An unusual explanation for low oxygen saturation.
Pulse oximeters are now commonplace in modern medical practice, but we still need to be aware of their limitations. We present here a case of a 62-yr-old gentleman who underwent general anaesthesia for a recurrent parietal meningioma. He had received multiple general anaesthetics in the past. Persistent low pulse oximetry readings in the perioperative period, without any suggestion of respirato...
متن کاملHypoxia, color vision deficiencies, and blood oxygen saturation.
Chromatic thresholds were measured using the Cambridge Colour Test (CCT), the Colour Assessment and Diagnosis (CAD) test, and the Cone Specific Contrast Test (CSCT) at ground and 3780 m (12,400 ft) for subjects with normal color vision and red-green color vision defects. The CAD revealed a small (~10%) increase in the red-green thresholds for the trichromatic subjects and a similar increase in ...
متن کاملEffects of position on oxygen saturation and heart rate in very low birth weight neonates
Background: Desirable oxygenation of preterm newborns has particular importance, for this reason different methods have been proposed to improve oxygenation of the newborns; one of these methods is the newborns' position. The aim of this study was to determine the effect of the position of low birth weight neonates on arterial oxygen saturation and heart rate. Methods: This interventional st...
متن کاملDiagnostic Dilemma: Low Oxygen Saturation during Cardiac Surgery
We report a case of rheumatic heart disease with severe mitral stenosis having cyanosis and low oxygen saturation on pulse oximetry. The findings of clinical examination and low values on pulse oximetry were inconsistent with the findings of normal partial pressure of oxygen and oxygen saturation on arterial blood gas analysis, leading to diagnostic dilemma. In such clinical scenario, the anest...
متن کاملCause of Low Arterial Oxygen Saturation in Pulmonary Fibrosis.
Since the description of 'alveolar-capillary block' by Austrian, McClement, Renzetti, Donald, Riley, and Cournand (1951), impairment of diffusion across the alveolar-capillary membrane has been regarded as an important factor in the production of low arterial oxygen saturations in patients with diffuse pulmonary disease. However, Luchsinger, Moser, Buhlmann, and Rossier (1957) suggested that re...
