Capnography and Pulse Oximetry During Ventilation

When a sick patient requires the use of a ventilator to provide enough oxygen to the brain and body, monitoring patient vital signs – especially end-tidal CO₂ (EtCO₂) and pulse oximetry (SpO₂) – becomes even more important. Today, most ventilators are capable of measuring EtCO₂ but in cases where monitors do not include those patient monitoring parameters, a stand-alone device can be used.
