If pulse oximetry is unavailable or unreliable, what management should be provided for oxygen therapy?

The management for oxygen therapy when pulse oximetry is unavailable or unreliable involves providing supplemental oxygen to ensure adequate oxygenation of the patient. The choice of 2-6 liters per minute via nasal cannulae or 5-10 liters per minute via face mask is appropriate because it allows for flexible oxygen delivery based on the patient’s condition and need.

Nasal cannulae at a flow rate of 2-6 liters per minute can provide supplemental oxygen effectively for patients who are able to breathe comfortably and maintain adequate tidal volume. This option is beneficial for those who may need lower levels of oxygen, such as patients with mild respiratory distress or those who are conscious and stable.

On the other hand, a face mask at a higher flow rate of 5-10 liters per minute provides a more significant amount of oxygen, suitable for patients who require more intensive oxygen support. This can include those with moderate to severe respiratory distress where higher delivery of oxygen is crucial for improving their oxygenation status.

Providing supplemental oxygen under these flow rates is crucial to prevent hypoxemia in situations where pulse oximetry cannot confirm oxygen saturation accurately. Monitoring the patient’s wellness and response to the oxygen therapy is essential, especially without pulse oximetry for real-time feedback
