Clinical Study on the Noninvasive Lung Fluid Monitoring System in Guiding the Treatment of Heart Failure

"ReDS™ measurements will be shared with the treating clinicians to guide diuretic treatment when discharge, home visit and outpatient follow-up, but blinded to the subjects.~At discharge:① If the ReDS™ reading \<36%, discharge as planned; ②ReDS™ reading ≥36%, increase the oral diuretic dose, discharge as planned.~When home visit and outpatient follow-up: ① If the ReDS™ reading \<20%, hold diuretics; ② If the ReDS™ reading was between 21-35%, maintain current diuretic dose and optimize GDMT. If the ReDS™ change ≥ 6% from the previous one, increase diuretic dose and optimize the GDMT; ③ If the ReDS™ reading was between 36-45%, increase diuretics and optimize the GDMT, then repeat ReDS™ test after 1 week(home visit); ④ If the ReDS™ reading was above 46%, consider intravenous diuretic therapy, and repeat ReDS™ test after 1 week(home visit) or hospitalization."

ReDS measurements will not be shared with the treating clinicians and the subjects, diuretic treatment will only be guided using standard clinical care.
