Automated Line Clearing
First and only automated clog clearance system clears proprietary 20 Fr. chest tube every 5 minutes, with no human manipulation needed
Digital Fluid Measurement
Digitally measures and displays hourly drainage volume and trends to provide objective data for patient monitoring
Actively monitors system and alerts care team in the event of abnormal event, such as excess/rapid drainage, line kinks/ disconnection, or other system disruption
Displays data on simple and intuitive touchscreen
Small Bore Chest Tubes
Incorporates soft and flexible small-bore chest tubes for patient comfort
Current Drainage Practice is
of cardiac surgery patients experience clogged chest tubes, increasing the risk of blood build-up
of patients are affected by complications from fluid build-up in the chest cavity
Complications from fluid build-up in chest cavity lead to:*
higher in-hospital mortality rate
day increase in hospital length of stay
higher postoperative transfusion rate
*In patients with retained blood versus those without, based on retrospective analysis of outcomes of 6,909 cardiac surgery patients using conventional chest drains
Society Guidelines Strongly Recommend Maintenance of Chest Tube Patency in Cardiac Surgery
The Enhanced Recovery After Surgery (ERAS) society is a multidisciplinary group committed to developing evidence-based initiatives and perioperative guidelines in order to reduce complications and speed patient recovery following surgery. Recent evidence-based guidelines for enhanced recovery after cardiac surgery were published in the Journal of the American Medical Association (JAMA) Surgery.
The guidelines offer multimodal recommendations across the entire perioperative period, with the maintenance of chest tube patency given the society’s strongest recommendation. Furthermore, they advised against chest tube stripping and breaking the sterile field of chest tubes to remove clots, methods that are frequently used in current practice.
