i can not draw the graph but on x axis pleural pressure in cm h2o and on y axis expiratory flow rate in l/sec and curve is hyperbolic, plateaue at 5 l/sec expiratory flow rate.............
the graph shows an isovolumetric pressure flow curve obtained at 25% of total lung an increase in which of the follwowing increase the plateau value of expiratory flow rate?
a) airway resistence
b)amt of surfactant in the alveolar space
c)ciliary beating frequency
d)expiratory effort
e) lung vol
f)parasympathetic fiber innervating the airway
