Pulmonology is considered a branch of [[internal medicine]], and is related to [[intensive care medicine]]. Pulmonology often involves managing patients who need life support and [[mechanical ventilation]]. Pulmonologists are specially trained in diseases and conditions of the [[chest]], particularly [[pneumonia]], [[asthma]], [[tuberculosis]], [[emphysema]], and complicated chest infections.<ref>{{cite journal|last=Sengupta|first=Nandini|author2=Sahidullah, Md|author3=Saha, Goutam|title=Lung sound classification using cepstral-based statistical features|journal=Computers in Biology and Medicine|date=August 2016|volume=75|issue=1|pages=118–129|doi=10.1016/j.compbiomed.2016.05.013|pmid=27286184}}</ref>

Pulmonology/respirology departments work especially closely with certain other specialties: [[cardiothoracic surgery]] departments and [[cardiology]] departments.

== History of pulmonology ==
One of the first major discoveries relevant to the field of pulmonology was the discovery of [[pulmonary circulation]]. Originally, it was thought that [[blood]] reaching the right side of the [[heart]] passed through small 'pores' in the [[Interventricular septum|septum]] into the left side to be oxygenated, as theorized by [[Galen]]; however, the discovery of pulmonary circulation disproves this theory, which had previously been accepted since the 2nd century. Thirteenth-century [[anatomist]] and [[physiologist]] [[Ibn Al-Nafis]] accurately theorized that there was no 'direct' passage between the two sides ([[Ventricle (heart)|ventricles]]) of the heart. He believed that the blood must have passed through the [[pulmonary artery]], through the lungs, and back into the heart to be [[circulatory system|pumped]] around the body. This is believed by many to be the first scientific description of pulmonary circulation.<ref>{{cite journal|author=Sharif Kaf A-Ghazal|date=2002|title=The discovery of the pulmonary circulation – who should get the credit: ibn Al-Nafis or William Harvey|url=http://www.ishim.net/ishimj/2/09.pdf|journal=Journal of the International Society for the History of Islamic Medicine|volume=2|page=46|access-date=2010-07-17|archive-date=2010-06-12|archive-url=https://web.archive.org/web/20100612141149/http://ishim.net/ishimj/2/09.pdf|url-status=live}}</ref>

=== Surgical procedures ===
Major surgical procedures on the heart and lungs are performed by a [[thoracic surgery|thoracic surgeon]].<ref>{{Cite web|url=https://www.healthcareers.nhs.uk/explore-roles/doctors/roles-doctors/surgery/cardiothoracic-surgery|title=Cardiothoracic surgery|date=2015-04-07|website=Health Careers|language=en|access-date=2019-01-25|archive-date=2019-01-26|archive-url=https://web.archive.org/web/20190126000937/https://www.healthcareers.nhs.uk/explore-roles/doctors/roles-doctors/surgery/cardiothoracic-surgery|url-status=live}}</ref> Pulmonologists often perform specialized procedures to get samples from the inside of the chest or inside of the lung. They use radiographic techniques to view vasculature of the lungs and heart to assist with diagnosis.

== Treatment and therapeutics ==
{{see also|Cardiothoracic surgery|Pulmonary rehabilitation}}

[[Medication]] is the most important treatment of most diseases of pulmonology, either by inhalation ([[bronchodilator]]s and [[steroid]]s) or in oral form ([[antibiotic]]s, [[leukotriene antagonist]]s). A common example being the usage of [[inhalers]] in the treatment of inflammatory lung conditions such as [[asthma]] or [[chronic obstructive pulmonary disease]]. [[Oxygen therapy]]<ref>{{Cite web|url=https://www.msdmanuals.com/en-au/home/lung-and-airway-disorders/rehabilitation-for-lung-and-airway-disorders/oxygen-therapy|title=Oxygen Therapy - Lung and Airway Disorders|website=MSD Manual Consumer Version|language=en-AU|access-date=2019-01-25|archive-date=2021-12-13|archive-url=https://web.archive.org/web/20211213053257/https://www.msdmanuals.com/en-au/home/lung-and-airway-disorders/rehabilitation-for-lung-and-airway-disorders/oxygen-therapy|url-status=live}}</ref> is often necessary in severe respiratory disease ([[emphysema]] and [[pulmonary fibrosis]]). When this is insufficient, the patient might require [[mechanical ventilation]].

Pulmonary rehabilitation<ref>{{Cite web|url=https://www.essentiahealth.org/services/pulmonary-medicine/rehabilitation/|title=Pulmonary Rehabilitation {{!}} Essentia Health {{!}} MN, ND, WI|website=www.essentiahealth.org|access-date=2019-01-25|archive-date=2019-01-26|archive-url=https://web.archive.org/web/20190126000943/https://www.essentiahealth.org/services/pulmonary-medicine/rehabilitation/|url-status=live}}</ref> has been defined as a multidimensional continuum of services directed to persons with pulmonary disease and their families, usually by an interdisciplinary team of specialists, with the goal of achieving and maintaining the individual's maximum level of independence and functioning in the community.

Interventions can include exercise, education, emotional support, oxygen, noninvasive mechanical ventilation, optimization of airway secretion clearance, promoting compliance with medical care to reduce numbers of exacerbations and hospitalizations, and returning to work and/or a more active and emotionally satisfying life. These goals are appropriate for any patients with diminished respiratory reserve whether due to obstructive or intrinsic pulmonary diseases (oxygenation impairment) or neuromuscular weakness (ventilatory impairment).  A pulmonary rehabilitation team<ref>{{Cite web|url=https://www.msdmanuals.com/en-au/home/lung-and-airway-disorders/rehabilitation-for-lung-and-airway-disorders/overview-of-pulmonary-rehabilitation|title=Overview of Pulmonary Rehabilitation - Lung and Airway Disorders|website=MSD Manual Consumer Version|language=en-AU|access-date=2019-01-25|archive-date=2019-01-26|archive-url=https://web.archive.org/web/20190126001142/https://www.msdmanuals.com/en-au/home/lung-and-airway-disorders/rehabilitation-for-lung-and-airway-disorders/overview-of-pulmonary-rehabilitation|url-status=live}}</ref> may include a rehabilitation physician, a pulmonary medicine specialist, [[physician assistant]] and allied health professionals including a rehabilitation [[nurse]], a [[respiratory therapist]], a [[Speech–language pathology|speech-language pathologist]], a [[physical therapist]], an [[occupational therapist]], a [[psychologist]], and a [[social worker]] among others. Additionally, breathing games are used to motivate children to perform pulmonary rehabilitation.

In the [[United States]], pulmonologists are physicians who, after receiving a medical degree ([[Doctor of Medicine|MD]] or [[Doctor of Osteopathic Medicine|DO]]), complete [[residency (medicine)|residency]] training in [[internal medicine]], followed by at least two additional years of subspeciality [[fellowship (medicine)|fellowship]] training in pulmonology.<ref>{{Cite web|url=https://www.acponline.org/about-acp/about-internal-medicine/subspecialties/pulmonary-disease|title=Pulmonary Disease {{!}} Internal Medicine Subspecialties {{!}} ACP|website=www.acponline.org|access-date=2019-01-25|archive-date=2015-09-09|archive-url=https://web.archive.org/web/20150909203508/https://www.acponline.org/patients_families/about_internal_medicine/subspecialties/pulmonology/|url-status=live}}</ref> After satisfactorily completing a fellowship in pulmonary medicine, the physician is permitted to take the board certification examination in pulmonary medicine. After passing this exam, the physician is then board certified as a pulmonologist.
