What equipment might be adjusted if a patient experiences distress during therapy?

Adjusting the flow rate of oxygen is crucial when a patient experiences distress during therapy because the flow rate directly affects the amount of oxygen being delivered to the patient. If a patient is showing signs of distress, it could indicate that they are not receiving adequate oxygen, which may necessitate an increase in the flow rate to meet their respiratory needs.

Oxygen therapy aims to maintain adequate oxygen saturation levels in the blood, which is essential for cellular functions and overall health. By adjusting the oxygen flow rate, healthcare providers can quickly respond to the patient's demands and help alleviate distress caused by hypoxia or inadequate oxygenation.

While other options such as humidifier settings and patient positioning may also play roles in a patient’s comfort and overall therapy, they are secondary concerns in an acute situation where oxygen delivery is paramount. Adjusting the device brand generally does not apply to immediate patient care needs and is not a practical option in the context of emergency response to patient distress. Therefore, modifying the flow rate is a direct and effective measure to enhance oxygen delivery and improve the patient's condition.
