Vyaire 3100b Ventilator Features

The Vyaire 3100B is a High Frequency Oscillatory Ventilatory. The Vyaire 3100B is Base on the Same platform as the Vyaire 3100A. The 3100 B added additional features for adult patients. The Vyaire can be used on patients that weigh over 77 lb (35kg). The system is used for patients that suffer from acute respiratory distress. The ventilator provides tools that can protect the lungs from damage while it is continuously expending pressure and volume to inflate the lungs. This helps to prevent the patient from going into respiratory failure.

  • Produces an active exhalation, which is essential at high-frequency respiratory rates to prevent air trapping that may occur with passive exhalation.
  • Offers patented technology and a highly reliable, electromagnetically driven piston that distinguishes it from other high-frequency ventilators.
  • Permits variable I:E ratios, which are desirable for managing ventilation.
