The capnography waveform depicts the concentration of CO2 in the breath and has a generally uniform square-like morphology with consistent frequency. In this video, we look at what normal respiratory rates and waveforms look like for healthy patients. US-PM-2200560...
In summary, the study provides preliminary data showing that ETco(2) potentially can be used in continuous monitoring of OSA patients. And, (T - W) ETco(2) can indicate the severity of OSA.

Our experiences as EMS providers with sick children are too few to build real comfort and providers never want to see kids suffering. Nonetheless we do treat sick kids and for children with respiratory distress it’s easy to be confused by lung sounds, especially wheezes. Read Pediatric Wheezing: It’s Not Always...
Objective:
Waveform capnography use has been incorporated into guidelines for the confirmation of tracheal intubation. We aim to describe the trend in waveform capnography use in emergency departments and PICUs and assess the association between waveform capnography use and adverse tracheal intubation–associated...
In our preliminary study, etCO(2) using a microstream method does not seem to accurately predict Paco(2) in patients presenting to an ED for acute dyspnea.
In adults receiving ED propofol sedation, the addition of capnography to standard monitoring reduced hypoxia and provided advance warning for all hypoxic events.
End tidal carbon dioxide tension (P(ET,CO(2))) is a surrogate for dead space ventilation which may be useful in the evaluation of pulmonary embolism (PE). We aimed to define the optimal P(ET,CO(2)) level to exclude PE in patients evaluated for possible thromboembolism.
