High prevalence of abnormal nocturnal oximetry in patients with hypertrophic cardiomyopathy.

Nov 2009 OBJECTIVES: We sought to determine the prevalence of nocturnal oxygen desaturation and obstructive sleep apnea (OSA) in a population of patients with hypertrophic cardiomyopathy (HCM). BACKGROUND: The coexistence of sleep apnea and HCM, 2 common ... Read more...

Misalignment of disposable pulse oximeter probes results in false saturation readings that influence anesthetic management.

30 Oct 2009 We report a small case series in which misaligned disposable pulse oximeter sensors gave falsely low saturation readings. In each instance, the sensor performed well during preinduction oxygen administration and the early part of the case, most ... Read more...

Global oximetry: an international anaesthesia quality improvement project.

29 Sep 2009 Pulse oximetry is mandatory during anaesthesia in many countries, a standard endorsed by the World Health Organization 'Safe Surgery Saves Lives' initiative. The Association of Anaesthetists of Great Britain and Ireland, the World Federation of ... Read more...

Technical information about 'Oximetry'

Definition: The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
