What is Subsegmental atelectasis in the lung?
Terminology. The term subsegmental atelectasis includes any loss of lung volume so small that it does not cause indirect signs of volume loss (as might be seen with larger atelectases).
What causes Subsegmental atelectasis?
Platelike atelectasis Also called discoid or subsegmental atelectasis, this type is seen most commonly on chest radiographs. Platelike atelectasis probably occurs because of obstruction of a small bronchus and is observed in states of hypoventilation, pulmonary embolism, or lower respiratory tract infection.
Is atelectasis life-threatening?
If enough of the lung is affected, your blood may not receive enough oxygen, which can cause health problems. Atelectasis often develops after surgery. It is not typically life-threatening, but in some cases, it needs to be treated quickly.
What are the three types of atelectasis?
The term atelectasis can also be used to describe the collapse of a previously inflated lung, either partially or fully, because of specific respiratory disorders. There are three major types of atelectasis: adhesive, compressive, and obstructive.
Does atelectasis go away?
Treatment. Treatment of atelectasis depends on the cause. Mild atelectasis may go away without treatment. Sometimes, medications are used to loosen and thin mucus. If the condition is due to a blockage, surgery or other treatments may be needed.
What are the signs and symptoms of atelectasis?
There may be no obvious signs or symptoms of atelectasis. If you do have signs and symptoms, they may include: Difficulty breathing (dyspnea) Rapid, shallow breathing.
Is atelectasis curable?
Atelectasis is seldom life-threatening and usually resolves spontaneously. If atelectasis is caused by a mucous plug or inhaled foreign object, it is curable when the plug or object is removed.
