Figure 3From: Determination of respiratory gas flow by electrical impedance tomography in an animal model of mechanical ventilation Linear regression analysis and correlation of gas flow measured by EIT and spirometry. Dotted line: y = x + 0, black line: linear regression. a (left, top). Peak inspiratory flow (PIF). b (left, bottom). Late inspiratory flow (LIF). c (right, top). Peak expiratory flow (PEF). d (right, bottom). Late expiratory flow (LEF).Back to article page
