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 obstructionis a blockage of respirationin the airwaythat hinders the free flow of air. It can be broadly classified into being either in the upper airway(UPA) or lower airway(LOA). Airway obstruction is a life-threatening condition and requires urgent attention, and assistance when it is needed.[1] The assistance to clear an upper airway ...
An acute exacerbation of chronic obstructive pulmonary disease, or acute exacerbations of chronic bronchitis ( AECB ), is a sudden worsening of chronic obstructive pulmonary disease (COPD) symptoms including shortness of breath, quantity and color of phlegm that typically lasts for several days. It may be triggered by an infection with bacteria ...
Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by long-term 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 and/or exacerbations) due to abnormalities of the airways (bronchitis ...
Choking, also known as foreign body airway obstruction ( FBAO ), is a phenomenon that occurs when breathing is impeded by a blockage inside of the respiratory tract. An obstruction that prevents oxygen from entering the lungs results in oxygen deprivation. Although oxygen stored in the blood and lungs can keep a person alive for several minutes ...
Acute severe asthma. Silent chest, worsening symptoms despite use of medication. [1] Acute severe asthma, also known as status asthmaticus, is an acute exacerbation of asthma that does not respond to standard treatments of bronchodilators (inhalers) and corticosteroids. [2] Asthma is caused by multiple genes, some having protective effect, with ...
Gasping or choking during sleep. Fragmented sleep and restlessness. Dry mouth or sore throat upon waking. Unfortunately, that's not the end of it. The effects of sleep apnea can bleed into your ...
Respiratory arrest is a serious medical condition caused by apnea or respiratory dysfunction severe enough that it will not sustain the body (such as agonal breathing ). Prolonged apnea refers to a patient who has stopped breathing for a long period of time. If the heart muscle contraction is intact, the condition is known as respiratory arrest.
