Whether bronchial asthma is dangerous depends on the severity of the condition during an acute asthma attack. The most common symptoms of asthma are episodic breathing difficulties, chest tightness, or coughing. If the patient experiences only mild breathing difficulties during an acute attack, it may resolve on its own without posing a life-threatening risk. However, if it is a severe asthma attack, such as the patient being unable to speak, experiencing drowsiness, consciousness disorders, even showing paradoxical movement, weakened wheezing sounds, or even an absence of breathing sounds, then there may be a life-threatening risk if immediate and aggressive rescue measures are not taken.
