Reference excerpt

Ancient period 1550 BC: (EG) The Ebers Papyrus describes ancient Egyptian inhalation treatments for asthma.

Eighteenth Century (1700s) 1771: (US) Carl Scheele (1742–1786) makes "fire air" (oxygen) by heating magnesium oxide. His findings are published in June 1774. 1774: (US) Joseph Priestley (1733–1804), credited with the discovery of oxygen, publishes his work on "dephlogisticated air" oxygen 3 months after a report by Carl Scheele.

Nineteenth Century (1800s) 1816: (US) Rene T.H. Laennec (1776–1856) invents the stethoscope for chest auscultation and lays the foundation for modern pulmonology with his book Diseases of the Chest. 1860: (US) Bunsen and Kirchhoff invent the spectrometer. 1860: (US) Stokes and Hoppe-Seyler demonstrate the oxygen transport function of hemoglobin. 1897: (DE) Gustav Killian performs the first bronchoscopy in Germany. 1899: (US) Dr. Thomas Willis defines specific Asthma symptoms for diagnosis.

Twentieth Century (1900s)

1900-1920 1908: (US) George Poe demonstrated his mechanical respirator by asphyxiating dogs and seemingly bringing them back to life. 1918: Oxygen masks are used to treat combat-induced pulmonary edema.

1920-1940 1928: Phillip Drinker develops the "iron lung" negative pressure ventilator. 1935: Carl Matthes invented the first noninvasive oximeter employing an ear probe.

1940-1960 1943: Dr. Edwin R. Levine, MD began training technicians in basic inhalation therapy for post-surgical patients. 1946: (US) Dr Levine and his technicians formed the Inhalation Therapy Association. 1954: (US) March 16, 1954 the ITA is renamed the American Association of Inhalation Therapists (AAIT). 1966: (US) February 1966, the ITA was again renamed the American Association for Inhalation Therapy (still, AAIT). 1956: (US) The AAIT begins publishing a science journal, Inhalation Therapy (now RESPIRATORY CARE). 1960: (US)In October 1960 The American Registry of Inhalation Therapists (ARIT) is formed to oversee examinations for formal credentialing for people in the field.

1960-1980 1961: (US) Sister Mary Yvonne Jenn becomes the first Registered Respiratory Therapist 1961: Metaproterenol, the beta-2 bronchodilator is introduced. 1964: (CA) The Canadian Society of Respiratory Therapists (CSRT) is founded in 1964 as the Canadian Society of Inhalation Therapy Technicians. 1970: (US) In 1970 The Board of Schools of Inhalation Therapy Technicians became the Joint Review Committee for Respiratory Therapy Education (JRCRTE). 1971: (US) Continuous positive airway pressure (CPAP) is introduced by Gregory. 1971: (US) The journal Inhalation Therapy is renamed to Respiratory Care. 1974: (US) The two US credentialing programs merge into a single credentialing organization called the National Board for Respiratory Therapy (NBRT) in 1974. 1980: (US) President Jimmy Carter proclaimed the first Cystic Fibrosis Awareness Week. (July 22)

1980-2000 1982: (US) California passes the first modern licensure law governing the profession of respiratory care. 1982: (US) In 1982 President Ronald Reagan proclaimed the first National Respiratory Care Week. 1986: (US) In 1986 the NBRT is renamed the National Board for Respiratory Care (NBRC). 1998: (US) The JRCRTE evolves into the Committee on Accreditation for Respiratory Care (CoARC).

Twenty-First Century (2000s) 2000: (US) Respiratory Care journal is accepted into Index Medicus and its online counterpart, the MEDLINE service. 2004: (US) Vermont becomes the 48th state to pass a Respiratory Care Act, effectively bringing legal credentialing to all 48 contiguous states in the United States. 2010: (US) On December 14, 2010, the National Commission for Certifying Agencies (NCCA) grants accreditation to the Sleep Disorders Specialty Examination. The CRT-SDS and RRT-SDS. 2011: (US) In July, 2011 the NBRC creates the Adult Critical Care Specialty for Registered Respiratory Therapists (RRT-ACCS). 2011: (US) In 2011 the State of Hawaii became the 49th state in the United States to create a Board of Respiratory Care and enacting a Respiratory Care Act. 2012: (US) In April, 2012 the Office of Regulation in the State of Michigan recommends the de-regulation of the respiratory therapy profession. The report, seemingly with its head in the sand as regards respiratory care, concluded de-regulation would "eliminate unnecessary oversight [and remove regulation providing] no value to the citizens of Michigan."

Worked examples

Example 1 — a first encounter with Timeline of respiratory therapy

Start with the simplest possible case. Write down what Timeline of respiratory therapy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Timeline of respiratory therapy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Timeline of respiratory therapy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Timeline of respiratory therapy

In research: Timeline of respiratory therapy appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Timeline of respiratory therapy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Timeline of respiratory therapy is common in secondary-school and first-year university syllabi. It links to neighbouring topics Medicine timelines, Pulmonology, Respiratory therapy, so understanding it makes those chapters shorter.
In everyday life: Look for Timeline of respiratory therapy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
