  2. Pulmonary drug delivery - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_drug_delivery

    Pulmonary drug delivery is a route of administration in which patients use an inhaler to inhale their medications and drugs are absorbed into the bloodstream via the lung mucous membrane. This technique is most commonly used in the treatment of lung diseases, for example, asthma and chronic obstructive pulmonary disease (COPD).

  3. Buteyko method - Wikipedia

    en.wikipedia.org/wiki/Buteyko_method

    The Buteyko method emphasizes the role of carbon dioxide and hyperventilation in respiratory diseases as well as overall health. It is known that hyperventilation can lead to low carbon dioxide levels in the blood (or hypocapnea), which can subsequently lead to disturbances of the acid-base balance in the blood and lower tissue oxygen levels.

  4. Metered-dose inhaler - Wikipedia

    en.wikipedia.org/wiki/Metered-dose_inhaler

    MDI canister and actuator components from H&T Presspart. A metered-dose inhaler consists of three major components: the canister, which is produced in aluminum or stainless steel by means of deep drawing, where the formulation resides; the metering valve, which allows a metered quantity of the formulation to be dispensed with each actuation; and an actuator (or mouthpiece) which enables the ...

  5. Pulmonary function testing - Wikipedia

    en.wikipedia.org/wiki/Pulmonary_function_testing

    Tidal volume: that volume of air moved into or out of the lungs during quiet breathing (VT indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.) FRC: Functional residual capacity: the volume in the lungs at the end-expiratory position: RV/TLC%

  6. Inhaler - Wikipedia

    en.wikipedia.org/wiki/Inhaler

    An inhaler (puffer, asthma pump or allergy spray) is a medical device used for delivering medicines into the lungs through the work of a person's breathing. This allows medicines to be delivered to and absorbed in the lungs, which provides the ability for targeted medical treatment to this specific region of the body, as well as a reduction in the side effects of oral medications.

  7. Lung volumes and capacities - Wikipedia

    en.wikipedia.org/wiki/Lung_volumes_and_capacities

    Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, [2] decreasing to 12–20 breaths per minute in adults. [3]

  8. Cheyne–Stokes respiration - Wikipedia

    en.wikipedia.org/wiki/Cheyne–Stokes_respiration

    Cheyne–Stokes respiration and periodic breathing are the two regions on a spectrum of severity of oscillatory tidal volume. The distinction lies in what is observed at the trough of ventilation: Cheyne–Stokes respiration involves apnea (since apnea is a prominent feature in their original description) while periodic breathing involves ...

  9. Nebulizer - Wikipedia

    en.wikipedia.org/wiki/Nebulizer

    In 1864, the first steam-driven nebulizer was invented in Germany. This inhaler, known as "Siegle's steam spray inhaler", used the Venturi principle to atomize liquid medication, and this was the very beginning of nebulizer therapy. The importance of droplet size was not yet understood, so the efficacy of this first device was unfortunately ...
