Pulse oximetry is the mainstay of patient oxygen monitoring. Measurement error from pulse oximetry is more common for those with darker skin pigmentation, yet this topic remains understudied, and evidence-based clinical mitigation strategies do not currently exist. Our objectives were to measure the rate of occult hypoxemia, defined as arterial oxygen saturation (SaO2 ) < 88% when pulse oximeter oxygen saturation was between 92-96%, in a racially diverse critically ill population; to analyze degree, direction, and consistency of measurement error; and to develop a mitigation strategy that minimizes occult hypoxemia in advance of technological advancements. ⋯ Measurement error in pulse oximetry is common for all racial groups, but occult hypoxemia occurred most commonly in Black subjects. The highly variable magnitude and direction of measurement error preclude an individualized mitigation approach. In advance of technological advancements, we recommend targeting a pulse oximetry saturation goal of 94-98% for all patients.

The act of withdrawing advanced life-sustaining therapies, more specifically mechanical ventilation, is performed in hospitals all over the world. Success involves coordination of several members of the patient care team, including nurses, providers (physicians nurse practitioners, or physician assistants), and respiratory therapists (RTs). The experiences of RTs surrounding this procedure are not well documented. The aim of this study was to explore the lived experience of RTs who have participated in withdrawal of advanced life-sustaining therapies, utilizing a hermeneutical phenomenological approach. ⋯ Through this study, the role of RT in withdrawal of advanced life-sustaining therapies is better understood, which can only lead to improvement in the overall process for health care team, patient, and families.
