Use of a Defibrillator
Use of a Defibrillator
(10 True/False questions with explanations).
The early use of a defibrillator gives the victim of a sudden cardiac arrest, the best chance of surviving.
TRUEFALSE
TRUE: Chest compressions and rescue breaths helps to buy the victim some time, but in the vast majority of cases, the heart needs to restart, and to achieve this, the defibrillator is needed.
An untrained person is allowed to use a defibrillator.
TRUEFALSE
TRUE: It is preferable that people are trained in how to use a defibrillator quickly and safely.
Once the defibrillator arrives, do not expose the patient’s bare chest until the set of 30 chest compressions is completed.
TRUEFALSE
FALSE: You need to apply the pads as soon as is possible.
Defibrillator pads can be placed over a bra.
TRUEFALSE
FALSE: The pads must be placed on patient’s bare skin.
Pads need to be placed on to dry skin.
TRUEFALSE
TRUE: If the skin is wet for any reason, even sweat, this must be dried off. Otherwise the shock will go across the wet skin instead of through the heart, and may not be effective.
Basic Life Support can be continued whilst pads are being placed.
TRUEFALSE
TRUE. Continuing to carry out rescue breaths and chest compressions will continue to help push oxygenated blood up to the brain.
Basic Life Support can be continued whilst the defibrillator is analysing the rhythm.
TRUEFALSE
FALSE: Nobody must touch the casualty whilst the defibrillator is assessing the rhythm.
A defibrillator will always deliver a shock.
TRUEFALSE
FALSE: The defibrillator will deliver a shock only if it is appropriate.
A defibrillator reassesses the casualty’s heart rhythm every two minutes.
TRUEFALSE
TRUE: This is also how long each rescuer should be doing Basic Life Support, so use the time when it is analysing to swap positions. If a shock is advised, deliver the shock and then you have someone who has rested, to start Basic Life Support for the next two minutes.
The defibrillator pads should stay in place until an ambulance crew arrives.
TRUEFALSE
TRUE: The defibrillator pads can cope with delivering many shocks. Do not be tempted to remove them.
