Review questions: CPR

391. What is the value of measuring the quantitative waveform capnography on an intubated patient during CPR?

Therefore, it is reasonable to consider using quantitative waveform capnography in intubated patients to monitor CPR quality, optimize chest compressions, and detect ROSC during chest compressions or when rhythm check reveals an organized rhythm.

392. During CPR the rescuer notices that the patient's PETCO2 increases and remains between 35-45mm Hg.  What might a potential cause of this?

If PETCO2 abruptly increases to a normal value (35 to 40 mm Hg), it is reasonable to consider that this is an indicator of ROSC.

393. What are some advantages of endotracheal intubation during cardiac resuscitation?

Advantages of advanced airway placement include elimination of the need for pauses in chest compressions for ventilation, potentially improved ventilation and oxygenation, reduction in the risk of aspiration, and ability to use quantitative waveform capnography to monitor quality of CPR, optimize chest compressions, and detect ROSC during chest compressions or when a rhythm check reveals an organized rhythm. 

394. What the steps for inserting an LMA?

Deflate the cuff completely

Lubricate the tip of the LMA cuff

Insert the LMA into the posterior pharynx with the opening facing the surface of the tongue.

Inflate the cuff

Secure the LMA tube in place

Ventilate the patient

395.  What is a nasopharyngeal airway used for?

Nasopharyngeal airways – also known as nasal trumpets- are airways devices that are inserted through one nostril to create an air passage between the nose and the nasopharynx.
