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 ...
Rates of asthma rates in 2017 [1] As of 2011, approximately 235 million people worldwide were affected by asthma, [2] and roughly 250,000 people die per year from asthma-related causes. [3] Low and middle income countries make up more than 80% of the mortality. [4] Prevalences vary between countries from 1% to 18%. [3]
It occurs in most people with asthma and up to 20% of people without asthma. [116] Exercise-induced bronchoconstriction is common in professional athletes. The highest rates are among cyclists (up to 45%), swimmers, and cross-country skiers. [117] While it may occur with any weather conditions, it is more common when it is dry and cold. [118]
Since pneumonia can take a dangerous turn, it's important to know the earliest signs of it. Dr. Zweig says that, typically, pneumonia starts as a regular viral upper respiratory infection.
AERD affects an estimated 0.3–0.9% of the general population in the US, including around 7% of all asthmatics, about 14% of adults with severe asthma, and ~5-10% of patients with adult onset asthma. [2] [3] [8] AERD is uncommon among children, with around 6% of patients, predominantly female, reporting disease onset during childhood. [9]

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.
In most people, these other immune cells (T H 0 cells) "check" and usually ignore the allergen molecules. In asthma patients, however, these cells transform into a different type of cell (T H 2), for reasons that are not well understood. A possible reason could be the release of Interleukin-4 by Mast cells that induce differentiation of naive ...
