Bronchiectasis – Condition and Treatment

Bronchiectasis (brong-ke-EK-tah-sis) comes from the Greek words “bronckos”
Bronchiectasis - Condition
Bronchiectasis
(airway) and “ektasis” (widening). It is the abnormal widening of the airways in the lungs usually caused by damage to the airway walls. This should never be mistaken for Bronchitis.   Bronchiectasis is a common lung disease characterised by chronic infection in small airways that results in some parts of the lung becoming damaged, scarred and dilated, allowing infected mucus to build up in pockets. This condition is characterised by a persistent cough with excess amounts of mucus and, often, airflow obstruction together with episodes of worsening symptoms.   In healthy individuals, glands in the lining of the airways make small amounts of mucus, which keeps the airways moist and traps inhaled dust, dirt and organisms. Usually, when mucus becomes excessive it is either coughed up and out, or swallowed. However, in people with bronchiectasis, the mucus pools where the airway is widened and makes the person prone to recurrent respiratory tract infections.

Causes of Bronchiectasis

There is conflicting information about the actual causes of Bronchiectasis. But most information point to the fact that Bronchiectasis is rarely the initial condition, usually Bronchiectasis is the result of other lung conditions which then lead to Bronchiectasis further down the line.

  Bronchiectasis is caused due to an excess amount of mucus in the airway, or a degradation of the lung tissue. This causes a breakdown of the walls and the distortion of the airway to create a bulge or a pocket in the wall of the airway which acts to trap mucus and foreign bodies in the lungs. This excess mucus and break down of the walls can be caused by a number of conditions included, but not limited to:

For Bronchiectasis to develop, it requires a condition which does one of the following:

  1. Degrades the lung tissue,
  2. Creates excess mucus or
  3. A combination of both.
 

Cystic Fibrosis is one of the major causes of Bronchiectasis (up to 50% of cases) in children, but because cystic fibrosis is hereditary, it is rarely, if ever, the cause of Bronchiectasis in adults unless the initial damage was started as a child.

Bronchiectasis occurs frequently in association with pulmonary tuberculosis and is caused primarily by tuberculous bronchitis. It is common in all types of tuberculosis, especially in the fibroid lesion stage. It may occur with active tuberculosis and become part of the tuberculous picture. It may also occur with inactive tuberculosis and then present a distinct symptom complex. In the case of adults, although many people who develop bronchiectasis have been smokers, there has never been a direct link between smoking and Bronchiectasis. Although lung conditions like Chronic Obstructive Pulmonary Disease (COPD), including Bronchitis, Asthma and Emphysema in adults may lead to an adverse immune system over reaction which results in Bronchiectasis. Similarly with Bronchiectasis, if not treated, can develop into atelectasis.

How to Manage and Treatment of Bronchiectasis

Management of Bronchiectasis is complex because of the variety of underlying causes. Clinical decisions around the management of the condition are made based on individual presentations.

Treatment for Bronchiectasis may include:

  • Physiotherapy,
  • Use of medicines (particularly to control infections),
  • Regular influenza vaccinations and,
  • Where appropriate, surgery

What happens over the years with Bronchiectasis?

Patients tend to have ongoing symptoms but these can generally be controlled with treatment and the vast majority of patients live active independent lives. A small proportion of patients develop rapidly progressive/severe disease and for these patients more aggressive management and regular review by a respiratory physician are recommended.

How Does AirPhysio Help Treat Bronchiectasis?

By using the AirPhysio device to clean the airway and condition the lungs, this will assist in clearing out the pockets of mucus, as well as a physiotherapy method to assist in the maintenance of Bronchiectasis.

  AirPhysio assists in the treatment of Bronchiectasis in 2 distinct ways: 1. Firstly the combination of the Positive Expiratory Pressure combined with the oscillating effect helps to reduce the elasticity of the mucus, allowing the device to loosen the mucus from the airway walls to assist in the mucus clearance process through the 2 stages of the AirPhysio mobilization and elimination method. 2. Secondly, the vibration AirPhysio including the deep breathing method assist to condition the airway and assists to improve lung capacity through a physiotherapy method of exercising the lungs.
