medical help", and giving their location, can
rely on a fellow crew member to go for the grab bag, oxygen and
defibrillator and bring it quickly to the location.
For a few vital moments
before this help arrives, the first person on the spot is in the
driving seat and must make a basic assessment of the casualty. The
Airway may be blocked by the tongue or by another obstacle such as
food, seaweed, or false teeth. Bending the neck back will relieve
obstruction from the tongue and a sweep of a finger can remove
obstructing material. In some situations this may be enough to
restore normal breathing and recovery. In a serious collapse, for
instance following a heart attack, the open airway will not be
sufficient and Breathing may still be absent when assessed by placing
one ear near the mouth of the casualty and listening for breath
sounds or feeling expired air on the cheek or seeing the chest rising
and falling with successive breaths. This careful assessment of
possible Breathing should continue for up to ten seconds before
concluding that Breathing has ceased.
If normal Breathing is
absent then chest Compressions should be started in order to squeeze
the heart and pump blood around the body, most importantly to the
brain. The rescuer kneels by the side of the casualty and places the
heel of one hand in the centre of the chest and the heel of the other
hand on top of the first with the fingers interlocked. The rescuer
keeps straight arms and rocks forward to achieve 4-5cm compression at
the rate of 100 compressions per minute. After 30 compressions the
rescuer provides two rescue breaths by maintaining the open airway,
pinching the nostrils and placing lips around the mouth of the
casualty then blowing into the mouth whilst watching the chest rise.
After a second rescue breath the rescuer returns to chest
Compressions and maintains this ratio of 30 to 2 until further help
arrives with the Defibrillator.
Modern Defibrillators
have a built-in instruction commentary and are easy and safe to use.
They produce an electric shock across the heart, which may correct
the chaotic rhythm in a collapsed person who is unResponsive and is
not Breathing. Up to the point that the Defibrillator is applied, the
casualty is simply being kept in a viable condition and the corrected
heart beat produced by a successful Defibrillation gives the best
chance of recovery. The combination of compressions and rescue
breaths is known as cardio-pulmonary resuscitation (CPR) but is not
likely on its own to lead to recovery. It is a holding operation
until the Defibrillator arrives and it is for this reason that
Defibrillators are increasingly available in the community and also
on sailing craft.
European resuscitation
guidelines were last overhauled in 2005 and this affects things like
the ratio of compressions to rescue breaths, the place of rescue
breaths, the checking for neck pulses and the positioning of the
hands on the chest. There are still some variations when compared
with North American or Australian guidelines but in the land of the
blind, the one-eyed man is king – in a near-death collapse,
something is better than nothing – even the best-trained rescuer
can be forgiven a little panic and a little confusion and a little
variation on the international guidelines if the end result saves a
life which would otherwise be lost because of lack of any training.
