Abstract:
A ventilation training analyzer manikin, for providing a quantitative measurement of the relative proportions of breathable gas volume delivered to a patient's lungs and patient's stomach during ventilation attempts by a user, the manikin comprising:an anatomical simulation of a human respiratory tract including a pharynx model structure, a larynx model structure; and lung modelling means for mimicking the physiological attributes of a human bronchia and lungs;an anatomical simulation of an upper portion of a human alimentary canal including said pharynx model structure and an esophagus model structure with lower esophageal sphincter modelling means for mimicking the physiological attributes of a human lower esophageal sphincter to open when gas pressure differential between an upstream and a downstream portion of the esophageal model structure exceeds a selected threshold pressure differential; and wherein:the lung modelling means including lung gas volume measuring means for capturing and measuring the tidal volume of gas delivered to the lung modelling means by the user; andthe lower esophageal sphincter modelling means including stomach gas volume measuring means for capturing and measuring the tidal volume of gas delivered to the lower esophageal sphincter modelling means by the user.
