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.
Patients may experience dizziness, heart palpitations, hyperglycemia, diarrhea and muscle cramps when taking these medications. Importantly, medications that antagonize the β2 receptor (β-blockers) may significantly increase the risk of asthma exacerbations, and are generally avoided in asthmatic patients. [7]
Asthma phenotyping and endotyping has emerged as a novel approach to asthma classification inspired by precision medicine which separates the clinical presentations of asthma, or asthma phenotypes, from their underlying causes, or asthma endotypes. The best-supported endotypic distinction is the type 2-high/type 2-low distinction.
“Wheezing is found in more than a third of people with RSV, even if you don’t have asthma,” he says. If you have COPD or asthma, he adds that RSV could cause a flare-up. “Sinus infections ...
The most common signs and symptoms of an asthma attack include coughing, shortness of breath, feeling winded, a tightening in the chest, and a wheezing that makes a high-pitched whistling sound ...
When the airways spasm or constrict in response to the irritating stimulus of the breathing tube, it is difficult to maintain the airway and the patient can become apneic. During general anesthesia, signs of bronchospasm include wheezing, high peak inspiratory pressures, increased intrinsic PEEP , decreased expiratory tidal volumes, and an ...
