Monitoring patient's breathing in emergency and critical situations is of paramount importance. Delivering oxygen ensures the level of oxygen saturation in the blood is maintained and this sometimes is monitored and measured by a pulse oximeter. However, the pulse oximeter does not provide breath by breath patient ventilator status. Capnography is the vital sign of ventilation. By tracking the patient's expired CO2 clinicians can evaluate the ventilation condition of the patient during critical emergency situations, and make the judgment to assess and treat the patient.
