Study Notes
Bag-Mask Device
- Utilized in 2-rescuer Basic Life Support (BLS) for providing positive-pressure ventilation.
- Comprises a bag connected to a face mask; may be self-inflating.
- Functions with or without an oxygen supply; delivers about 21% oxygen when not supplied.
- Some devices incorporate a one-way valve which can differ between models.
Critical Points of Using a Bag-Mask Device
- Operates similarly to a pocket mask.
- Administer 2 breaths after every 30 chest compressions.
- Each breath should last 1 second, providing enough volume for visible chest rise.
- Avoid over-ventilation to ensure effective breathing.
Roles for 2-Rescuer Adult BLS
- First rescuer: responsible for chest compressions, counts out loud, and delivers breaths.
- Second rescuer: activates the AED and attaches the pads.
2-Rescuer Adult BLS Sequence
- Step 1: Ensure scene safety.
- Step 2: Check the victim's responsiveness; if unresponsive, call for help. One rescuer remains with the victim while the other activates emergency response and gets the AED.
- Step 3: Assess for normal breathing and pulse. If normal breathing is present, monitor the victim. If no normal breathing but a pulse is present, provide rescue breathing.
- Step 4: Initiate CPR (30 compressions followed by 2 breaths) if the victim is not breathing and has no pulse. Use AED as soon as it's available.
- Step 5: When the AED arrives, assess the heart rhythm to determine if it is shockable.
High-Quality CPR: Adult
- Key characteristics include compressing the chest hard and fast at a rate of 100-120 compressions per minute with a depth of at least 2 inches.
- Ensure complete chest recoil after each compression; do not lean on the chest.
- Keep interruptions in compressions to less than 10 seconds.
- Deliver effective breaths that achieve chest rise while avoiding excessive ventilation.
