Aug 1, 2017 · In this way, low EtCO 2 can help indicate the presence of significant ketoacidosis. 1,8,14 S: Rounded rectangle EtCO 2 waveform. T: Consistent Q, R and S with each breath for hypoglycemia.
5 things to know about capnography and respiratory distress
Oct 3, 2018 · Diabetic ketoacidosis (DKA) may present with difficulty breathing, rapid respiratory rate, and low ETCO2 as the body attempts to compensate for acidosis [1]. Shortness of breath from anxiety-induced hyperventilation is caused by an excess of CO2 exhalation.
Waveform capnography in the intubated patient - EMCrit Project
Aug 5, 2021 · Low etCO2 may be due to suboptimal CPR technique, but it may also be due to death (cessation of cellular respiration, leading to a lack of CO2 production). Most studies have evaluated etCO2 after 20 minutes of CPR:
