Pulse oximetry has become a cornerstone technology in healthcare, providing non-invasive monitoring of oxygen saturation levels and pulse rate. Despite its widespread use, the technology has inherent limitations and challenges that must be addressed to ensure accurate and reliable patient care.
To comprehensively evaluate the advantages, limitations, and challenges of pulse oximetry in clinical practice, as well as to propose recommendations for opti
A systematic literature review was conducted to identify studies related to pulse oximetry and its applications in various clinical settings. Relevant articles were selected based on predefined inclusion and exclusion criteria, and data were synthesized to provide a comprehensive overview of the topic.
Pulse oximetry offers numerous advantages, including non-invasiveness, real-time feedback, portability, and cost-effectiveness. However, several limitations and challenges were identified, including motion artifacts, poor peripheral perfusion, ambient light interference, and patient-specific factors such as skin pigmentation and hemoglobin variants. Recommendations for optimizing pulse oximetry use include technological advancements, education and training initiatives, quality assurance protocols, and interdisciplinary collaboration.
Pulse oximetry is crucial in modern healthcare, offering invaluable insights into patients’ oxygenation status. Despite its limitations, pulse oximetry remains an indispensable tool for monitoring patients in diverse clinical settings. By implementing the recommendations outlined in this review, healthcare providers can enhance the effectiveness, accessibility, and safety of pulse oximetry monitoring, ultimately improving patient outcomes and quality of care.
Core Tip: For clinicians utilizing pulse oximetry in practice, it’s essential to remember several key considerations. Firstly, ensure proper sensor placement on well-perfused areas. Minimize motion artifacts by securing the sensor snugly but not too tightly. Establish baseline oxygen saturation levels and consider patient-specific factors like age and medical conditions. Continuous monitoring is crucial in high-risk patients. Regularly maintain and calibrate equipment, replacing sensors as needed. Educate caregivers on the importance of pulse oximetry and proper usage. Lastly, readings should be accurately documented in patient records. By adhering to these core tips, healthcare providers can optimize the effectiveness of pulse oximetry monitoring and enhance patient care.
