Resus Flashcards
Diastole
Part of the cardiac cycle when the heart is relaxed (filling phase)
Hypovolaemia
Low blood volume
Hypoxia
Low oxygen levels at tissue
Primary Cardiac arrest
The cardiac arrest is clearly caused by a CARDIAC problem and no other cause
Eg= Arrhythmia (VT,VF)
Myocardial infarction (MI)
HP-CPR
Prognosis
The likely outcome of medical conditions
Pulmonary thrombosis
A blood clot that occluded the arteries of the lung
R49
Radio code for confirmed cardiac arrest
ROSC
Return of spontaneous circulation, post arrest return of observable circulation
Secondary Cardiac arrest
A Cardiac arrest with NO obvious cardiac cause
Eg asthma, drowning, trauma, poisoning (OD)
SCA
Sudden cardiac arrest
Sudden, and often unexpected, loss of cardiac output
Systole
The part of the cardiac cycle when the heart is contracted( pumping phase)
Leading cause of SCA?
Cardiac diseases cause most SCA ,Coronary Artery’s disease is most prevalent
Electrical phase of cardiac arrest?
First 4 mintues of SCA, when the least amount of damage has been done to the body and treat is more likely to be successful
Circulatory phase of cardiac arrest?
4-10min after SCA, harmful amounts of Lactic acid accelerates the rate of damage and cell death, successful defibrillation relies on high quality chest compressions to delay lactic acid effect
Metabolic phase of Cardiac arrest
10min+ oxygen starts to run out cause possible brain damage cell death becomes irreversible along with the accumulation of lactic acid death is the most likely out come
