Device Use

The Twin Tube sample lines play a central role in the Vyntus CPX system. These tubes connect to the dead volume trap (DVT) adapter, allowing for the continuous collection of gas samples from the test subject's breath during Cardiopulmonary Exercise Testing (CPET) measurements. Integrated within the Twin Tubes is a drying hose, which removes moisture from the gas samples to protect the integrity of the gas sensors. These sensors, housed within the device, analyze oxygen (O2) and carbon dioxide (CO2) levels throughout the patient's inhalation and exhalation during exercise, providing valuable pulmonary (lung) function data.

Reason for Recall

Vyaire Medical, Inc. is recalling the Twin Tube due to the potential of the nozzle separating during patient use. The separated component may fall into the patient’s mouth resulting in a potential choking hazard which may lead to an airway obstruction, requiring medical intervention to prevent further injury or harm.

There have been no reports of injuries or deaths associated with this issue.

Who May be Affected

  • Health care Professionals who use the Twin Tube
  • Patients who have undergone testing or treatment involving the Twin Tube
