6.0 Alternate Ventilation and Advanced Airways BLS Practice Quiz

• A. Advanced airways can be placed by any bystander without training
• B. Advanced airways are only available in hospitals
• C. Advanced airways are forbidden during CPR
• D. Advanced airways require advanced training and are placed by trained providers

AHA Part 8 says placing advanced airways requires advanced training and is performed by trained health care professionals.

• A. 1 breath every 6 seconds (10 per minute)
• B. Pediatric rate: 1 breath every 2 to 3 seconds for children and infants
• C. Provide no breaths; the advanced airway delivers oxygen passively
• D. Deliver 1 breath every 3 minutes to avoid hyperventilation

AHA's high-quality CPR table specifies 1 breath every 6 seconds, 10 breaths per minute, for adults with an advanced airway.

• A. Press much harder on the second attempt
• B. Skip the second breath and resume compressions
• C. Repeat the head tilt-chin lift to reopen the airway, then try again
• D. Insert a finger deep into the throat to feel for an obstruction

AHA Part 8 directs the rescuer to repeat the head tilt-chin lift if the chest does not rise, then try again to give a breath that makes the chest rise.

• A. It is always preferred over mouth-to-mouth for adults
• B. When mouth-to-mouth breaths cannot be performed, for example, when the mouth cannot be opened
• C. Only for children who cannot seal their lips
• D. Only for infants, never adults

AHA Part 8 says mouth-to-nose breathing may be used when mouth-to-mouth cannot be performed, for example, if the person's mouth cannot be opened or the rescuer cannot make a good seal.

• A. Cover both the infant's mouth and nose with your mouth, then give a breath
• B. Cover only the infant's nose and seal the mouth
• C. Deliver breaths by blowing on the infant's forehead
• D. An infant cannot receive mouth-to-mouth without a barrier

AHA Part 8 says for infants, you can cover both the mouth and nose with your mouth because of the infant's small face, and give breaths.

• A. Nasopharyngeal airway and oral airway only
• B. Only an endotracheal tube placed by a physician
• C. Pocket mask and face shield only
• D. Endotracheal tube and supraglottic airways

AHA Part 8 lists the endotracheal tube and supraglottic airway devices as examples of advanced airways that require specialized training.

• A. Excess ventilation increases cardiac output and improves survival
• B. Too many breaths only affect blood pressure after ROSC
• C. Extra breaths have no effect on circulation during CPR
• D. Hyperventilation increases intrathoracic pressure, reduces venous return, and decreases cardiac output

AHA warns that hyperventilation during CPR increases intrathoracic pressure, impairs venous return to the heart, and decreases cardiac output during compressions.

• A. Compressions pause every 30 to allow 2 breaths, the same as before the airway
• B. CPR stops entirely until the airway is confirmed secure
• C. Compressions can be continuous without pausing for breaths
• D. Ventilation rate doubles to 20 breaths per minute

AHA Part 8 says that with an advanced airway in place, the Compressor can give continuous compressions without pausing for breaths.
