To assess the validity of accelerometry in measuring daily physical activity, the energy consumption calculated by accelerometry, with respiratory gas analysis as a reference, was evaluated in 45 non-athletes during various exercise tests. Subjects were required to (1) walk on a treadmill ergometer at various speeds, (2) walk on a treadmill ergometer at a fixed speed and with a stride of 20% mo...

The current report describes two patients with severe heart failure due to dilated cardiomyopathy in whom discrepancy between thermodilution cardiac output and clinical status was due to left-to-right shunt. Misdiagnosis of shunting was harmful in the early management of the first case. Secundum type atrial septal defect was confirmed by pathology in both cases. Blood samples for oxymetry shoul...

BACKGROUND The Mindray 9006 is a newly developed pulse oximeter. The performance of noninvasive monitoring of arterial oxygen saturation by pulse oximetry (SpO(2)) and pulse rate (PR) with the Mindray 9006 was evaluated. MATERIAL/METHODS Twenty healthy volunteers participated in this study. The Mindray 9006 was evaluated according to guidelines including HS3-A, EP5-A, and EP9-A2 published by ...

BACKGROUND Biological rhythmicity, particularly circadian rhythmicity, is considered to be a key mechanism in the maintenance of physiological function. Very little is known, however, about biological rhythmicity pattern in preterm and term neonates in neonatal intensive care units (NICU). In this study, we investigated whether term and preterm neonates admitted to NICU exhibit biological rhyth...

Ecological studies show that mice can be found at high altitude (HA - up to 4000 m) while rats are absent at these altitudes, and there are no data to explain this discrepancy. We used adult laboratory rats and mice that have been raised for more than 30 generations in La Paz, Bolivia (3600 m), and compared their hematocrit levels, right ventricular hypertrophy (index of pulmonary hypertension)...

Mortality in patients with community-acquired pneumonia (CAP) who require intubation or support with inotropes in an intensive care unit setting remains extremely high (up to 50%). Systematic use of objective severity-of-illness criteria, such as the Pneumonia Severity Index (PSI), British Thoracic Society CURB-65 (an acronym meaning Confusion, Urea, Respiratory rate, Blood pressure, age >/=65 ...

This work presents a model for patient monitoring in Intensive Care Units (ICU), using a WWW application tool Micro WEB-Server (MWS) – an embedded computer system, in order to monitor physiological data, obtained by standard monitors, captured, made available via WEB and temporarily stored (previous 24 hours data). Monitors are connected to, also standard sensors connected to the patient. For t...
