Oxygen saturation targets in COPD focus on keeping SpO2 in a narrow window to balance preventing hypoxemia with avoiding oxygen-induced CO2 retention. The standard target is 88% to 92%. An SpO2 of 89% sits right in that range, so the statement is true. In practice, clinicians adjust supplemental oxygen to stay within this window using pulse oximetry; readings below 88% indicate a need for more oxygen, while readings above 92% suggest reducing oxygen to minimize the risk of hypercapnia. The target isn’t limited to rest or contingent on tolerance—the goal is to maintain the range across activities unless a clinician specifies a different target for that patient.
