Our Mission

At ClearFlow, our mission is to protect the quality of life by helping clinicians improve outcomes and advance healing through sustainable medical technologies.

Making Retained Blood Syndrome (RBS) a never event

Blocked chest tubes happen every day in every hospital, yet they are impossible to predict. This means all your critically ill patients are at risk of complications linked to Retained Blood Syndrome (RBS).

Retained Blood Syndrome (RBS) complications are serious and can result in impaired outcomes, hospital readmissions, increased length of stay, doubled mortality rates and high hospital costs.15 Clinicians do their best to manage clogged chest tubes, but conventional methods such as milking and stripping are ineffective and may even be harmful.3, 13, 18

Now, with PleuraFlow® Active Clearance Technology® (ACT), you can proactively ensure optimal evacuation of blood and fluids during the crucial first hours post surgery. Let’s make Retained Blood Syndrome (RBS) a never event and clear the pathway for all patients towards a successful recovery.

Advocating a new Standard of Care

We are committed to giving clinicians the tools needed to prevent Retained Blood Syndrome (RBS) from blocking patients’ recovery. At ClearFlow, we advocate the establishment of Standards and Guidelines for chest drain patency to be actively maintained in the first 24 hours post surgery. ClearFlow can help you implement a Continuous Quality Improvement (CQI) program at your hospital.
Learn how

Compelling clinical evidence for the introduction of uniform chest drain patency maintenance standards will be submitted to the Society of Thoracic Surgeons (STS) and the American Association for Thoracic Surgery (AATS).

Elevate patient care. Share the data and champion the adoption of these new standards to help free your hospital, your patients and their families from the burdens of Retained Blood Syndrome (RBS).

Top institutions trust PleuraFlow ACT

Increasingly, the most highly respected clinicians in the U.S. are relying on PleuraFlow® ACT to ensure effective chest tube patency. Learn why surgeons who have access to the very best tools available are choosing PleuraFlow Active Clearance Technology (ACT).
