ZOE® Provides EARLY Identification of Decompensation, Prior to Symptom Development!
The ZOE® measures thoracic base impedence which is simply a measurement of the time it takes a small frequency electric current to travel from the top to the bottom of the thorax.

The more resistance the current meets, the drier or less fluid that exists. Conversely, the less resistance that the current meets, the wetter or more fluid that exists in the chest.

ZOE® measurement is a quick and easy method for determining whether individuals are experiencing fluid congestion or dehydration. Research indicates that Zo is an early predictor of congestion in heart failure, showing decreases as early as two weeks prior to weight gain and symptoms.
