What is a standard of care? Who defines standard of care? And when does new technology, such as continuous in-line blood gas monitoring (CILBGM), become a standard of care? Perhaps the most productive and practical way to view standards of care in perfusion is as, "the best perfusion management we can provide for our patients within reason and affordability." Today, CILBGM offers a tangible pat...

Arterial oxygen saturation (SaO(2)) and partial arterial pressure of carbon dioxide (PaCO(2)) are important respiratory parameters in critically ill neonates. A sensor combining a pulse oximeter with the Stow-Severinghaus electrode, required for the measurement of peripheral oxygen saturation (SpO(2)) and transcutaneous partial pressure of carbon dioxide (PtcCO(2)), respectively, has been recen...

BACKGROUND AND OBJECTIVES Although many features of robotic prostatectomy are similar to those of conventional laparoscopic urological procedures (such as laparoscopic prostatectomy), the procedure is associated with some drawbacks, which include limited intravenous access, relatively long operating time, deep Trendelenburg position, and high intra-abdominal pressure. The primary aim was to des...

background: cardiac output (co) is the total volume of blood pumped by the heart per minute and is a function of heart rate and stroke volume. co is one of the most important parameters for monitoring cardiac function, estimating global oxygen delivery and understanding the causes of high blood pressure. hence, measuring co has always been a matter of interest to researchers and clinicians. sev...

A gas chromatography-mass spectrometry method for determining exposure to the chemical warfare agent 2,2'-dichlorodiethyl sulfide (sulfur mustard; HD) has been developed. The technique is based upon quantitating thiodiglycol (TDG) released from blood protein adducts that are formed upon exposure to HD. Protein was precipitated from plasma, whole blood, or packed red blood cells (RBCs) and then ...

Methods A group of 7 healthy volunteers were instructed to hyperventilate for 1 and 2 minutes followed by a long free breath hold. A second group of 5 aquatic athletes performed a 60s breath hold and a free maximal breath hold. BOLD-sensitive SSFP cines were acquired during breath holds as well as before and after hyperventilation. Changes in signal intensity over the procedures were expressed ...

The problem of factors influencing the sensors in a mine gas monitoring system cannot be solved by a single sensor itself. The multi-sensor information fusion technique was put forward to increase the system’s information utilance, precision, dependability and error tolerance. Based on the information source that the mine gas monitoring system has collected, the system’s structure mode was defi...

Continuous noninvasive monitoring of oxygenation in premature neonates with respiratory distress is essential to avoid the potential complications of hypoxemia and hyperoxia. The accuracy and reliability of pulse oximetry (using an Ohmeda Biox) was evaluated in 15 premature neonates. Pulse oximetry oxygen saturation readings closely approximated arterial oxygen saturation values analyzed by an ...

A highly sensitive, reproducible, and rapid gas chromatographic method for ethanol determination in various biological specimens (human whole blood, serum, urine, and fecal supernatants) was developed. The method involves direct injection of the biological specimen into the gas chromatograph, without any pretreatment. Contamination of the gas chromatographic column with nonvolatile material was...
