Pulse oximetry is useful for screening sleep apnoea syndrome in dialysis patients Sir, Sleep apnoea syndrome (SAS) is characterized by repetitive nocturnal hypoxia, while it is also known to be a risk factor for cardiovascular disease [1]. The prevalence of SAS in dialysis patients has been shown to range from 20 to 50% in comparison to a range of 2–4% in the general population [2,3]. Although ...

Pulse oximetry is a technique for estimating arterial oxygen saturation continuously and non-invasively. Reflectance pulse oximetry might become useful for monitoring the fetus during labour but it is much more susceptible to all kinds of physiological variations than the well-established transmission pulse oximetry for neonatal or adult monitoring. This review focuses on the accuracy of reflec...

OBJECTIVE To undertake a cost-effectiveness analysis that compares pulse oximetry as an adjunct to clinical examination with clinical examination alone in newborn screening for congenital heart defects (CHDs). DESIGN Model-based economic evaluation using accuracy and cost data from a primary study supplemented from published sources taking an NHS perspective. SETTING Six large maternity uni...
