EasyVEE® flow driver “jet” 

The Jet device (Venturi unit) works as an high flow driver (booster) for high flow oxygen therapy through the use of HFNC or for CPAP, and it requires the gas supply from an Oxygen source only.
For CPAP application, this device must be used only for the ventilation with the specific mask or with hood. It requires a PEEP valve placed on the outlet of the expiratory side.

The JET system is mainly indicated for:

  • Acute respiratory distress syndrome (ARDS)
  • Severe respiratory distress
  • Post-surgery hypoxemia
  • Asthma
  • Chronic obstructive pulmonary disease (COPD)
  • Thoracic trauma
  • Prophylaxis and treatment of acute apnoea attacks
  • Pulmonary oedema and atelectasis of varying origins, and for weaning from a mechanical ventilator

In hyaline membrane diseases, the alveoli expand with difficulty during inspiration and tend to collapse during expiration. Loss of alveolar tone associated with other causes such as endoalveolar transudation, interstitial oedema, the lack of or deficient surfactants, cause a series of modifications in the respiratory mechanism and distribution of air in the lungs leading to severe and progressive respiratory distress. Alveolar distension can be partially supported with a continuous positive airway pressure (CPAP), between the respiratory tract and the outside, throughout the entire respiratory cycle.

The aim of the pressure gradient is to:

  • Ensure a greater opening of the alveoli during inspiration
  • Prevent alveolar collapse at the end of expiration, by maintaining a PEEP level
  • Reduce the effort necessary to breathe, thus avoiding hypoxemia, hypercapnia, metabolic and respiratory acidosis typical of IRDS

CPAP respiration, applied with any method, requires the patient’s efficient spontaneous respiration (cases with frequent apnoea, or severe respiratory failure, require ventilator support). To the patient is administered a gaseous mixture, with an appropriate concentration of O2, metered in L/min. by one or two oxygen flow meters, and the CPAP is obtained by discharging through a respiratory circuit terminal (PEEP valve), the expired gases.
