Optimizing responses to intravenous furosemide (ivF) in acute pulmonary edema is limited by current insensitive noninvasive means of volume assessment. We conducted a pilot study to assess the feasibility of performing repeated measures of echocardiographic and bioimpedance analysis (BIA) parameters and test their response as noninvasive markers of volume response to ivF. We also aimed to identify the most potentially sensitive markers of this response. ⋯ Maximal change from baseline for each parameter was greater than its respective intraobserver variability. Performing repeated measures of echocardiographic and BIA parameters is feasible in this unstable group of patients. The above panel of parameters could potentially be used to track volume response to ivF and, thus, to optimize treatment in acute pulmonary edema.
