Bibasilar Atelectasis

Bibasilar atelectasis is the partial or total collapse of the lungs, caused by the deflation of alveoli. Alveoli are the small air sacks in the lungs that aid with the absorption of oxygen into the bloodstream. Thus, any impairment in their function will result in a reduced intake of oxygen and associated lack of energy.

Description and Symptoms

Bibasilar atelectasis largely affects the left and right sides of the lower lungs, though in some cases it may describe the complete collapse of the lung.

The main risk with atelectasis is difficulty breathing though there are a couple of other symptoms to be aware of, including rapid, shallow breathing and coughing. As a common complication of other conditions, it’s most likely to occur when you’re already in hospital. You should always seek emergency attention if you are experiencing any difficulty breathing.

Atelectasis can also lead to scarring called ‘bibasilar scarring’. In extreme cases, the condition can lead to complete respiratory failure, low blood oxygen (hypoxemia) or pneumonia.

Causes

Often bibasilar atelectasis will be a complication of another condition affecting the lungs, such as lung tumors, inhaled foreign objects, chest injuries, respiratory weakness or others.

Generally, the causes of atelectasis can be split into two categories: obstructive or nonobstructive. In the former case, the damage is caused by a blocked airway. In the latter, it is normally due to pressure or impact from outside. Common causes of obstructive atelectasis are mucus plugs, foreign bodies or blood clots.

Treatment

Treatment will depend on the severity of the condition. If only a small area has been affected, then no treatment may be necessary. In cases where an outside obstruction is the cause, then removing or shrinking that blockage will be a priority. Foradil is a medication that can help to expand the bronchial tubes, while Acetadote can be used to thin the mucus to help the body drain it.

    I have recently been diagnosed with bibasilar atelectasis and have been having daily panic attacks. They are terrifying. I have had stress in my life but nothing compares to this and never had a panic before. Can the atelectasis cause this and what is treatment. This is terrible and I read elderly people like me have a 75% greater risk of dying in 5 years with just One attack. Please help. Can you email me please as this is terrifying?
