Figure Lengend Snippet: Thoracic pressure (Pth) input schematic. QRS-complexes are detected in the electrocardiogram (ECG, mV) trace (A). Amplitudes of consecutive QRS-complexes are interpolated using a piecewise cubic Hermite interpolating polynomial. This signal is filtered to produce the respiration signal (B), which is in turn scaled linearly given in Eq. 5. The intrathoracic pressure (ITP, mmHg) trace (C) is combined with the scaled respiration curve and filtered using the “movmean” command in MATLAB 2018a to produce Pth (D).
