AbstractWe evaluated levels of bacterial colonization in the humidifying cascade reservoirs of 466 mechanical ventilators; 326 reservoirs were cultured after 24 hours and 140 were cultured after 48 hours of continuous mechanical ventilation. Bacterial colonization was absent in 284 (87.1%) of the humidifier reservoirs sampled at 24 hours and 125 (89.3%) of the reservoirs cultured at 48 hours. Levels of bacterial colonization in the remaining humidifiers were low (<100 organisms/mL). The median temperature recorded in the reservoir fluid of 30 different ventilators was 50°C (range 40° to 60°

The Vitalograph bag resuscitator with the old and new reservoirs, the PMR 1, the PMR 2, and the Laerdal bag resuscitator were studied at various oxygen flowrates and ventilation patterns, with and without oxygen reservoirs, to determine fractional delivered oxygen (FDO2) and function of patient valves. The Vitalograph with the new or the old reservoir and the PMR 1 cannot deliver high oxygen concentrations (FDO2> 0.90) and should not be used when high FDO2is important. The PMR 2 and the Laerdal cannot deliver high oxygen concentrations without a reservoir attached; but with a reservoir

Underground pumped storage hydropower (UPSH) plants may be an alternative to store subsurface energy with lower environmental impacts than conventional pumped storage hydropower (PSH) plants.

The amount of storable energy depends on the water mass and the net head between upper and lower reservoirs.

Results of thermal calculation and air distribution among mining workings of an oil mine for the ventilation of an inclined block (mining area) in accordance with a new proposed method have been provided. The method implies that the open space of the drilling gallery of the inclined block upon well drilling and steam pipeline connection is divided by a longitudinal airtight heat-insulating partition. Thus, the fresh air supplied to the incline is divided into two flows: one flow moves between the heated wall and the heat-insulating partition and then is withdrawn through the ventilation well t

Limited validation research exists for applications of breath-by-breath systems of expired gas analysis indirect calorimetry (EGAIC) during exercise. We developed improved hardware and software for breath-by-breath indirect calorimetry (NEW) and validated this system as well as a commercial system (COM) against 2 methods: (i) mechanical ventilation with known calibration gas, and (ii) human subjects testing for 5 min each at rest and cycle ergometer exercise at 100 and 175 W. Mechanical calibration consisted of medical grade and certified calibration gas ((4.95% CO2, 12.01% O2, balance N2), ro

Background The authors report on the appearance of misleading square wave "phantom" capnograph tracings for approximately 3 min after disconnection from the Siemens Servo 900c ventilator. A series of experiments are described to examine the mechanism of this phenomenon. Methods Patients were ventilated using the Siemens Servo 900c ventilator with the following settings: minute volume, 5 1/min; respiratory rate, 8 breaths/min; PEEP, 0 cm H2O; trigger sensitivity, 20 cm H2O. The ventilator was connected to the Siemens Servo Evac 180 evacuation system (25 1/min on evacuation flowmeter). Airway pr

Abstract:
Introduction: Bag-mask ventilation does not always guarantee 100% seal around airway opening and hence delivered fraction of oxygen (FDO2) may vary. Aim: To determine the FDO2 via a standard neonatal selfinflating bag with and without application of leak, without a reservoir bag with flow rates of 0.1, 0.2, 0.4, 0.6, 0.8, 1, 2, 4 and 6 L/min. Method: A test lung with a three way rotator to produce 0%, 30%, 50% and 75% leak was connected to a 3.5 mm ID endotracheal tube (ETT) connected to a VBM standard preterm self-inflating bag of 250 mL without a reservoir. The ETT was connected to ENVENTEC

Dengue Hemorrhagic Fever (DHF) is caused by the dengue virus transmitted by the Aedes aegypti mosquito or Aedes albopictus. The characteristics of the infectious vector determine the spread and timing of the occurrence of infection. The habitat of aedes mosquitoes is generally in regions with tropical climates, high rainfall, and hot and humid temperatures. The design of this study is quantitative with a cross sectional approach. The sample in this study uses a total sampling technique of 45 samples.

Abstract:
The intermittent nature of most renewable energy sources requires their coupling with an energy storage system, with pumped storage hydropower (PSH) being one popular option. However, PSH cannot always be constructed due to topographic, environmental, and societal constraints, among others. Underground pumped storage hydropower (UPSH) has recently gained popularity as a viable alternative and may utilize abandoned mines for the construction of the lower reservoir in the underground. Such underground mines may have complex geometries and the injection/pumping of large volumes of water with high

Abstract:
Reversal of shunting across the ductus arteriosus from right-to-left to left-to-right is a characteristic feature of the birth transition. Given that immediate cord clamping (ICC) followed by an asphyxial cord clamp-to-ventilation (CC-V) interval may augment left ventricular (LV) output and central blood flows after birth, we tested the hypothesis that an asphyxial CC-V interval accelerates the onset of postnatal left-to-right ductal shunting. High-fidelity central blood flow signals were obtained in anesthetized preterm lambs (gestation 128 ± 2 days) after ICC followed by a nonasphyxial (∼40

Abstract. Changes in the geometry of ocean meridional overturning circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the accurate timing and global correlation of short-term glacial-to-deglacial changes of MOC in different ocean basins still present a major challenge. The fine structure of jumps and plateaus in atmospheric and planktic radiocarbon (14C) concentration reflects changes in atmospheric 14C production, ocean–atmosphere 14C exchange, and ocean mixing.

The ages were obtained by 14C plateau tuning, a robust technique to derive both an absolute chronology for marine sediment records and a high-resolution record of changing reservoir/ventilation ages (Δ14C values) for surface and deep waters by comparing the suite of planktic 14C plateaus of a sediment record with that of the atmospheric 14C record.
