Abstract:
In Denmark, capnography is routinely used in monitoring patients with artificial airways. Non-invasive capnography is occasionally used by prehospital providers, but not applied inside hospital walls. Multiple studies illustrate benefits from capnography in non-intubated patients. Non-invasive capnography may reveal altered ventilation in conditions such as opioid-induced respiratory depression and acute dyspnoea, during metabolic acidosis and among patients with seizures and cerebral damage. Implementation requires education, guidelines for inhospital use and financial investment.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
