Week 3 Flashcards
Name some of the cause of cardiac arrest include?
Abnormal cardiac rhythms, cardiomyopathy,
coronary heart disease, myocardial infarction and hypoxia
What are the external causes for cardiac arrest?
External causes can include catastrophic haemorrhage, electrocution and overdose.
What are the chances of survival in a out of hospital cardiac arrest?
> 1 in 10
What is the chain of survival?
Early recognition & 999
Early CPR
Early Defib
Post Resus
What % of cardiac arrests die before they reach hospital?
70-90%
What are the two main components of BLS?
Chest Compressions and Ventilations
Why is high-quality BLS crucial for out-of-hospital cardiac arrest?
It allows us to significantly vary intrathoracic pressure, stimulating blood flow and gas exchange in the lungs, heart, and brain.
What is the primary goal of CPR?
To keep the brain and cells oxygenated by keeping blood moving around the body.
What is the negative impact of pausing chest compressions?
Creates perfusion of the major organs to decrease
What is the correct hand position for chest compressions?
Place the heel of one hand in the centre of the chest, between the nipples. Then, place your other hand on top of the first hand and interlock your fingers.
What are the primary reasons for interruptions during CPR in the pre-hospital setting?
delivering ventilations, analysing rhythms, delivering shocks, moving patients, extricating, CPR during conveyance
How do interruptions in chest compressions affect coronary perfusion pressure and myocardial blood flow?
It can significantly reduce coronary perfusion pressure (CPP) and myocardial blood flow
What are the 5 P’s?

PLAYTEX
PERSPIRATION
PACEMAKER
PENDANTS
What is the Defib patch placement
PAD 1 - right side. Below the clavicle on 2nd intercostal space
PAD 2 - mid-axillary line (middle of armpit) 5th intercostal space (level with the V6 ECG
electrode position)
