Non-invasive home lung impedance monitoring in early post-acute heart failure discharge: Three case reports

Figure 1 The technique of lung impedance measurements. A: Three electrodes were placed vertically on the front right side of the chest, 4.5 cm from the midline of the sternum with the upper electrode attached precisely under the clavicle; B: Another set of 3 electrodes was placed on the back along the horizontal line crossing the low edge of the right scapula, with the most leftward electrode placed at the crossing point of the horizontal line with the spine; C: The LI measurement result was displayed as a number on the screen.
