During a recurrence of bronchial asthma, symptoms such as wheezing, shortness of breath, chest tightness, and coughing occur. During an attack, the patient's chest often appears hyperinflated. Upon auscultation, scattered or diffuse wheezing sounds can be heard, primarily during expiration, and the expiration phase is also prolonged. However, in some severe asthma cases, wheezing sounds may not be present, a condition referred to as "silent chest," which should be noted. If an asthma attack cannot be relieved, it is important to seek medical attention promptly for management by a doctor.
