The wheezing symptom is episodic and the child is completely normal in between wheezing episodes. It has a good prognosis and only supportive treatment is required. Meanwhile, multi-trigger wheezing is associated with allergy and a family history of asthma. Symptoms occur in between wheezing episodes and are likely to persist beyond early ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds. [2]
This specific condition, in the general population, can vary between 7 and 20 percent. This increases to around 80 percent in those with symptomatic asthma. In many cases, however, the constriction, even during or after strenuous exercise, is not clinically significant except in cases of severe to moderate emphysema.
The main difference between VCD and asthma is the audible stridor or wheezing that occurs at different stages of the breath cycle: VCD usually causes stridor on the inhalation, while asthma results in wheezing during exhalation. [5] [6] [7] Patients with asthma usually respond to the usual medication and see their symptoms resolve.
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.
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 ...
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.
Asthma and viral bronchiolitis can also be nearly identical to each other when presented in very young children, since they both consist of wheezing, coughing, and nasal congestion. In addition, typical tests used to accurately diagnose children with asthma, such as the bronchial challenge test , are not considered to be accurate for children ...
