If the elderly in the home environment, symptoms of breathlessness, breathing difficulties, family members should first call the emergency vehicle to send the elderly to the hospital for treatment, in the time waiting for the arrival of the emergency vehicle, you can first according to the past medical history of the elderly to simply determine the cause, and then take some simple first aid means, to the hospital and then perform targeted treatment. The following is the treatment of several common clinical situations, but can not represent all cases: 1, cardiogenic dyspnea: generally acute heart failure, in most cases, such patients are suffering from hypertension, coronary heart disease or kidney disease. Patients with hypertension or coronary artery disease tend to develop after poor blood pressure control or exertion; patients with kidney disease tend to develop after excessive fluid intake. If dyspnea is considered to be caused by heart failure, the patient can be asked to choose a sitting position while both lower limbs are lowered to reduce the blood volume of the heart and lungs to relieve certain symptoms of dyspnea. Upon arrival at the hospital, oxygen therapy needs to be given. If the patient’s blood pressure is found to be elevated, oral antihypertensive drug therapy, such as captopril and nitroglycerin, can be considered under the guidance of a doctor. 2. Pneumonia: dyspnea due to pneumonia is mostly seen in elderly people who are bedridden for a long time, especially in patients with sequelae of cerebrovascular disease. As such patients are prone to aspiration pneumonia, but because the choking reflex is not obvious, it cannot be detected in time, and by the time symptoms of respiratory distress appear, most of them have already suffered respiratory failure. At this time, family members should pay attention to keep the patient’s airway open, prevent the tongue from falling back, and promptly remove food and secretions from the mouth. If the dyspnea is diagnosed to be caused by pleural effusion, drainage treatment is also required; 3. Chronic obstructive pulmonary disease: The dyspnea caused by the acute attack of chronic obstructive pulmonary disease is due to the obstruction of carbon dioxide expulsion caused by small airway spasm, which is especially common in the north. Relieving the airway spasm is the key to treating this disease, at this time, the usual application of wheezing aerosol inhalation can be considered. Upon arrival at the hospital, low-flow oxygen therapy needs to be given, and care should be taken not to give high-flow oxygen to prevent paralysis of the respiratory center and coma of the patient. In addition, if there is a history of bronchial asthma, salbutamol inhalation therapy may be applied. At the same time, there may also be other reasons why the elderly cannot breathe. After the arrival of the emergency vehicle, the patient must be sent to the hospital to perform electrocardiogram, blood gas analysis, blood routine and other related diagnoses to clarify the cause and then carry out targeted treatment.
