Which resuscitation adjunct corresponds to oxygenation and ventilation analysis (pulse oximetry/ETCO2/capnography)?

• A. N
• B. L
• C. O
• D. P

Answer: (A)

Oxygenation and ventilation analysis is provided by noninvasive monitoring that tracks how well oxygen is being carried in the blood and how effectively CO2 is being eliminated. Pulse oximetry measures arterial oxygen saturation (SpO2) and heart rate, giving real-time info on oxygen delivery to tissues. Capnography or end-tidal CO2 monitoring shows the amount of CO2 being exhaled and provides a waveform; this reflects ventilation and circulation, helps confirm airway placement, gauges the effectiveness of chest compressions, and can indicate return of spontaneous circulation (ROSC) when ETCO2 rises. Because these tools give direct feedback on oxygenation and ventilation during resuscitation, they’re the primary adjuncts used to analyze and guide those functions. Other adjuncts address different aspects of resuscitation and don’t provide the same real-time oxygenation/ventilation data.
