Calculated negative pressure developed in the lung plotted against the outside diameter of the suction catheter to the inside diameter of the airway. Calculated negative pressure developed in the lung plotted against the outside diameter of the suction catheter to the inside diameter of the airway. Each curve represents a catheter with a different wall thickness, expressed as the ratio of the catheter's inner diameter to outer diameter. (Data from reference 1.)‏ Christopher J Russian et al.
