Pulse oximetry artefact during laparoscopic surgery

Cerebral oximetry and laparoscopic surgery

Laparoscopic surgery, although enjoying ever­ increasing popularity and presenting new anaesthetic challenges, can be potentially hazardous due to the intraperitoneal insufflation of CO 2 that is required for the procedure. Laparoscopy may lead to possibly harmful cardiovascular and respiratory alterations that could possibly be harmful for the patient. Numerous studies have focused on the effe...

Accuracy of pulse oximetry during neonatal resuscitation

Pulse oximetry during intraaortic balloon pump application.

BACKGROUND Pulse oximeters are multiple used devices in anaesthesiology and intensive care medicine and must provide reliable data during various conditions of signal interference, including light, motion and reduced perfusion. The aim of this study was to evaluate the reliability of different new-generation pulse oximeters during intraaortic balloon pump (IABP) therapy. METHODS In the experi...

Pulse Oximetry

The principal advantage of optical sensors for medical applications is their intrinsic safety since there is no electrical contact between the patient and the equipment. (An added bonus is that they are also less suspect to electromagnetic interference). This has given rise to a variety of optical techniques to monitor physiological parameters: for example, the technique of Laser Doppler veloci...

Pulse Oximetry

Introduction There is no doubt that pulse oximetry represents the greatest advance in patient monitoring in many years. It has the unique advantage of continuously monitoring the saturation of hemoglobin with oxygen, easily and noninvasively, providing a measure of cardio-respiratory function. By virtue of its ability to quickly detect hypoxaemia, it has become the standard of care during anaes...
