// PARAMEDIC Question · Advanced Airway & Ventilation
A patient is intubated and the ETCO₂ waveform is gradually rising. This suggests:
A. Hyperventilation
B. HypoventilationCorrect
C. ET tube dislodgement
D. Cardiac arrest
// Rationale
A rising ETCO₂ trend indicates hypoventilation or increased CO₂ production; increase ventilation rate.
