Asthma is an inflammation and obstruction of the bronchial tubes - the passages that allow air to enter and leave the lungs. During an asthma attack, the muscles that surround the bronchial tubes constrict, narrowing the air passages and making it extremely difficult to breathe. There is often a feeling of tightness and a wheezy or rattling sound in the chest.
Asthma attack signs and symptoms include: Severe shortness of breath, chest tightness or pain, and coughing or wheezing, Low peak expiratory flow (PEF) readings, if you use a peak flow meter, Worsening symptoms despite use of a quick-relief (rescue) inhaler. Some people with asthma may go for extended periods without having an asthma attack or other symptoms, interrupted by periodic worsening of their symptoms,
Although acute asthma is a very common cause of emergency department visits of children and adults, there is not as yet a standardized accepted treatment protocol. Oxygen is the first treatment the patient needs in order to overcome hypoxemia. Beta-2 agonists should always be given with oxygen in order to prevent the decrease in oxygen saturation due to the increase of blood flow in relatively poor ventilated areas of the lung.
