This thesis details research on the thermal and concentration balancing of a humidification dehumidification desalination system. The system operates similarly to the natural rain cycle. Seawater is heated, sprayed into an airstream to increase the air’s humidity, then pure water is condensed out of the same stream in a separate unit. These systems are typically inefficient due to entropy gener...

The study by Massie et al1 has, for the first time, presented scientific proof that the prophylactic application of a humidifier as an accessory in continuous positive airway pressure (CPAP) therapy can improve not only patient compliance and comfort during treatment, but also the results of the treatment. We consider the study to be of particular importance because it shows that we now have to...

In most circumstances, a nasal route for the delivery of pulmonary aerosol medications is rarely considered; however, in specific instances, this route may be quite useful. Consider, for example, the delivery of aerosol treatments during humidified high-flow nasal cannula use in pediatric critical care, or continuous aerosol delivery via cannula for medications with short durations of action. T...

STUDY OBJECTIVES Nasal continuous positive airway pressure (CPAP) is standard therapy for obstructive sleep apnea syndrome. The effective nasal mask pressure may be adversely affected by factors that increase system resistance (eg, long tubing and/or water condensation) and by dynamic variables (breathing frequency [f] and tidal volume [VT]). The present study was conducted in order to assess t...

We have observed an elevation of body temperature during surgical repair of pectus excavatum. To document this phenomenon and attempt to prevent it, we undertook a combination retrospective-prospective study. The retrospective arm included an analysis of the anesthetic records of patients undergoing repair of pectus excavatum during the past 5 years and included 22 boys and 3 girls. Body temper...
