A wheeze is a clinical symptom of a continuous, coarse, whistling sound produced in the respiratory airways during breathing. [1] For wheezes to occur, part of the respiratory tree must be narrowed or obstructed (for example narrowing of the lower respiratory tract in an asthmatic attack), or airflow velocity within the respiratory tree must be heightened.
Other causes can include acid reflux, asthma, allergies, or other chronic medical conditions, adds Richard Watkins, M.D., an infectious disease physician and professor of medicine at the Northeast ...
Current recommendations in acute asthma symptoms are utilization of diuretics such as furosemide, venodilators such as nitroglycerin, and morphine. [1] The initial strategy should focus on decreasing patient fluid retention with diuretic therapy, thereby decreasing cardiac preload and overall fluid load in pulmonary circuit ( pulmonary ...
With emphysema the shortness of breath due to effective bronchoconstriction from excessive very thick mucus blockage (it is so thick that great difficulty is encountered in expelling it resulting in near exhaustion at times) can bring on panic attacks unless the individual expects this and has effectively learned pursed lip breathing to more quickly transfer oxygen to the blood via the damaged ...
Asthma is a common condition and affects over 300 million people around the world. [3] Asthma causes recurring episodes of wheezing, breathlessness, chest tightness, and coughing, particularly at night or in the early morning. [4] Exercise-induced asthma is common in asthmatics, especially after participation in outdoor activities in cold weather.
Very severe acute asthma (termed "near-fatal" as there is an immediate risk to life) is characterised by a peak flow of less than 33% predicted, oxygen saturations below 92% or cyanosis (blue discoloration, usually of the lips), absence of audible breath sounds over the chest ("silent chest" : wheezing is not heard because there is not enough ...
It causes difficulty in breathing which ranges from mild to severe. Bronchospasms occur in asthma , chronic bronchitis and anaphylaxis . Bronchospasms are a possible side effect of some drugs: pilocarpine , beta blockers (used to treat hypertension), a paradoxical result of using LABA drugs (to treat COPD ), and other drugs.
Results suggested that women with asthma have a higher risk of preterm birth. [36] Researchers suggested that asthmatic episodes in pregnant women were associated with ongoing exposure to nitrogen dioxide and carbon monoxide - types of air pollutants. [36] Researchers also studied when women were most susceptible to develop asthma.
