Pressure vessels are widely used in industrial fields, and some of them are safety-critical components in the system-for example, those which contain flammable or explosive material. Therefore, the pressure of these vessels becomes one of the critical measurements for operational management. In the paper, we introduce a new approach to the design of non-intrusive pressure sensors, based on ultr...

A newborn baby receiving mechanical ventilation was noted to have an extremely variable degree of hypoxia, despite the administration of 100% oxygen. The hypoxia was relieved rapidly when mechanical ventilation was withdrawn.

BACKGROUND The development of lactic acidemia (LA) in septic shock (SS) is associated with an ominous prognosis. We previously showed that the mechanism of LA in SS may relate to impaired hepatic uptake of lactate, but the mechanism was not clear. Uptake of lactate by the liver occurs by a membrane-associated, pH-dependent, antiport system known as the monocarboxylate transporter. In the hepato...

Cerebral venous blood gas tensions were correlated with elevated intracranial pressure in spontaneously breathing dogs lightly anesthetized with nitrous oxide/halothane. Intracranial pressure was elevated by infusion of artificial cerebrospinal fluid into a lateral ventricle. Respiration and blood pressure were monitored. The results of these experiments indicate that cerebral venous carbon dio...

Physiol. 218(4): 1030-1037. 1970. -The activity of single and multiple cardiac vagal efferent (CVE) fibers was recorded in anesthetized dogs under a variety of conditions. During the inspiratory phase of natural respiration the activity of C...

Indian Journal of Critical Care Medicine ¦ Volume 21 ¦ Issue 9 ¦ September 2017 618 Some evidence suggests that lung‐protective mechanical ventilation (MV) with low‐tidal volume ventilation (LTVV) in addition to positive end‐expiratory pressure (PEEP) could prevent PGD‐induced hypoxemia in the recipients of LT. Nevertheless, these suggestions require further validation in prospective clinical s...

The bronchodilator and cardiac effects produced by aerosols of 0.5% isoprenaline and of 0.25, 0.5, and 1% salbutamol administered in 40% oxygen by intermittent positive-pressure ventilation were compared in 24 asthmatic patients. Isoprenaline and salbutamol in concentrations of 0.5% were equipotent in peak bronchodilator effect; salbutamol was superior in total bronchodilator effect and duratio...

Which means that SVV (%) ≈ pulse pressure variation (PPV; %) for FloTracTM. With the present mathematical equation, it can be demonstrated that the SVV calculated by FloTracTM (SVVFT) is not infl uenced by Khi, which means that SVVFT calculation does not include eff ective arterial elastance (Ea). Th e originality of Garcia and colleagues’ fi nding is that they realized that when measuring PPV ...

During the inflation phase of intermittent positive pressure ventilation gas is compressed in the tubes and connections between the valves of the ventilator and the patient. In machines where the valves are an integral part of the mechanism of the ventilator, and are therefore situated at some distance from the patient, the volume of gas compressed in the collecting tubes may be appreciable. Th...
