چکیده

The most basic goal of anaesthetists and intensivists is to assure that there is an adequate supply of oxygen to the mitochondria throughout the body to maintain aerobic metabolism and cellular function. The determination of adequate oxygenation has historically been monitored by the absence of organ dysfunction because techniques were not available to assess quantitatively the oxygenation of tissues. Over the past 40 years, measurement and monitoring methods have been developed to first quantitate oxygen supply and more recently to continuously asess both invasively and noninvasively the oxygenation of blood and tissue.’ This article will review the current status of the invasive and noninvasive techniques for monitoring oxygenation.

Brain Oxygenation Monitoring.

A mismatch between cerebral oxygen supply and demand can lead to cerebral hypoxia/ischemia and deleterious outcomes. Cerebral oxygenation monitoring is an important aspect of multimodality neuromonitoring. It is increasingly deployed whenever intracranial pressure monitoring is indicated. Although there is a large body of evidence demonstrating an association between cerebral hypoxia/ischemia a...

Monitoring Oxygenation and Gas Exchange in Neonatal Intensive Care Units: Current Practice in the Netherlands

BACKGROUND Although recommendations in oxygenation and gas exchange monitoring in the neonatal intensive care unit (NICU) are available, little is known of the current practice. AIM To evaluate the current practice in oxygenation and gas exchange monitoring of the NICUs in the Netherlands. METHODS An online survey-based questionnaire concerning preferences and current practice of monitoring...

Perfusion and Oxygenation

Shock occurs when tissue oxygen delivery is inadequate to meet metabolic demands, and cellular dysfunction results. Since a primary goal of treating shock is elimination of cellular hypoxia, it logically follows that detecting and treating shock would best be monitored by measuring the state of tissue perfusion and cellular oxygenation. To this end, many devices that have the capability of moni...

Optoacoustic monitoring of cerebral venous blood oxygenation though intact scalp in large animals

Monitoring (currently invasive) of cerebral venous blood oxygenation is a key to avoiding hypoxia-induced brain injury resulting in death or severe disability. Noninvasive, optoacoustic monitoring of cerebral venous blood oxygenation can potentially replace existing invasive methods. To the best of our knowledge, we report for the first time noninvasive monitoring of cerebral venous blood oxyge...

Monitoring Cerebral Oxygenation in Neonates: An Update

Cerebral oxygenation is not always reflected by systemic arterial oxygenation. Therefore, regional cerebral oxygen saturation (rScO2) monitoring with near-infrared spectroscopy (NIRS) is of added value in neonatal intensive care. rScO2 represents oxygen supply to the brain, while cerebral fractional tissue oxygen extraction, which is the ratio between rScO2 and systemic arterial oxygen saturati...
