Where <i>P<sub>0.1</sub></i> is the airway occlusion pressure, measured 100 ms after the onset of inspiration during quiet breathing. We set this to a constant healthy value of 0.75. <i>P<sub>min</sub></i> is the largest negative pressure value during inhalation and <i>P<sub>max</sub></i> is the largest positive pressure value during exhalation, the combination of which specifies the amplitude of the pressure source signal. Each time value (<i>t</i> with a subscript) is determined using set fractions and the total breath time to achieve the desired inspiratory-expiratory ratio. Figure 3 shows the basic segmented muscle driver waveform used.
