Surfactant Protein Deficiency Disorders

Surfactant Protein Deficiency Disorders (SP-D) encompass a range of conditions where the production or function of surfactant proteins is impaired, leading to respiratory problems. These disorders can affect individuals of any age, from newborns to adults. Understanding the types, causes, symptoms, diagnostic tests, treatments, drugs, surgeries, preventions, and when to seek medical attention is crucial for managing SP-D effectively.

Types of Surfactant Protein Deficiency Disorders:
