Describe the head tilt-chin lift maneuver and when it is used.
Press to flip
It is used to open the airway in non-traumatic patients by tilting the head backward and lifting the chin.
What is the ratio of compressions to breaths in one-rescuer adult CPR?
30 compressions to 2 ventilations (30:2 ratio).
What is the recommended position for performing effective CPR?
Supine position on a firm surface.
How long can the brain be without oxygen before brain damage is likely?
4-6 minutes.
What are the three key steps in CPR?
High-quality chest compressions, opening the airway, and rescue breathing (2 breaths over 1 second).
What technique should be used to open the airway of a patient with potential trauma?
Jaw-Thrust Maneuver.
For how many seconds should responsiveness and pulse be assessed in a patient?
Within 10 seconds
What makes pediatric BLS different from adult BLS?
In children and infants, respiratory issues often lead to cardiac arrest, whereas in adults, cardiac issues often precede respiratory arrest.
What circumstances justify stopping BLS efforts according to the mnemonic STOP?
Starts breathing/pulse, Transferred to higher training, Out of strength, Physician's direction.
What is the difference between BLS and ALS?
BLS is basic care involving non-invasive procedures, while ALS includes advanced procedures such as cardiac monitoring, IV fluids, medications, and advanced airway adjuncts.
What is the primary focus of BLS?
Non-invasive, life-saving care for airway obstructions, respiratory and cardiac arrest.
What should be the initial action prior to starting BLS?
Survey the scene for safety.
When should an AED be applied to a child in cardiac arrest?
After the first 5 cycles of CPR, if pediatric size pads are available.
What does the CAB sequence stand for in BLS procedures for cardiac risk patients?
Compressions, Airway, Breathing.
What is the technique for performing CPR on infants when there are two rescuers?
Use the two-thumb encircling technique for chest compressions.
