Nuwellis Introduces New 24-Hour Aquadex™ Circuit to Support Hospital-Based Outpatient and Short-Term Fluid Management

MINNEAPOLIS, Sept. 04, 2025 (GLOBE NEWSWIRE) -- Nuwellis, Inc., a fluid management company, announced plans to introduce a new 24-hour circuit for Aquadex therapy in the United States this fall. The new circuit is designed for single-day outpatient sessions and complements the company’s existing 72-hour option that is commonly used for multi-day therapy or inpatient care. Together, these options help hospitals match supply to setting while maintaining a consistent therapy experience.

Hospitals are building outpatient Aquadex programs to deliver predictable, scheduled care for patients who need fluid removal without a hospital admission. The 24-hour circuit supports that model by aligning with single-visit workflows, easing scheduling, and program planning. For patients, the goal is a straightforward same-day visit. For providers and administrators, the aim is a reliable pathway to run more efficient clinics and scale capacity.

“Hospital-based outpatient Aquadex therapy is growing as a reliable option for patients who need fluid removal without a hospital admission. The 24-hour circuit supports that model with a straightforward single-visit pathway,” said John Erb, Chairman of the Board and Chief Executive Officer of Nuwellis. “This addition is about meeting sites where they are, helping teams expand access to Aquadex therapy in a clinic setting and supporting consistent, high-quality care across both outpatient and inpatient programs.”

Nuwellis provides program resources for hospital-based outpatient sites, including patient identification, implementation guidance, and staff education to help teams add or expand Aquadex therapy in ambulatory settings.
