Radial artery tonometry: moderately accurate but unpredictable technique of continuous non-invasive arterial pressure measurement.
Radial artery tonometry provides continuous measurement of non-invasive arterial pressure (CNAP) by a sensor positioned above the radial artery. An inflatable upper arm cuff enables intermittent oscillometric calibration. CNAP was compared with invasive radial artery pressure recordings from the opposite wrist in 22 high-risk surgical patients with an inter-arm oscillometric mean arterial press...
متن کاملMonitoring of hypotension after spinal anesthesia in cesarean section with continuous non-invasive arterial pressure measurement
We compared continuous non-invasive arterial pressure device and intermittent oscillometric arterial pressure measurement in maintaining hemodynamic stability during spinal anaesthesia for cesarean section. One hundred American Society of Anesthesiologists (ASA) I-II parturients undergoing elective cesarean section under spinal anesthesia were included. Based on a random number table, the partu...
متن کاملInvestigation of the agreement of a continuous non-invasive arterial pressure device in comparison with invasive radial artery measurement.
BACKGROUND Arterial pressure (AP) monitoring should be accurate, easy to use, free of risks, and ideally continuous. The continuous non-invasive arterial pressure (CNAP) device is non-invasive and provides continuous pressure readings. This study was performed to compare the agreement of CNAP and invasive AP monitoring. METHODS Ninety patients undergoing surgery under general anaesthesia were...
متن کاملNon-invasive measurement of the superficial cortical oxygen partial pressure.
We present a non invasive fluorescein based method to measure and visualise the partial oxygen pressure of the rat cortex in a 2D picture. We studied 10 Wistar rats. A trepanation was done over the hemisphere and the dura was opened. A PMMA cylinder with a calibrated optical membrane was fixed over the surface of the brain. The CCD camera with the light source is placed over the cylinder. This ...
متن کاملNon-invasive continuous core temperature measurement by zero heat flux.
Reliable continuous core temperature measurement is of major importance for monitoring patients. The zero heat flux method (ZHF) can potentially fulfil the requirements of non-invasiveness, reliability and short delay time that current measurement methods lack. The purpose of this study was to determine the performance of a new ZHF device on the forehead regarding these issues. Seven healthy su...
