What is a recommended intervention for maintaining the patient's SpO2 at 94% to 99% in Mr. Hernandez?

Maintaining a patient's peripheral oxygen saturation (SpO2) at an optimal range of 94% to 99% is crucial for adequate oxygen delivery to tissues. Minimal supplemental oxygen is often recommended because it allows the patient to receive just enough oxygen to keep their SpO2 within the desired range without causing potential complications associated with excessive oxygen use.

Excessive oxygen levels can lead to oxygen toxicity, especially in patients with conditions such as chronic obstructive pulmonary disease (COPD), where their drive to breathe may be dependent on lower oxygen levels. By providing minimal supplemental oxygen, clinicians can help prevent risks associated with hyperoxia while still ensuring that oxygen saturation remains within safe limits for the patient's health.

Other interventions, such as high-flow oxygen, CPAP therapy, and mechanical ventilation, may be appropriate in specific clinical situations but could be considered excessive or inappropriate for simply maintaining SpO2 levels within the given range. High-flow oxygen can provide more than what is necessary for this patient, while CPAP therapy is used primarily for respiratory distress or obstructive sleep apnea, and mechanical ventilation is reserved for patients who cannot maintain their own ventilation. Thus, utilizing minimal supplemental oxygen effectively balances safety and efficacy for Mr. Hernandez.
