Arterial desaturation dependent on posture.
A 60-year-old woman developed subacute bacterial endocarditis following a minor operation. She presented the unusual picture of breathlessness with cyanosis related to posture, confirmed by laboratory measurement. She had an atrial septal defect with right-to-left shunt, and had sustained multiple pulmonary infarcts, resulting iin the obliteration of a large section of her pulmonary vascular be...
متن کاملArterial oxygen desaturation during esophagogastroduodenoscopy.
This prospective study evaluated the incidence and severity of arterial oxygen desaturation during esophagogastroduodenoscopy (EGD) and assessed clinical factors in relation to arterial oxygen desaturation. Following pulmonary function testing, 192 patients underwent elective EGD with continuous recording of arterial oxygen saturation (SaO2). 62 patients (32.3%) showed arterial oxygen desaturat...
متن کاملRate dependent influence of arterial desaturation on self-selected exercise intensity during cycling
The purpose of this study was to clarify if Ratings of Perceived Exertion (RPE) and self-selected exercise intensity are sensitive not only to alterations in the absolute level of arterial saturation (SPO2) but also the rate of change in SPO2. Twelve healthy participants (31.6 ± 3.9 y, 175.5 ± 7.7 cm, 73.3 ± 10.3 kg, 51 ± 7 mL·kg-1·min-1 [Formula: see text]) exercised four times on a cycle ergo...
متن کاملArterial oxygen desaturation after induction of anesthesia.
To the Editor:—Naguib et al. have presented a clinically relevant study of arterial saturation values after preoxygenation and different doses of suxamethonium, and discuss their results using the extensive reports relevant to this topic. Unfortunately, they perhaps did not search the published work back to times before the pulse oximeter was introduced. Before the pulse oximeter, the Hewlett P...
متن کاملCyanosis as a Guide to Arterial Oxygen Desaturation
It is known that the presence or absence of cyanosis of warm parts is some guide to the level of arterial oxygen saturation. Comroe and Botelho (1947) exposed the limitations of cyanosis as a sign, but their observations were made in bright light on normal subjects, who inhaled decreasing percentages of oxygen in nitrogen. Some sites commonly used for the detection of central cyanosis, such as ...
