Mechanics of breathing, gas distribution and functional residual capacity at different frequencies of respiration during spontaneous and artificial ventilation.
Nine healthy volunteers were investigated, both while awake and breathing spontaneously, and while anaesthetized with IPPV, in all cases at rates of both 12 and 24 b.p.m. Gas flow and volume were measured with a pneumotachography. The transpulmonary pressure (the pressure difference between the trachea or the buccal cavity and the oesophagus) was also recorded. The distribution of gas was analy...
متن کاملContinuous positive airway pressure effect on functional residual capacity, vital capacity and its subdivisions.
Thirty-four otherwise healthy patients having to undergo elective upper abdominal surgery were randomly assigned to two equal groups. In the treatment group, constant positive airway pressure (CPAP) with an expiratory pressure of 12 cm H2O was applied at one hour following extubation, and at daily intervals for the first five days following surgery for a continuous period of three hours. The co...
متن کاملVentilation/perfusion mismatch caused by positive pressure ventilatory support.
In a patient with lobar atelectasis who was on positive pressure ventilatory support, ventilation and perfusion images showed absent ventilation and normal perfusion (reverse mismatch) in the region of the atelectasis and normal ventilation and decreased perfusion (true mismatch) not caused by pulmonary embolism in another lung zone. We report this case to emphasize that the lung scan findings ...
متن کاملHydrostatic weighing at residual volume and functional residual capacity.
Hydrostatic weighing (HW) was performed at both residual volume (RV) and functional residual capacity (FRC) to determine if underwater weighing at different lung volumes affected the measurement of body density. Subjects were 43 males, 18-25 yr. Subjects were submerged in the prone position, and the lung volume was measured by helium dilution at the time of the underwater weighing. Underwater w...
متن کاملFunctional residual capacity during anaesthesia. I: Methodology.
The helium dilution technique for the measurement of functional residual capacity (FRC) is reviewed with special reference to anaesthesia. A modification is described which permits measurements to be made during intermittent positive pressure ventilation. This modification causes minimal interference with the circuit as it is used for spontaneous respiration. The measuring circuit may be altern...
