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 (PI) measured with a pulse oximeter, which reflects finger perfusion, would affect the agreement between arterial pressures measured with ClearSight versus those obtained with an arterial catheter.

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...
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...
The ductus arteriosus is a necessary structure in fetal circulation, and its patency can produce hemodynamic alterations. The diagnostic gold standard is echocardiography, not always available. In the...
Recently, a novel index of arterial stiffness was developed to eliminate the placements of transducers on the carotid and femoral arteries and to make the measurement substantially easier. We evaluate...
Calibration of a software module that computes SpO2 based on photoplethysmography (PPG) traces acquired by a reflectance-based pulse oximeter which can be placed on the index finger or the...
This study is aimed to assess the effects of intravenously administered three fluid types on perfusion index and pulse variability index in patients during preoperative period. Patients wi...
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...
Spinal anesthesia for caesarean section is associated with a decrease in systemic vascular resistance and cardiac output and may cause hypotension in a significant portion of the parturien...
The aim of this study is to evaluate the validity of perfusion index to determine the level of anesthesia in comparison with auditory evoked potential in children undergoing tonsillectomy.
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.
Lack of perfusion in the EXTREMITIES resulting from atherosclerosis. It is characterized by INTERMITTENT CLAUDICATION, and an ANKLE BRACHIAL INDEX of 0.9 or less.
Use of a pulse of X-rays or fast electrons to generate free radicals for spectroscopic examination.
The signs of life that may be monitored or measured, namely pulse rate, respiratory rate, body temperature, and blood pressure.
A written agreement for the transfer of patients and their medical records from one health care institution to another.
