Pegaso Vent

Pegaso Vent is a negative pressure ventilator and represents the primary and most traditional method of assisted long-term ventilation.

Pegaso Vent withdraws mechanically the air from a chamber, which embraces the chest (or the whole body) and as a consequence creates a sub-atmospheric pressure inside. This leads to an expansion of the chest, which causes a decrease in intrapulmonary pressure, and increases flow of ambient air into the lungs. When Pegaso Vent switches to positive pressure and forces air in the chamber, the chest will be compressed and the lungs will exhale. The exhalation can also be passive, through ambient instead of positive pressure, which often is sufficient to deflate the lungs.

This ventilation method reproduces mechanically ventilation similar to the human spontaneous breathing.

The following accessories can be connected to Pegaso Vent:

Even though this is a rather traditional ventilation system, today there is still an important role for negative pressure ventilation (NPV).

It is recommended to use NPV when patients have the following problems:

  • intolerance of facial mask (claustrophobia)
  • facial deformity
  • excessive airway secretion
  • respiratory distress syndrome of the newborn (treated with continuous negative pressure ventilation CNEP)
  • respiratory distress syndrome of children due to bronchiolitis
  • chronic respiratory failure in patients with chronic obstructive pulmonary disease and restrictive thoracic disorders

The many advantages of NPV compared to the invasive techniques, especially in the management of ICU settings, can be summarised as follows:

  • normal swallowing, feeding, speech are maintained
  • significant reduction of costs and risks related to invasive endotracheal intubation
  • shorter stays in ICU
  • less sedatives are necessary
  • general cost reduction of ICU management
  • weaning process of ventilated patients becomes easier and more natural

NPV continues to cover an important role for diagnostic and therapeutic surgeries carried out with the fibrebronchoscopy.

For all patients that use NPV at home on a longterm basis the following advantages can be highlighted:

  • greater comfort as an almost “natural” breathing is allowed
  • the possibility to eat, drink, talk and cough, even when mechanically ventilated
