BACKGROUND To determine the effects of noninvasive mechanical ventilation (NIV) compared with invasive mechanical ventilation (IMV) as the initial mechanical ventilation on clinical outcomes when used for treatment of acute respiratory failure (ARF) in immunocompromised patients. METHODS We searched PubMed, EMBASE, the Cochrane Central Register of(More)
The timetabling problem consists of a set of subjects to be scheduled in different timeslots, a set of rooms in which the subjects can take place, a set of students who attend the subjects, and a set of subjects satisfied by rooms and required by timeslots. The heart of the problem is the constraints that exist as regulations within each resource and(More)
BACKGROUND The number of immunocompromised patients has increased in recent years. Acute respiratory failure is a common complication leading to intensive care unit (ICU) admission and high mortality among such patients. The use of non-invasive ventilation (NIV) or oxygen therapy among these patients remains controversial, according to the inconsistent(More)
The paper designs and establishes a set of membrane oxygen-enriched air supply system. Experimental research is conducted for LTV-PS roll-type oxygen-enriched membrane module, results of which show that oxygen-enriched concentration is on the rise with the increase of pressure and air flow. Under normal operating temperature, the concentration of O2 in(More)
It is introduced a solar desalination process using air humidification and dehumidification. In order to increase the output of freshwater, multi-technologies are adopted, the double-pass solar air heater and tubular solar collector are used to heat the air and seawater respectively. The air is humidified by bubbling in the seawater pool, and dehumidified(More)
