Heart. a The fluid level within the heart is represented as green, yellow, or red depending on the I&O balance unless there is an invasive measure of fluid status, such as, SPV or CVP. In Fig. 7a note the heart has an ICD (implantable cardiac defibrillator) represented by the small icon attached to the upper left side of the heart. b If there is no invasive assessment of cardiac filling and the estimated blood loss is ≥ 20% or the estimated blood volume the inside of the heart will not have a fluid level, but a text alert stating “Need Data.” A text alert in the upper right side of the display, stating “Consider Objective Measure of Fluid Status, e.g. SPV, CVP.”. c If the I&O balance is positive (≥ 60% of the EBV) but this coincides with an objective filling measures of SPV, PPV, CVP, or PAD all showing the heart has a very low filling volume and the most recent hematocrit is over 30 min old, a text alert will be triggered stating “Potential Unrecognized Blood Loss – Consider Measuring Hct”
