Chronic respiratory failure

A failure of gaseous exchange

Chronic respiratory failure (CRF) is the permanent inability of the respiratory system to oxygenate the blood and/or remove carbon dioxide properly.
It may be the result of a lack of airflow, and therefore the circulation of air through the lungs,or malfunctions in the pulmonary tissues resulting in a reduction of gaseous exchange between air and blood.

Chronic respiratory failure

CRF is sometimes complicated by severe aggravation of respiratory symptoms, resulting in impaired quality of life and loss of independence. Such episodes are serious and can be life threatening.

Chronic respiratory failure impairs daily life as a result of:

  • Shortness of breath
  • Acute fatigue
  • Accelerated heart rate
  • Blue-tinged lips or fingertips (cyanosis) in the most severe cases
  • Sweating or headaches as a result of elevated levels of carbon dioxide in the blood

Home Mechanical Ventilation

Mechanical Ventilation has been widely applied over the past 30 years due to technology advancements and protocol upgrades to treat CRF; hence it has led to an emergence of Home Mechanical Ventilation (HMV).

What is Home Mechanical Ventilation?

Home Mechanical Ventilation (HMV) is defined as an intermittent or continuous use of an HMV device through a mask interface (non-invasive) or a tracheostomy tube (invasive) at home. The Non-Invasive Ventilation (NIV) is the most commonly used nowadays after the introduction of effective compensation for air leaks.
