For a person in respiratory distress, what indication would suggest that the flow rate of oxygen needs to be increased?

One key indicator that suggests the flow rate of oxygen needs to be increased is when the person's SpO2 drops below 90%. The SpO2 level, or peripheral capillary oxygen saturation, measures the amount of oxygen in the blood. Normal SpO2 levels typically range from 95% to 100%, and values below 90% indicate that the body may not be receiving adequate oxygen, which can lead to serious complications.

When SpO2 levels fall below this threshold, it is crucial to assess and adjust the oxygen supply to the individual, as insufficient oxygenation can result in hypoxia, greatly affecting vital organ function. Increasing the oxygen flow rate is a direct response to improve oxygen saturation and support the individual’s respiratory distress.

While factors like the inflation of a reservoir bag, excessive sweating, or complaints of chest pain can indicate issues related to respiratory distress or overall health, these are not as definitive as a drop in SpO2 for indicating the immediate need to increase oxygen flow.
