An educational project to improve knowledge related to pulse oximetry

Area of Science:

• Medical Devices
• Clinical Monitoring
• Respiratory Care

Background:

• Pulse oximetry is a vital noninvasive tool for assessing arterial oxygenation in acutely and critically ill patients.
• Accurate interpretation of pulse oximetry data is crucial for physicians, nurses, and respiratory therapists.
• Existing knowledge gaps necessitate targeted educational interventions.

Purpose of the Study:

• To assess the current level of clinician knowledge regarding pulse oximetry.
• To enhance healthcare professionals' understanding of evidence-based practices for pulse oximetry use and interpretation.

Main Methods:

• A 17-question true-false survey, based on American Association of Critical-Care Nurses guidelines, assessed pulse oximetry knowledge.
• A convenience sample of medical, nursing, and respiratory therapy staff completed the survey pre- and post-intervention.
• The educational program incorporated forums, policy updates, competency checks, and orientation enhancements.

Main Results:

• Initial survey results showed a mean correct answer rate of 66% across 442 participants.
• Respiratory therapists demonstrated higher scores (76%) compared to nurses (64%) and physicians (66%).
• Post-educational program, the mean score significantly increased to 82% (P < .01).

Conclusions:

• The educational initiative effectively improved staff knowledge of pulse oximetry monitoring.
• Evidence-based practice adoption in pulse oximetry is achievable through structured educational interventions.
• Enhanced understanding of pulse oximetry contributes to improved patient management in critical care settings.
