Resus Theory Flashcards
What is the primary purpose of CPR?
To maintain blood flow and oxygenation to the body’s cells during cardiac arrest
CPR helps to preserve brain function and minimize damage until advanced medical help arrives.
What molecule stores energy produced by cellular respiration?
Adenosine Tri Phosphate (ATP)
What is aerobic respiration?
A process where cells use oxygen to generate ATP through the electron transport chain, producing 32 ATP molecules per cycle.
What is anaerobic respiration?
A process that occurs in the absence of oxygen, using the Krebs cycle to produce only 2 ATP molecules per cycle and resulting in lactic acid production.
What must every cell in the body have access to?
ATP and oxygen
What is cardiac arrest?
A condition where the heart stops beating, leading to a cessation of blood flow.
What are the signs that might indicate a cardiac arrest?
Unresponsiveness, absence of breathing, and absence of pulse.
What is the relationship between area and pressure?
As area increases, pressure decreases; as area decreases, pressure increases.
What is the recommended compression rate during CPR?
110 compressions per minute
What is the recommended depth of chest compressions during CPR?
5 cm or 1/3 of the chest depth
What is the function of the Sino Atrial (SA) node?
It originates the electrical impulse for normal sinus rhythm.
What are the characteristics of Ventricular Tachycardia (VT)?
Fast heart rate originating in the ventricles, presenting a shark tooth appearance.
What is Ventricular Fibrillation (VF)?
A disordered electrical activity in the heart where it quivers and produces no pulse.
What is Pulseless Electrical Activity (PEA)?
Organized electrical activity without detectable output; do not defibrillate.
What is Asystole?
Complete absence of electrical activity in the heart; poor prognosis and do not defibrillate.
What distinguishes primary cardiac arrest from secondary cardiac arrest?
Primary cardiac arrest is due to mechanical or electrical failure of the heart; secondary cardiac arrest is due to non-cardiac problems.
What is the CPR compression to ventilation ratio for primary cardiac arrest?
30:2
What is the CPR compression to ventilation ratio for secondary cardiac arrest?
15:2
What is the most important principle of CPR?
High quality chest compressions
What does the ‘Pit Crew Approach’ in CPR emphasize?
Defined roles, clear communication, and flattened hierarchy.
Fill in the blank: The heart runs on _______.
electricity
