While working in the NICU with a mechanically ventilated newborn who is being monitored for PetCO₂,the therapist observes the following capnogram:  What interpretation should the therapist make of this capnogram?

Quizplus · Accepted Answer

Rebreathing is characterized by an elevation in the A-B phase of the capnogram, with a corresponding increase in ETCO₂ . It indicates the rebreathing of previously exhaled carbon dioxide. Rebreathing can be caused by allowing an insufficient expiratory time or by inadequate inspiratory flow (see Figure 9-7 in the textbook).
