The Effect of Pulse Oximeter Probe Replacement Interval on Pressure Injury Development in Intensive Care Patients

Patients admitted to intensive care units (ICUs) are at increased risk of medical device-related pressure injuries (MDRPIs) due to the prolonged use of monitoring devices. Pulse oximeter probes are routinely used for continuous monitoring of oxygen saturation and pulse rate and may contribute to pressure injury development when left in the same position for extended periods . Current international guidelines recommend regular assessment of the skin and repositioning of medical devices but do not specify an optimal repositioning interval. This randomized controlled trial aims to evaluate the effect of different pulse oximeter probe replacement intervals on the development of pressure injuries in adult ICU patients. The findings are expected to provide evidence to guide clinical practice and improve the prevention of medical device-related pressure injuries.

Inclusion Criteria: * Adults aged 18 years or older * Written informed consent provided by the patient's legally authorized representative * Patients monitored with a pulse oximeter in the intensive care unit (ICU) * Glasgow Coma Scale (GCS) score of 8 or less * Expected or actual ICU stay of more than 72 hours Exclusion Criteria: * Patients with severe peripheral edema * Patients with dermatological conditions that impair skin integrity
