*Mean = (mean TEBT + mean TTE)/2; **Bias = TEBT – TTE. CPAP, continuous positive airway pressure; HFOV, high frequency oscillatory ventilation; HFJV, high frequency jet ventilation; ACV, assist control ventilation; LOA, limits of agreement; NS, not stated; PE, percentage error; SD, standard deviation; SIMV, synchronized intermittent mandatory ventilation; TEBT, thoracic electrical biosensing technology; TTE, transthoracic echocardiography. Bold values have been calculated from available data or determined from provided from graphs.
