متن کاملPrediction of the apnea-hypopnea index from overnight pulse oximetry.
STUDY OBJECTIVE s: To compare the relative usefulness of the different indexes derived from pulse oximetry in the diagnosis of obstructive sleep apnea (OSA), and to determine if a combination of these indexes improves the prediction of the apnea-hypopnea index (AHI) measured by polysomnography. DESIGN Prediction model developed from 224 patients, validated prospectively in 101 patients from t...
متن کاملVariations in physician interpretation of overnight pulse oximetry monitoring.
BACKGROUND Overnight pulse oximetry is commonly used for hypoxemia evaluation in patients with COPD and sleep-disordered breathing. There is little information regarding its impact on physician decision making, and therefore an important measure of its clinical utility is untested and unknown. The aim of this study was to describe physician interpretation, use, and opinions regarding overnight ...
متن کاملPulse Oximetry
The principal advantage of optical sensors for medical applications is their intrinsic safety since there is no electrical contact between the patient and the equipment. (An added bonus is that they are also less suspect to electromagnetic interference). This has given rise to a variety of optical techniques to monitor physiological parameters: for example, the technique of Laser Doppler veloci...
متن کاملDiagnosis of PLMD from increased pulse rate variability on overnight oximetry
STUDY OBJECTIVE This study was undertaken in a group of patients with periodic limb movement disorder (PLMD) to assess whether the presence of increased pulse rate variability (PRV) without desaturation on overnight oximetry was suggestive of the occurrence of periodic limb movements (PLMs). METHODS Seventy sleepy patients with a polysomnographic diagnosis of PLMD and 25 controls with obstruc...
