Flashcards in BLS for Adults Deck (13):
What is the ratio of compressions to breaths in CPR?
What are the steps for responding to cardiac arrest?
1) Verify scene safety.
2) Check responsiveness.
3)Shout for help, activate emergency response system, and get or send someone to get AED.
4) Check breathing and pulse for 10 seconds.
What do you do if the patient has no normal breathing, but has a pulse?
Provide rescue breaths, 1 every 5-6 seconds for two minutes, then recheck pulse.
For how long should you check for breathing and pulse?
What kind of breathing may be present in the first minutes following cardiac arrest but is not normal breathing?
Why is allowing complete chest recoil important after each compression?
It allows blood to flow into the heart.
What are two techniques for opening the airway?
1) Head tilt-chin lift
2) Jaw thrust
What percent oxygen is normal air? What percent oxygen is the air we exhale? Why does rescue breathing work?
c) Because we use a relatively small amount of the oxygen we breath in.
Over how much time should each rescue breath be given?
Over one second
How quickly should you resume chest compressions after stopping to give rescue breaths?
Within 10 seconds
What device is used to provide positive pressure ventilation?
What technique allows you to simultaneously hold the mask and lift the jaw?
E-C technique; thumb and index finger form a "C" on the mask, while the three other fingers form an "E" to lift the jaw.
