Certainly! Here are the different types of atelectasis:

Types of Atelectasis:

1. Obstructive (Resorptive) Atelectasis:

   • Caused by blockage of the airway leading to collapse of alveoli distal to the obstruction.
   • Commonly results from mucus plugs, tumors, or foreign bodies.

2. Non-obstructive Atelectasis:

   • Includes types not directly caused by airway obstruction:
   • Compression Atelectasis:
     • Results from external pressure on the lung (e.g., pleural effusion, pneumothorax, tumors).
   • Adhesive Atelectasis:
     • Occurs without obstruction due to inadequate surfactant, leading to alveolar collapse.
   • Cicatricial Atelectasis:
     • Results from scarring of lung tissue, often due to diseases like pulmonary fibrosis.
   • Relaxation Atelectasis:
     • Associated with conditions that lead to loss of lung volume in the context of lung diseases.

3. Lobar Atelectasis:

   • Refers specifically to the collapse of one or more lobes of the lung.

4. Segmental Atelectasis:

   • Involves the collapse of a specific segment within a lobe of the lung.
