Medical Terms Associated with Lung Disease
A glossary of the medical terms and abbreviations associated with lung diseases
1. Interstitial Lung Diseases (ILD) and Pulmonary Fibrosis
These diseases generally involve inflammation, scarring, or other abnormalities of the lung's supporting tissue.
| Abbreviation | Medical Term |
|---|---|
| ILD | Interstitial Lung Disease |
| IPF | Idiopathic Pulmonary Fibrosis |
| PF | Pulmonary Fibrosis |
| PPF | Progressive Pulmonary Fibrosis |
| CTD-ILD | Connective Tissue Disease-Associated Interstitial Lung Disease |
| SSc-ILD | Systemic Sclerosis-Associated Interstitial Lung Disease |
| RA-ILD | Rheumatoid Arthritis-Associated Interstitial Lung Disease |
| HP | Hypersensitivity Pneumonitis |
| CHP | Chronic Hypersensitivity Pneumonitis |
| NSIP | Nonspecific Interstitial Pneumonia |
| UIP | Usual Interstitial Pneumonia (a pathological or imaging pattern) |
| COP | Cryptogenic Organizing Pneumonia |
| DIP | Desquamative Interstitial Pneumonia |
| RB-ILD | Respiratory Bronchiolitis-Associated Interstitial Lung Disease |
| LIP | Lymphocytic Interstitial Pneumonia |
| AIP | Acute Interstitial Pneumonia |
2. Obstructive Lung Diseases
These conditions interfere with airflow through the bronchial tubes and smaller airways.
| Abbreviation | Medical Term |
|---|---|
| COPD | Chronic Obstructive Pulmonary Disease |
| CB | Chronic Bronchitis |
| ACO | Asthma-COPD Overlap |
| CF | Cystic Fibrosis |
| BE | Bronchiectasis |
| BOS | Bronchiolitis Obliterans Syndrome |
| ABPA | Allergic Bronchopulmonary Aspergillosis |
| AERD | Aspirin-Exacerbated Respiratory Disease |
Additional terms: Emphysema, asthma, and bronchiolitis are also important diagnostic terms, although they are commonly written without abbreviations.
3. Pulmonary Vascular Diseases
These involve blood vessels in the lungs and can seriously affect oxygen circulation.
| Abbreviation | Medical Term |
|---|---|
| PH | Pulmonary Hypertension |
| PAH | Pulmonary Arterial Hypertension |
| CTEPH | Chronic Thromboembolic Pulmonary Hypertension |
| PE | Pulmonary Embolism |
| PVD | Pulmonary Vascular Disease |
| PVOD | Pulmonary Veno-Occlusive Disease |
| PCH | Pulmonary Capillary Hemangiomatosis |
4. Infectious and Inflammatory Lung Diseases
These include respiratory infections and conditions involving significant inflammation of lung tissue.
| Abbreviation | Medical Term |
|---|---|
| CAP | Community-Acquired Pneumonia |
| HAP | Hospital-Acquired Pneumonia |
| VAP | Ventilator-Associated Pneumonia |
| TB | Tuberculosis |
| NTM | Nontuberculous Mycobacterial Lung Disease |
| MAC | Mycobacterium Avium Complex |
| RSV | Respiratory Syncytial Virus |
| ARDS | Acute Respiratory Distress Syndrome |
| ALI | Acute Lung Injury (historical term, now generally incorporated into ARDS classifications) |
| PJP | Pneumocystis Jirovecii Pneumonia |
Additional term: Sarcoidosis is an inflammatory disease that can affect the lungs and other organs.
5. Lung Cancers and Tumors
These terms identify major forms of malignant disease affecting the lungs and surrounding tissues.
| Abbreviation | Medical Term |
|---|---|
| LC | Lung Cancer |
| NSCLC | Non-Small Cell Lung Cancer |
| SCLC | Small Cell Lung Cancer |
| LUAD | Lung Adenocarcinoma |
| LUSC | Lung Squamous Cell Carcinoma |
| MPM | Malignant Pleural Mesothelioma |
| PNEC | Pulmonary Neuroendocrine Carcinoma |
6. Pulmonary Testing and Treatment Terminology
These abbreviations describe tests, measurements, treatments, or complications rather than individual diseases.
| Abbreviation | Medical Term |
|---|---|
| PFT | Pulmonary Function Test |
| FVC | Forced Vital Capacity |
| FEV1 | Forced Expiratory Volume in One Second |
| DLCO | Diffusing Capacity of the Lung for Carbon Monoxide |
| HRCT | High-Resolution Computed Tomography |
| 6MWT | Six-Minute Walk Test |
| SpO2 | Peripheral Oxygen Saturation |
| PaO2 | Partial Pressure of Oxygen in Arterial Blood |
| O2 | Oxygen |
| LTOT | Long-Term Oxygen Therapy |
| PR | Pulmonary Rehabilitation |
| CPAP | Continuous Positive Airway Pressure |
| BiPAP | Bilevel Positive Airway Pressure |
| AE-IPF | Acute Exacerbation of Idiopathic Pulmonary Fibrosis |
| OSA | Obstructive Sleep Apnea |
Educational reference only. Some abbreviations have multiple meanings depending on medical context. Diagnosis and treatment should be discussed with a qualified healthcare professional.
