The effectiveness of oxygenation and ventilation can be assessed through a combination of pulse oximetry and capnography.

Pulse oximetry is a non-invasive method that measures the percentage of hemoglobin saturated with oxygen in the blood. It provides immediate feedback on how well oxygen is being transported to tissues and whether a patient is adequately oxygenated. A normal pulse oximetry reading typically indicates effective oxygenation.

Capnography measures the concentration of carbon dioxide in exhaled air, providing insight into ventilation effectiveness. It helps to monitor the patient's ventilation status, ensuring that carbon dioxide produced by metabolism is being adequately expelled. This is crucial in various clinical settings, especially in acute care situations where respiratory function may be compromised.

Using both parameters together offers a comprehensive view of a patient's respiratory status, allowing healthcare providers to make timely decisions regarding interventions if needed.
