Therapy Overview

Advances in Noninvasive Ventilation


Noninvasive positive pressure ventilation (NPPV or NIV) therapy is respiratory support without the use of an endotracheal tube.

Continuous positive airway pressure (CPAP) and bi-level ventilation are examples of noninvasive therapies. NIV is used to support patients suffering from a range of respiratory diseases without the complications associated with endotracheal intubation.


NIV promotes gas exchange in the lungs
It provides a bulk flow of fresh gas to the alveoli on each inspiration. The use of inspiratory and expiratory positive pressure helps to reduce the work of breathing for the patient.

The use of humidification with NIV
Humidification is vital for maintaining the natural balance of heat and moisture in the airways. Without Essential Humidity, the high pressures and flow rates used with NIV can overwhelm the patient’s natural conditioning mechanism. Large volumes of cool, dry gas may cause the patient’s already compromised respiratory system to deteriorate further.

Essential Humidity maximizes tolerance
By heating and humidifying the gas flow to the same level as that which occurs naturally in the nasopharynx (31 °C, 32 mg/L), patient tolerance to the therapy is maximized in three ways:

  • Increased comfort
  • Reduced airway drying
  • Improved secretion clearance


Essential Humidity compensates for the cooling and drying effects of ventilation gases.
