Heat losses from a breathing system with a heated-water humidifier.
Air was "breathed" in the laboratory through a heated-water humidifier and a breathing tube. Several different humidifiers and tubes were used. The temperature rise of the air on passing through the humidifier and the temperature drop on passing through the tube were measured. Both were dependent on ventilation. Insulating the tube and humidifier together with the insertion of baffles in the la...
متن کاملEfficacy of a heated passover humidifier during noninvasive ventilation: a bench study.
BACKGROUND Noninvasive positive-pressure ventilation (NPPV) delivers air at a high flow, which is associated with airway mucosal drying and impaired airway functioning. OBJECTIVES To examine the effects of mechanical ventilation parameters on relative humidity and absolute humidity during NPPV, and to evaluate the effect of a heated passover humidifier on relative humidity, absolute humidity,...
متن کاملEffect of a heated humidifier during continuous positive airway pressure delivered by a helmet
INTRODUCTION The helmet may be an effective interface for the delivery of noninvasive positive pressure ventilation. The high internal gas volume of the helmet can act as a 'mixing chamber', in which the humidity of the patient's expired alveolar gases increases the humidity of the dry medical gases, thus avoiding the need for active humidification. We evaluated the temperature and humidity of ...
متن کاملMoisturizing and mechanical characteristics of a new counter-flow type heated humidifier.
BACKGROUND During mechanical ventilation effective conditioning of inspired air is important. In this respect, conventional humidifiers do not perform optimally. By design, a counter-flow-type humidifier should improve humidification and heating, but may increase resistance. METHODS We investigated mechanical impedance and work of breathing (using pressure-flow characteristics and additional ...
متن کاملThe DESIGN of Virtual Environments with particular reference to VRML
The sections on designing within current and future versions of VRML were written by Dr Avon Huxor, post-doctoral researcher in virtual environments, who also contributed sections on interaction in social spaces and augmented realities. Helena Athoussaki and Grethe Mitchell, postgraduate students of the MA Design for Interactive Media, built a VRML model as the other component of this SIMA Proj...
