Summer Clinical Practice Test

In COPD, oxygen targets are kept a bit lower to avoid unintentionally suppressing the drive to breathe while still preventing hypoxemia. The commonly used goal is to maintain SpO2 in the 88–92% range. If a patient on supplemental oxygen has an SpO2 of 92%, that sits at the upper end of this target and indicates the current oxygenation goal is being met within the COPD-specific range. It’s not necessary to push toward normal 96–98% in this setting, because that could increase the risk of CO2 retention and hyperoxia-related complications. The reading shows oxygenation status as intended by COPD management guidelines, and you would continue the current oxygen therapy unless orders specify a different target.
