Asthma affects the functioning of the lungs and the entire respiratory system. As discussed in category 1, the nose is the portal to our body’s airway, allowing us to breathe clean, filtered, and humidified air. Once air is processed by the sinuses, it moves toward the lungs through the trachea (3, page 32). The trachea
divides into two branches, or bronchi, each feeding into one of the lungs. Within each lung, the bronchi further divide into thousands of smaller branches, forming the bronchial tree. Each branch is surrounded by rings of muscles that constrict and relax in response to various stimuli as we breathe, allowing air to flow freely.
The air we inhale then travels to the tips of the bronchial tree and eventually reaches the alveolus, where the exchange of oxygen and carbon dioxide takes place among the network of blood vessels that surround it. The bronchi and alveoli are lined with their own mucous membranes, which perform the same filtering and humidifying functions as the ones in our nose and mouth.
Asthma related to allergies and CAID can be controlled, and often prevented, through avoidance and education. If you can recognize your triggers, as well as your trigger symptoms,
Children usually experience complete remission from asthma more frequently than adults do. Between 30 and 70 percent of children who develop asthma either improve or are totally as
Women with asthma used to be discouraged from becoming pregnant, but advances in medication have made pregnancy extremely possible. Yet like all other aspects of pregnancy, it can
During an acute attack, it is necessary to administer oxygen continuously until the flare-up is completely over. As described earlier, during an asthma flare-up, your oxygen levels
Steroids in an oral or intravenous form are used to treat a range of asthma attacks. Their role is to reduce the inflammation of the bronchial tube’s lining, thus reducing the ac
Quick-relief medications relax the muscles around the bronchial tubes so that air can flow freely through them. As noted earlier, these medications are called bronchodilators or be
