Managing Heart Failure

If you or someone in your life has heart failure, you know how challenging it can be to manage. After a single HF hospitalization, nearly 25% of patients are readmitted within 30 days, and nearly 50% are readmitted within six months.1 The key to reducing readmissions is detecting fluid buildup as early as possible, but current methods for monitoring heart failure are limited.

A weight scale can tell you if your weight is up or down, but it can’t differentiate between weight gain caused by extracellular fluid accumulation due to heart failure or variations in muscle or fat. Although there are other monitoring methods, they are invasive and expensive.

accurate monitoring tool

The SOZO® device offers your healthcare team a noninvasive, accurate, fast and low-cost way to monitor your heart failure symptoms. By detecting small amounts of fluid buildup—as little as 100 ml—SOZO can help your doctors better manage your condition.

Heart failure is the most common cause of hospitalization for people 65 and older.1


Approximately 25% of heart failure patient are readmitted to the hospital within 30 days.1


If fluid buildup is detected early, up to 12 days before readmission, readmissions can be reduced.1-3
