Pulse oximetry provides continuous or spot checks of oxygen saturation using photoplethysmography. It became standard in perioperative and critical care monitoring and is widely used for respiratory assessment. Sensors attach to finger toe or earlobe and devices display SpO2 and pulse rate with waveform quality indicators.
Pulse oximeters are rapid screening tools for hypoxemia but require clinical correlation and awareness of limitations. Portable sensor based device for monitoring oxygen saturation and pulse rate at the bedside. Ensure proper sensor placement avoid motion artifact and interpret values in clinical context with perfusion and hemoglobin considerations.
