Because of its simplicity and accuracy, continuous pulse oximetry monitoring (SpO2) has proven an invaluable tool in assessing the patient’s oxygenation status in various environments: the emergency department, operating room, critical care unit, recovery, and the ward. Pulse oximetry, including GE HealthCare’s own TruSignal™ technology, is widely used by clinicians in both acute and long-term patient care to determine appropriate interventions when a change in condition occurs.
