Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Accuracy and precision are measured using Bland Altman analysis by comparing results from the clinical gold standard pulmonary artery catheter to the results from the new device, the bioimpedance cardiac output monitor at 6 time points, after induction and prior to incision, prior to cannulation of the aorta, ten minutes after protamine administration, 30 minutes after arrival in the ICU, one hour after extubation, and one day post-operatively. 2. Polar plot methodology was used to objectify trending ability of the new technique ( AesculonTM). | — |
Secondary
| Measure | Time frame |
|---|---|
| Our secondary aim was to assess whether the surgical incision, and therefore the interruption of the continuity of the skin of the thoracic cavity and opening of the cavity itself, could be an important factor in the reported discrepancy between the two instruments. | — |
