Emotional factors: it usually occurs when shortness of breath occurs after emotional excitement, and a large amount of carbon dioxide is exhaled, resulting in symptoms such as twitching and numbness of the limbs.

And advise the patient to use the method of breathing in a paper bag to inhale the exhaled gas repeatedly as a way to increase the amount of carbon dioxide inhalation; 2. Artificial mechanical ventilation: respiratory alkalosis occurs in the process of the patient’s treatment with artificial mechanical ventilation, and the symptoms can be relieved by re-adjusting the parameters of the ventilator.
