BACKGROUND Continuous noninvasive arterial pressure monitoring devices are available for bedside use, but the accuracy and precision of these devices have not been evaluated in a systematic review and meta-analysis. METHODS The authors performed a systematic review and meta-analysis of studies comparing continuous noninvasive arterial pressure monitoring with invasive arterial pressure monito...

BACKGROUND Hemoglobin levels must be obtained through blood draws, which are invasive, time-consuming, and provide only 1 data point at a time rather than continuous measurements. The Masimo Radical-7 SpHb Station (Masimo Corporation, Irvine, CA) has been shown by its manufacturers to provide accurate noninvasive hemoglobin measurements in physiologically normal patients. The objective of this ...

BACKGROUND The clinical and hemodynamic assessment at the bedside and the use of pulmonary artery catheter for the estimation of hemodynamic data have been used in decompensated heart failure. However, there are no data on the use of continuous noninvasive hemodynamic monitoring. OBJECTIVE To compare the data obtained through noninvasive hemodynamic monitoring with invasive ones in patients w...

conclusions: rsbi and apache ii score in patients with copd exacerbation are of the ability to predict niv requirement, as a predicting factor of non-invasive ventilation requirement. results: patients requiring niv included 43.9 % of all studied patients. rsbi and apache ii score with sensitivity of 94.8 %, (cut off point = 110) and 72 % (cut off point = 14) respectively, had high diagnostic s...

BACKGROUND Initial postoperative core temperature is a physician and hospital performance measure. However, the extent to which core temperature changes during emergence from anesthesia and transport from the operating room to the postanesthesia care unit (PACU) remains unknown. Similarly, the accuracy of many noninvasive temperature-monitoring methods used in the PACU has yet to be quantified....

BACKGROUND The main concern in noninvasive (NI) glucose measurement is achieving high accuracy readings, although no blood (or other fluid) is involved in the process. Using methods based on different physical properties of a measured object can ensure the independence of each of the readings and therefore improve the validity of the end result. By using a combination of (three) independent tec...

BACKGROUND AND PURPOSE Internal carotid artery dissection has increasingly been reported as a cause of transient ischemic attack or stroke. However, scarce data exist on the natural history of the arterial lesions and the temporal profile of recanalization. METHODS We followed 48 patients with 50 angiographically confirmed internal carotid artery dissections by sequential duplex Doppler studi...

This article provides a systematic review of the literature on the application of noninvasive ventilation in various forms of hypercapnic and hypoxemic respiratory failures. A description of the underlying pathophysiology is followed by a review of physiologic data explaining the mechanisms of action of noninvasive ventilation. A critical review of clinical studies is presented with specific su...
