“…Transesophageal echocardiography, a well-established clinical tool for circulatory evaluation, is a feasible, rapid, safe, and semi-invasive monitoring device suitable for use in patients undergoing surgery under general anesthesia and mechanical ventilation, regardless of the position [26]. Dessap et al [27] reported that the feasibility, tolerance, and image quality of the standard views of TEE were good in the prone and supine positions.…”

BACKGROUND: Cardiac output (CO) decreases on reversing the patient’s position to the prone position. Estimated continuous cardiac output (esCCO) systems can noninvasively and continuously monitor CO calibrated by patient information or transesophageal echocardiogram (TEE). OBJECTIVE: To compare the accuracy, precision, and trending ability of two calibration methods of CO estimation in patients in prone position. METHODS: The CO estimates calibrated by TEE (esT) and patient information (esP) of 26 participants were included. CO was collected at four time points. The accuracy and precision of agreement were evaluated using the Bland-Altman method. A four-quadrant plot was used for trending ability analysis. RESULTS: The bias between esP and TEE and between esT and TEE was 0.2594 L/min (95% limits of agreement (LoA): -1.8374 L/min to 2.3562 L/min) and 0.0337 L/min (95% LoA: -0.7381 L/min to 0.8055 L/min), respectively. A strong correlation was found between ΔesP and ΔTEE (p< 0.001, CCC = 0.700) and between ΔesT and ΔTEE (p< 0.001, CCC = 0.794). The concordance rates between ΔesP and ΔTEE and between ΔesT and ΔTEE were 91.9% and 97.1%, respectively. CONCLUSION: Despite limited accuracy and precision, esP showed acceptable trending ability. The trending ability of esCCO calibrated by the reference TEE value was comparable with that of TEE.
