Symptoms Croup can strike throughout the year, but it is especially common in winter because the airways are easily constricted due to the cold weather, and once the diameter of the airways changes, a “swooshing” sound will be produced when breathing. If a baby has mild asthma, it is easier to cough in the morning after waking up or at night, and it will also have a short cough after exercise and running and jumping; if the symptoms are serious, the breathing will be wheezing all the time, and the exhaling and inhaling will be very loud, and even need to go to the hospital for medication. There are some minor differences between pneumonia and asthma. Both pneumonia and asthma have some difficulty in breathing, but in general, pneumonia is more difficult to breathe in, while asthma is a difficult exhalation type of breathing and a croupy sound in the lungs. There are many causes of asthma, but it is usually due to your own constitution and some external temptations. For example, if a baby has allergies and encounters external allergens, croup can be triggered. The most common trigger is infection, upper respiratory tract infection that leads to asthma. The initial symptoms of mild croup are similar to a cold, but a cold can heal on its own within 2 to 3 weeks. Prevention If allergies are suspected to be the cause of croup, you should first go to the hospital to investigate the allergens and try to keep your baby away from those allergens. Parents should clean regularly, try not to use the yellow bed, and buy mite resistant material for bed sheet and bed cover. If you are allergic to animal hair, you should avoid keeping long-haired pets such as dogs and cats. Family members should not smoke whether outdoors or indoors. Some mothers and fathers may think that they can protect their babies’ health by going outdoors to smoke and not letting them inhale second-hand smoke, but the harmful substances produced by smoking will remain on the smoker’s body, and when they touch the baby, they may get on the baby. Keeping the room temperature constant and the humidity not too high is also a good way to prevent your baby from getting asthma, because dust mites are more likely to grow in humid places. Once asthma is diagnosed, treatment is divided into two periods. When asthma is present, bronchodilators are usually given to the baby to ease the symptoms, in addition to some inhaled solids. In the recovery period, maintenance treatment is usually given with corticosteroids to make the airways more stable and the steroids can also help maintain the airways in addition to treatment.
