In
medicine, 'pulmonology' (aka 'pneumology') is the specialty that deals with
diseases of the
lungs and the
respiratory tract. It is called 'chest medicine' and 'respiratory medicine' in some countries and areas. ''Pulmonology'' is generally considered a branch of
internal medicine, although it is closely related to
intensive care medicine when dealing with patients requiring
mechanical ventilation.
Surgery of the respiratory tract is generally performed by specialists in
cardiothoracic surgery (or
thoracic surgery). 'Chest medicine' is not a specialty in itself but is an inclusive term which pertains to the treatment of diseases of the chest and contains the fields of pulmonology, thoracic surgery, and
intensive care medicine. Pulmonology is concerned with the diagnosis and treatment of
lung diseases, as well as secondary prevention (
tuberculosis). Physicians specializing in this area are called pulmonologists.
Diagnosis
In
medicine, 50% of all diagnoses can be made by a thorough medical history, and lung diseases are no different. The pulmonologist will conduct a general review and focus on:
★ hereditary diseases affecting the lungs (
cystic fibrosis,
alpha 1-antitrypsin deficiency)
★ exposure to
toxins (
tobacco smoke,
asbestos,
exhaust fumes,
coal mining fumes)
★ exposure to
infectious agents (certain types of
birds, malt processing)
★ an
autoimmune diathesis that might predispose to certain conditions (
pulmonary fibrosis,
pulmonary hypertension)
Physical diagnostics are as important as in the other fields of
medicine.
★ Inspection of the hands for signs of
cyanosis or
clubbing, chest wall, and respiratory rate.
★ Palpation of the
cervical lymph nodes,
trachea and chest wall movement.
★ Percussion of the lung fields for dullness or
hyperresonance.
★
Auscultation (with a
stethoscope) of the lung fields for diminished or unusual
breath sounds.
As many
heart diseases can give pulmonary signs, a thorough cardiac investigation is usually included.
Other tools include:
★
Laboratory investigation of
blood (
blood tests). Sometimes
arterial blood gas measurements are also required.
★
Spirometry (the determination of
lung volumes in time by breathing into a dedicated machine; response to
bronchodilatators and
diffusion of
carbon monoxide)
★
Bronchoscopy with
bronchoalveolar lavage (BAL),
biopsy and
epithelial brushing
★
Chest X-rays
★
CT scanning (
MRI scanning is rarely used)
★
Scintigraphy and other methods of
nuclear medicine
★
Positron emission tomography (especially in
lung cancer)
Treatment
Surgical treatment in generally performed by the (
cardio)
thoracic surgeon, generally after primary evaluation by a pulmonologist.
Medication is the most important treatment of most diseases of pulmonology, either by inhalation (
bronchodilators and
steroids) or in oral form (
antibiotics,
leukotriene antagonists).
Oxygen therapy is often necessary in severe respiratory disease (
emphysema and
pulmonary fibrosis). When this is insufficient, the patient might require
mechanical ventilation.
Training
In the
United States, pulmonologists are physicians who, after receiving a medical degree
MD or
DO, complete residency training in internal medicine (3 years), followed by at least 2 additional years of subspeciality fellowship training in pulmonology. Most pulmonologists complete 3 years of combined subspecialty fellowship training in pulmonary medicine and critical care medicine.
In the
United States, pediatric pulmonologists are physicians who, after receiving a medical degree
MD or
DO, complete residency training in pediatrics (3 years), followed by at least 3 additional years of subspeciality fellowship training in pulmonology.

Scientific research
Pulmonologists are involved in both clinical and basic research of the
respiratory system, ranging from the anatomy of the bronchial epithelium to the most effective treatment of
pulmonary hypertension (a disease notoriously resistant to therapy).
