Which LMNOP letter is associated with oxygenation and ventilation analysis?

• A. L
• B. N
• C. O
• D. P

Answer: (B)

In LMNOP, the part that focuses on oxygenation and ventilation analysis is the component that guides you to assess how well gas exchange is happening. This means quickly evaluating oxygen delivery and the effectiveness of ventilation by checking SpO2, using capnography to confirm ventilation (end-tidal CO2), watching for adequate chest rise and breath sounds, and noting work of breathing. If hypoxemia or inadequate ventilation is found, you move promptly to appropriate respiratory support—supplemental oxygen, airway adjuncts, bag-valve-mask ventilation, or advancing to definitive airway management as needed. The other components address different tasks in the resuscitation sequence, but they don’t center on the real-time analysis of oxygenation and ventilation as this step does.
