What is the appropriate oxygen treatment plan for a patient with chronic congestive heart failure and resting SpO2 of 89%?

In the context of chronic congestive heart failure (CHF), maintaining adequate oxygen saturation is critical for the patient's overall health. An SpO2 level of 89% indicates that the patient is experiencing hypoxemia, which necessitates intervention to ensure that oxygen levels are sufficient for optimal bodily functions.

Choosing continuous supplemental oxygen is appropriate because it offers a consistent supply of oxygen, which can help alleviate symptoms related to low oxygen levels. Continuous oxygen can assist in reducing the workload on the heart by improving oxygenation, thereby potentially enhancing exercise tolerance and exercise capacity in a patient with CHF.

Additionally, while some patients may only require supplemental oxygen during specific activities, the presence of resting hypoxemia, as indicated by an SpO2 of 89%, suggests that the patient would benefit more from a steady and constant supply rather than intermittent use.

Other options, such as further evaluation, would be necessary if results were inconclusive or if there were additional comorbidities; however, the patient's current oxygen saturation indicates immediate action is needed. Similarly, remaining on room air would not be adequate for managing hypoxemia, and oxygen as needed might not address the ongoing requirement for sufficient oxygenation given the patient's resting saturation.
