Resuscitation in Cardiac Arrest Flashcards
this focuses on management of the airway, ventilation, and oxygenation, and resstoring adequate circculation.
resuscitation
this occurs when the ventricles of the heart, for any of a variety of reasons, are not contracting or when the cardiac output is completely ineffective and no pulses can be felt. The worst manifestation of cardiac compromise
cardiac arrest
the uncoordinated twitching of the heart is known as
ventricular fibrillation
following cardiac arrest brain cells begin to die within
4-6 minutes
sudden death occurs when a patient dies within
1 hour of the onset of signs and symptoms
what r the 3 phases the patient goes through following cardiac arrest that lead to biological death
electrical pulse
circulatory phase
metabolic phase
this phase begins immediately upon cardiac arrest and ends 4 minutes afterwards. heart still has good supply of oxygen and glucose
electrical phase
this phase begins 4 minutes-10 minutes following CA, during this phase oxygen stores have been exhausted and the myocardial cells shift from aerobic to anaerobic metabolism. results in little energy production, the heart is not prepared for defibrillation and is not prone to restarting
circulatory phase
this phase begins 10 min after cardiac arrest and glucose has large amount of acid build-up. tissues begin to die, sodium attracts water inside the cell which eventually ruptures and dies or leads to organ death
metabolic phase
is from the time the patient goes into cardiac arrest until CPR is effectively being performed
downtime
is the total time from when the patient went into cardiac arrest until you delivered the patient to hospital
total downtime
this occurs when a patient regains a spontaneous pulse during the resuscitation effort, the patient begins to breath on their own
return of spontaneous circulation
in cardiac arrest this is defined as a patient who survives to be discharged from the hospital
survival
is when a EMT witnesses the patient become apneic and pulseless
witnessed to cardiac arrest
when EMT arrives onscene and the patient is already unresponsive
unwitnessed cardiac arrest
