The presence of a capnography waveform with a noticeable dip indicates what?

A noticeable dip in the capnography waveform typically indicates a disruption in the airway or respiratory system, often suggesting patient disconnection. This event can occur when the patient becomes disconnected from the ventilatory circuit or endotracheal tube. The dip represents a temporary cessation of CO2 exhalation due to the interruption, highlighting how crucial continuous monitoring is during respiratory support.

In contrast, normal respiratory function would usually show a consistent wave pattern with a smooth rise and fall, reflecting proper CO2 removal. Effective capillary perfusion is generally indicated by stable waveforms, as it demonstrates that the blood is adequately carrying CO2 to the lungs for exhalation. Hypercapnia, or elevated levels of carbon dioxide, would result in a sustained increase in the CO2 readings on the capnography, rather than a dip, hence not aligning with the indicated waveform change.
