Blood oxygenation and spurious hypoxemia
نویسنده
چکیده
In health pO2(a) is maintained within the range 10.613.3 kPa (80-100 mmHg) and hypoxemia (reduced blood oxygen) is diagnosed if pO2(a) is less than 10.6 kPa (80 mmHg). The purpose of this article is to highlight the spurious severe hypoxemia that occurs in patients with particularly high white-cell count or high platelet count. In these patients there is a marked discrepancy between measured (in vitro) pO2(a) and true (in vivo) pO2(a).

Severe hypoxemia during veno-venous extracorporeal membrane oxygenation: exploring the limits of extracorporeal respiratory support
OBJECTIVE Veno-venous extracorporeal oxygenation for respiratory support has emerged as a rescue alternative for patients with hypoxemia. However, in some patients with more severe lung injury, extracorporeal support fails to restore arterial oxygenation. Based on four clinical vignettes, the aims of this article were to describe the pathophysiology of this concerning problem and to discuss pos...

Introduction: Arterial hypoxemia is one of the main pulmonary complications after coronary artery bypass graft surgery. Therefore, several proceedings have been recommended to reduce the complications, and to improve arterial hypoxemia as well as arterial blood gas parameters such as incentive spirometry. This study intended to investigate the effect of incentive spirometry on patients´ oxygen...

Background : Neonatal period is one of the most important periods in human's life. Low birth weight and immaturity is often the cause of death. (weight less them 1000grm and pregnancy less than 30 weeks). One of the main cause of death in this period is respiratory distress syndrome. Objective : To determine the effect of prone and supine positioning oxygenation in preterm infants with resp...

Position changing with blood distribution to different portions of lung can produce V/Q mismatch, and finally extend to oxygenation disruption. Thus, if position changing is done’ neglecting the patients’ pulmonary problem types, not only does it fail to cause oxygenation improvement, but it also induces gas exchange im...
متن کاملHypoxemia During Extreme Hyperleukocytosis: How Spurious?
BACKGROUND Spurious hypoxemia has been described in case reports during extreme hyperleukocytosis and has led to recommendations for immediate cooling and analysis of arterial blood gases (ABGs). We sought to determine, in samples processed as recommended, the magnitude of spurious hypoxemia in acute leukemia subjects with hyperleukocytosis. METHODS A retrospective chart review was conducted ...
