## Abstract ## Background Pulse wave transit time is a novel method of estimating continuous cardiac output (esCCO). Since there are not many studies evaluating esCCO, we compared it with arterial pressure based cardiac output (APCO) method (FloTrac). ## Methods In this prospective single-center observational study, we included 50 adult patients planned to undergo supramajor oncosurgeries, where major blood loss and extensive fluid shifts were expected. Cardiac output (CO) measurements were obtained by both methods at five distinct time points, giving us 250 paired readings of stroke volume index (SVI) and cardiac index (CI). We analyzed these readings using Pearson's correlation coefficient and Bland–Altman plots, along with other appropriate statistical tests. ## Results There was significant correlation between CI and SVI measured by the esCCO and APCO. Bland–Altman plot analysis for CI showed a bias of −0.44 L/minute/m^2^, precision of 0.74, and the limits of agreement of −1.89 and +1.01, while the percentage error was 46.29%. Bland–Altman analysis for SVI showed a bias −5.07 mL with a precision of 9.36, and the limits of agreement to be −23.4 to +13.28. The percentage error wa
