Conscious sedation and pulse oximetry: false alarms?
The use of pulse oximetry in dental procedures involving sedation and children has been encouraged strongly. Reports have indicated that hemoglobin desaturations are not uncommon when a variety of drugs (including nitrous oxide) and dosages are used. The present study investigated the nature of desaturations in relation to patient activity as a function of a drug combination, single drug dose-r...
متن کاملForehead pulse oximetry: Headband use helps alleviate false low readings likely related to venous pulsation artifact.
BACKGROUND This study investigated whether a tensioning headband that applies up to 20 mmHg pressure over a forehead pulse oximetry sensor could improve arterial hemoglobin oxygen saturation reading accuracy in presence of venous pooling and pulsations at the forehead site. METHODS Healthy volunteers were studied breathing room air in supine and various levels of negative incline (Trendelenbu...
متن کاملUse of the peripheral nerve stimulator.
The author discusses various procedures for assessing the patient's degree of muscle relaxation utilizing a peripheral nerve stimulator. Based on clinical observation, a preferred method is offered. To obtain the relaxation necessary for certain surgical procedures, the usual technique is to administer a pre-calculated dose of non-depolarizing muscle relaxant. The most common method to calculat...
متن کاملPulse 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...
متن کاملPulse 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...
