Is bronchial asthma dangerous?
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.
Symptoms of bronchial asthma
The most common symptoms of bronchial asthma are episodic difficulty in breathing, which can also manifest as episodic chest tightness and coughing. During an asthma attack, there will be accompanying wheezing sounds. If the patient is more severe, they may be forced to sit up to breathe during episodes of breathing difficulties, exhibiting orthopneic breathing. Some patients may experience a dry cough or cough up a large amount of white foamy sputum. In severe cases, symptoms of hypoxia such as cyanosis of the lips and nail discoloration can occur. Asthma attacks are generally acute, with symptoms appearing within minutes, but they can also begin more slowly, worsening over several hours or days. Asthma generally relieves itself, or even after relieving, it may recur, typically worsening during the night.
Complications of cor pulmonale
Complications of cor pulmonale commonly include several conditions. The first is pulmonary encephalopathy, caused by respiratory failure leading to hypoxia and carbon dioxide retention, which can cause somnolence in patients and, in severe cases, lead to coma. The second is acid-base imbalance and electrolyte disturbances. Cor pulmonale may present with various electrolyte disturbances, such as hyponatremia and hypokalemia. The third is arrhythmias, most commonly manifesting as atrial premature beats or paroxysmal supraventricular tachycardia. The fourth complication is shock. Shock is not very common in cor pulmonale, but if it occurs, the prognosis is poor.
What are the main signs of pneumothorax?
If it is a small amount of pneumothorax, the physical signs are generally not obvious, especially when patients with emphysema develop pneumothorax, it is difficult to detect any signs. However, when a larger amount of pneumothorax occurs, inspection will reveal that the affected side of the chest is bulging and respiratory movements are reduced. Upon palpation, the trachea usually shifts towards the healthy side, tactile fremitus on the affected side is reduced, percussion results in hyperresonance or tympany, and auscultation shows reduced breath sounds, which can disappear in severe cases.
