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 ...
Other names. Hypoxaemia. Blood with higher oxygen content appears bright red. Specialty. Pulmonology. Hypoxemia is an abnormally low level of oxygen in the blood. [ 1][ 2] More specifically, it is oxygen deficiency in arterial blood. [ 3] Hypoxemia has many causes, and often causes hypoxia as the blood is not supplying enough oxygen to the ...
Asthma is a long-term inflammatory disease of the airways of the lungs. [ 4 ] It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. [ 9 ][ 10 ] Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. [ 3 ]
Cardiac asthma is the medical condition of intermittent wheezing, coughing, and shortness of breath that is associated with underlying congestive heart failure (CHF). [ 1] Symptoms of cardiac asthma are related to the heart's inability to effectively and efficiently pump blood in a CHF patient. [ 2] This can lead to accumulation of fluid in and ...
Acute respiratory distress syndrome ( ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. [ 1] Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis). [ 1] For those who survive, a decreased quality of life is common.
Respiratory failure. Respiratory failure results from inadequate gas exchange by the respiratory system, meaning that the arterial oxygen, carbon dioxide, or both cannot be kept at normal levels. A drop in the oxygen carried in the blood is known as hypoxemia; a rise in arterial carbon dioxide levels is called hypercapnia.
Hypopnea is typically defined by a decreased amount of air movement into the lungs and can cause oxygen levels in the blood to drop. It commonly is due to partial obstruction of the upper airway. Hypopnea during sleep is classed as a sleep disorder. With moderate to severe hypopnea, sleep is disturbed such that patients may get a full night's ...
What is a good oxygen level? “Normal people who have working lungs, and all those steps are going well, their blood oxygen level will usually be 96-100 percent,” adds Dr. Uppal. A few notches ...
