RECOVER Guidelines Flashcards
How often should CPR training be repeated
Every 6 months
How long should be spent on assessing ABC in unconscious, non-anesthetized patient before initiating compressions?
No more than 10-15 seconds
What are the two goals of chest compressions?
Restoration of pulmonary CO2 elimination & oxygen uptake by providing pulmonary blood flow
Delivery of oxygen to tissues to restore organ function and metabolism by providing systemic arterial blood flow
If giving well executed compressions, how much cardiac output is restored?
About 30%
What is the depth of chest compression recommended by the RECOVER guidelines?
1/3 - 1/2 width of chest
How long does it take for myocardial perfusion pressure to maximize?
About 60 seconds of quality chest compressions
How long can breaks in compression last between rescuers?
2-5 seconds
Cardiac pump theroy
Direct compression of left and right ventricles increases ventricular pressure to lungs and tissues
Thoracic elastic recoil occurs between compressions, allows intrathoracic pressure to draw blood into ventricles
Thoracic pump theory
Vacuum of chest and intrathoracic pressure causes blood to be forced from lungs, through heart, and into systemic circulation
In a multiple rescuer situation, how many breaths should be administered per minute, according to RECOVER guidelines?
10 breaths per minute (1 every 6 seconds)
In a multiple rescuer situation, what is the inspiratory time for each breath, according to RECOVER guidelines?
1 second
In a multiple rescuer situation, what tidal volume should be used for each breath, according to RECOVER guidelines?
10mL/kg
In a single rescuer situation or if intubation is impossible, what is the compression to ventilation ratio, according to RECOVER guidelines?
30 compressions with 2 short breaths in between
Why is it important to avoid hyperventilation?
Decreased cerebral blood flow means hyperventilation must be avoided to maintain cerebral oxygenation
Why do the RECOVER guidelines utilize a low tidal volume and short inspiratory time?
To reduce intrathoracic pressure and improve venous return to the chest - ultimately improves cardiac output
