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

15. juli 2026 oppdatert av: Emine Arici Parlak

"The Effect of Pulse Oximeter Probe Replacement Interval on Pressure Injury Development in Intensive Care Patients: A Randomized Controlled Trial"

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.

Studieoversikt

Detaljert beskrivelse

Pulse oximetry is a non-invasive monitoring method that continuously measures arterial oxygen saturation (SpO₂) and pulse rate using optical sensors placed on peripheral tissues. It is widely used in intensive care units (ICUs), operating rooms, and other critical care settings for continuous patient monitoring . Although essential for patient care, prolonged application of pulse oximeter probes to the same anatomical site may increase the risk of medical device-related pressure injuries (MDRPIs), particularly in critically ill patients with impaired tissue perfusion, immobility, and fragile skin.

Medical device-related pressure injuries represent a substantial proportion of hospital-acquired pressure injuries and are associated with increased morbidity, prolonged hospitalization, and healthcare costs. International clinical practice guidelines recommend frequent skin assessment, regular repositioning of medical devices, prompt removal of unnecessary devices, and interventions to reduce pressure. However, these guidelines do not define an evidence-based interval for repositioning pulse oximeter probes, and current clinical practice varies considerably among healthcare institutions.

Several case reports have described tissue injury associated with prolonged pulse oximeter sensor application, including skin erosion and tissue necrosis at the finger, toe, ear, and forehead. Nevertheless, high-quality randomized controlled trials evaluating the optimal pulse oximeter probe replacement interval are lacking.

The primary objective of this randomized controlled trial is to determine whether different pulse oximeter probe replacement intervals influence the incidence of pressure injuries in adult ICU patients. The findings are expected to provide evidence for establishing standardized clinical protocols for pulse oximeter probe repositioning and contribute to the prevention of medical device-related pressure injuries in critically ill adults.

Eksperimentell: Intervention Group
Patients will have a pulse oximeter probe placed on the right index finger. The probe site will remain unchanged for 2 hours. At the end of the 2-hour period, the probe will be removed, and the skin will be assessed for pressure injury using the Skin Assessment Form.
The pulse oximeter probe will be placed on the patient's right index finger and repositioned every 2 hours. After 2 hours, the probe will be removed, the skin will be assessed for pressure injury using the Skin Assessment Form, and the probe will be repositioned according to the study protocol.
Aktiv komparator: Control Group
Patients will receive routine intensive care. The pulse oximeter probe will remain in the same position for 4 hours, consistent with standard ICU practice. At the end of the 4-hour period, the probe will be removed, and the skin will be assessed for pressure injury using the Skin Assessment Form.
The pulse oximeter probe will remain in the same position for 4 hours in accordance with routine intensive care unit practice. After 4 hours, the probe will be removed, the skin will be assessed for pressure injury using the Skin Assessment Form, and routine care will continue.

Tidsramme
Incidence of Medical Device-Related Pressure Injury at the Pulse Oximeter Probe Site
Tidsramme: Up to 4 hours after pulse oximeter probe placement

The primary outcome is the incidence of medical device-related pressure injury (MDRPI) associated with pulse oximeter probe application in adult intensive care unit patients. Skin assessments will be performed using the Skin Assessment Form developed by the investigators based on the literature and the European Pressure Ulcer Advisory Panel (EPUAP) guidelines.

The assessment includes:

Presence or absence of medical device-related pressure injury Non-blanchable erythema Skin moisture Skin integrity Presence and severity of edema Tissue firmness Palpation findings Local skin temperature changes Pressure injury stage (Stage 1, Stage 2, Stage 3, Stage 4, Deep Tissue Injury, or Unstageable)

The incidence of pressure injury will be compared between patients whose pulse oximeter probe is repositioned every 2 hours and those whose probe is repositioned every 4 hours.

Up to 4 hours after pulse oximeter probe placement
