Respiratory rate, end\u2010tidal carbon dioxide (ETCO<jats:sub>2<\/jats:sub>), and time to ETCO<jats:sub>2<\/jats:sub> waveform were recorded.<\/jats:p><\/jats:sec><jats:sec><jats:title>Measurements and Main Results<\/jats:title><jats:p>Mainstream capnography failed to detect an ETCO<jats:sub>2<\/jats:sub> reading or respiratory waveform in all dogs evaluated. In dogs and cats, sidestream capnography accurately detected ETCO<jats:sub>2<\/jats:sub> measurement, respiratory rate, and waveform within 4\u00a0s of feeding tube insertion into the ET tube, with ETCO<jats:sub>2<\/jats:sub> readings &gt;35\u00a0mm\u00a0Hg in all dogs and &gt;20\u00a0mm\u00a0Hg in all cats. ETCO<jats:sub>2<\/jats:sub> readings obtained from the NE tubes were similar to but did not match those obtained by the anesthesia monitoring equipment for dogs and cats. Sidestream capnography accurately detects airway intubation with small\u2010bore, styleted NE tubes in dogs and cats, regardless of patient size. Further studies are required to determine whether this method could be used in awake and sedated patients in real time to detect airway intubation during placement of NE tubes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Sidestream capnography is able to detect misplacement of small\u2010bore, styleted feeding tubes into the respiratory tract of dogs and cats regardless of patient size.
