Elderly people may be overworked, chronic obstructive pulmonary disease, bronchial asthma, diabetic ketoacidosis, heart failure and other causes of deep breathing and gasping for air. 1. Overexertion: the physical deterioration of the body functions of the elderly, overexertion, lack of rest, emotional stress and other situations may cause deep breathing gasping for air. 2. Chronic Obstructive Pulmonary Disease (COPD): Long-term chronic inflammatory airway disease, resulting in irreversible narrowing or even obstruction of the bronchial tubes of the elderly, resulting in pulmonary ventilation disorders, so the deep breathing and gasping for air. 3. Bronchial asthma: the elderly contact with pollen, dander, hair and other allergens induced bronchial smooth muscle contraction spasm allergic reaction, resulting in airway narrowing, ventilation is limited and deep breathing gasping for air. 4. Diabetic ketoacidosis: the elderly suffer from diabetes mellitus not correctly and reasonably control blood sugar, resulting in high blood sugar levels, acetoacetic acid and other ketone body synthesis increases, ketoacidosis, the body through the deep breathing gasping for gas to discharge excessive carbon dioxide. 5. Heart failure: the elderly heart failure due to the body circulation, pulmonary circulation stasis, the whole body tissue hypoxia ischemia and lead to deep breathing gasping atmosphere. Deep breathing and gasping for air in the elderly may be related to a variety of factors, it is recommended to consult a doctor for a clear diagnosis.
