An 86-year-old female with emphysema has an initial SpO2 of 92% on home oxygen and is treated with a non-rebreather mask. After achieving an SpO2 of 100% and resolving chest pain, what is the next step?

After achieving an SpO2 of 100% with a non-rebreather mask, the best next step is to switch to a simple face mask. This approach allows for a reduction in the oxygen concentration delivered while still providing supplemental oxygen to the patient.

In this scenario, the patient has already reached the target oxygen saturation level, indicating that her immediate oxygen needs are being met. Moving to a simple face mask maintains supplemental oxygen delivery and avoids the risks associated with abrupt discontinuation of oxygen. The simple face mask typically provides a lower flow of oxygen compared to a non-rebreather, which is particularly important for this patient with emphysema, as over-oxygenation can sometimes lead to respiratory depression.

Other options would not be appropriate for this pathway. Reducing the flow rate to 6 L/min would not provide an adequate or consistent oxygen concentration, and discontinuing oxygen entirely could compromise the patient's respiratory status and lead to desaturation. Transporting her without adjusting the mode of oxygen delivery might not address the potential for long-term oxygen needs, which signifies an incomplete management strategy. Hence, switching to a simple face mask is a balanced approach to continue supporting the patient's oxygenation while preparing for transport.
