Fig. 2.

Flowchart derived from process observation. The processes seen by the patient and family are toward the left side, while the clinic and echo laboratory processes (behind the scene steps) are in the middle and right side of the figure. The red stop signs indicate the various steps where delays could occur. EWT is shown as the time taken from activation of the order to acquisition of the first image. The figure demonstrates the redundant steps such as the walking back and forth of the sonographer and CA. RN, registered nurse.
