Evaluation of Reliability and Validity of Reflectance Pulse Oximeter in Screening Children With Obstructive Sleep Apnea

Polysomnography (PSG) has some disadvantages, such as time-consuming, effort-consuming, long appointment time and high cost. During PSG examination, multiple sensors need to be placed in the patient's head, face, neck, chest and limbs, and sensors are needed to monitor data throughout the night. It is difficult for young children to cooperate, and it is easy to fail due to inaccurate sensor signal acquisition. PSG examination may miss diagnosis or underestimate the disease due to the first night effect. Based on the above reasons, the application of PSG in clinic, especially in pediatric patients is limited. The reflective optical path detection can be used to measure the peripheral blood oxygen saturation in the flat part of human skin. The investigators intend to use a reflectance pulse oximeterto evaluate its reliability and validity in the diagnosis of OSA in children at the same time as PSG.
