Providing extracorporeal lung support doesn’t have to be complicated. In fact, we’ve made it incredibly simple. Through innovative designs and advanced technology, the Hemolung Respiratory Assist System provides partial respiratory support using techniques similar to renal dialysis.

What is Respiratory Dialysis®?

Respiratory Dialysis is a simple, minimally invasive approach to extracorporeal carbon dioxide removal (ECCO₂R) for patients with acute hypercapnic respiratory failure. The Hemolung RAS provides Respiratory Dialysis using a simple extracorporeal circuit, low blood flow rates, and a small veno-venous catheter.

What are the applications for Respiratory Dialysis®?

Stage Therapy Goal Effect of Hemolung CO2 Removal Example Diseases
Pre-ventilator Prevent intubation and avoid invasive mechanical ventilation Reduces work of breathing, corrects acidosis and gives patient time to recover from acute decompensation Acute exacerbation of COPD
Acute on ventilator Enable lung protective ventilation Permits de-escalation of ventilator settings while simultaneously correcting acidosis Acute Respiratory Distress Syndrome (ARDS)

How is Respiratory Dialysis® different from other forms of ECCO₂R?

Respiratory Dialysis is the simplest and easiest form of ECCO₂R to implement. The Hemolung RAS utilizes only a single 15.5. Fr veno-venous catheter for vascular access. No arterial puncture is required. The blood flow rate through the circuit is only 350–550 ml/min. The innovative “active mixing” design of the Hemolung RAS allows for clinically significant CO₂ removal at low blood flow rates continuously for up to 7 days with no circuit replacement.

How is Respiratory Dialysis® different from ECMO?

Traditional ECMO systems can provide full pulmonary or cardiopulmonary support depending on their implementation (veno-venous or veno-arterial) and as a result are very invasive, requiring large cannulae and high blood flow rates. Respiratory Dialysis is specifically designed to provide partial extracorporeal support in a less invasive way than other devices, permitting its use in a wider range of patients (including pre-intubation).
