The purpose of this study is to evaluate the variations of respiratory changes in pulse oximeter plethysmographic amplitude (delta POP) according to different contact forces between finger and sensor of pulse oximeter. During general anesthesia without surgical stimuli, pulse oximeter sensor is applied with contact force of 0.2-0.4N and POP waveform is obtained for 90 seconds. Then, pulse oximeter sensor is applied with contact force of 0.8-1.0N and measurement will be repeated. Delta POP will be calculated and compared.

This is a prospective, non-blinded, non-randomized, interventional study of the Masimo pulse oximeter and sensors in a trauma setting.
Pulse oximetry is an important diagnostic tool in monitoring and treating both in-patients and ambulatory patients. Modern pulse oximeters exploit different body sites (eg fingertip, forehead or earlo...
Pulse oximetry, a relatively inexpensive technology, has the potential to improve health outcomes by reducing incorrect diagnoses and supporting appropriate treatment decisions. There is evidence that...
ClearSight is a noninvasive arterial blood pressure monitor, but it remains unknown whether it is affected by the state of perfusion to the fingers. We investigated whether the lower perfusion index (...
Isobornyl acrylate (IBOA) is a potent contact sensitizer contained in the glucose sensor FreeStyle Libre (1). Many cases of allergic contact dermatitis (ACD) have already been described in this regard...
In recent years, measures of cardiac interoceptive accuracy have been heavily scrutinised. The focus has been on potentially confounding physiological and psychological factors; little research has ex...
Extraoral devices for applying force to the dentition in order to avoid some of the problems in anchorage control met with in intermaxillary traction and to apply force in directions not otherwise possible.
The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
