Objective testing should begin with spirometry at rest. In true exercise-induced bronchoconstriction, the results should be within normal limits. Should resting values be abnormal, then asthma, or some other chronic lung condition, is present.
Measuring pulmonary mechanics assesses the ability of the lungs to move huge volumes of air quickly through the airways to identify airway obstruction. [ citation needed ] The measurements taken by the spirometry device are used to generate a pneumotachograph that can help to assess lung conditions such as: asthma, pulmonary fibrosis, cystic ...
Obstructive lung disease is a category of respiratory disease characterized by airway obstruction. Many obstructive diseases of the lung result from narrowing (obstruction) of the smaller bronchi and larger bronchioles, often because of excessive contraction of the smooth muscle itself. It is generally characterized by inflamed and easily ...
Airway obstruction is a blockage of respiration in the airway that hinders the free flow of air. Airway obstructions can occur either in the upper airway or lower airway . The upper airway consists of the nose, throat, and larynx.
Acute respiratory distress syndrome (ARDS), a severe lung condition occurring in response to a critical illness or injury. Infant respiratory distress syndrome due to a deficiency of surfactant in the lungs of a baby born prematurely. Tuberculosis [4] Many cases of restrictive lung disease are idiopathic (have no known cause).
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
Airway obstruction can be caused by the tongue, foreign objects, the tissues of the airway itself, and bodily fluids such as blood and gastric contents . [ citation needed ] Airway management is commonly divided into two categories: basic and advanced .
Smothering is a mechanical obstruction of the flow of air from the environment into the mouth or nostrils, for instance, by covering the mouth and nose with a hand, pillow, or a plastic bag. [6] Smothering can be either partial or complete, where partial indicates that the person being smothered is able to inhale some air, although less than ...
