The formation of COPD is usually a gradual process, usually after the age of forty, after the lung damage reaches a certain level, the obvious symptoms will not appear. It is mainly related to the patient's smoking history or working environment. Asthma is closely related to genetic factors and can develop from an early age. Some patients spontaneously relieve themselves as they age. Asthma is generally associated with a history of allergic rhinitis, eczema, and urticaria.
The continuous gas exchange of the respiratory system, the ability to resist the invasion of viruses and bacteria and the reserve function are very powerful. What we normally use for normal breathing, the lungs only need to use 10% of their functions to cope with. Therefore, slight lung injury does not bring obvious symptoms. When patients with COPD have cough, asthma and other manifestations, it means that the impairment of lung function has been more serious, and these symptoms will continue to exist and continue to aggravate; asthma is a temporary strong inflammatory response made by the airway to the stimulation of foreign substances, resulting in an acute attack of asthma due to airway obstruction, after the elimination of stimulation, the symptoms will also disappear.
Both COPD and asthma will have the symptom of expectoration. The sputum of patients with chronic obstructive pulmonary disease is mostly white mucilaginous, which is difficult to cough up. If there is a combination of infection, there will be purulent sputum. The sputum of asthma is caused by the eosinophil lysis caused by airway inflammation, which contains basic protein, so the sputum is crystal like, a little like boiling water When the lotus root powder is mixed with infection, there are transparent granules in the sputum, which will cause special asthma beads.
COPD and asthma also show their own physical signs during physical examination. The early symptoms of COPD patients were not obvious, the wheezing sound was not obvious during auscultation, and the wheezing sound was loud in asthmatic patients. Patients with chronic obstructive pulmonary disease have a long course of disease, will have obvious emphysema, barrel chest, costal space widened, percussion drum sound; asthma patients, stable period is not abnormal. There will be significant difference between the two in CT, pulmonary function or blood gas analysis.
There are different coping strategies between COPD and asthma. Chronic obstructive pulmonary disease (COPD) is a non-specific inflammation of the airway, which lacks effective anti-inflammatory measures. Therefore, the key is prevention. If symptoms have occurred, only control symptoms and alleviate pain. Allergic inflammation exists in the airway of asthmatic patients, which can be effectively controlled by inhalation of glucocorticoids, with the focus on anti-inflammatory, disease control and acute attack avoidance. Asthma patients can return to normal life through normal response; patients in the later stage of COPD have no recovery measures at present, so they can only reduce their pain as much as possible. Therefore, COPD patients should recognize the harm of the disease, find out in the early stage, exercise their lung function actively, and take measures when the disease seriously affects their life.
Chronic obstructive pulmonary disease (COPD) is a common disease in the respiratory system of the elderly, especially in the winter when the climate changes dramatically and the temperature drops abruptly, it is most likely to occur repeatedly due to upper respiratory tract infection, which brings many inconveniences to the life of the elderly. Therefore, once diagnosed as COPD, we must go to a doctor in time and take professional and standardized treatment. Patients with COPD insist on daily home oxygen therapy, at least 7-8 hours a day, mainly 5 liter oxygen concentrator, and must be equipped with oxygen concentration detection and temperature detection.
Home oxygen therapy:
How many liters of oxygen concentrator do COPD patients need?
Family oxygen therapy requires 3-10 L oxygen concentrator (depending on the condition). According to the relationship between the inhaled oxygen concentration and flow, only 41% of the oxygen in the patient's body is inhaled by the 5 litre oxygen concentrator, which is the value under ideal conditions. In fact, the oxygen inhaled by the 5 litre oxygen concentrator in the patient with chronic obstructive pulmonary disease is more than 30%, that is to say, the doctor said that the patient should use the oxygen with the low oxygen concentration of about 30 to discharge, which means that the 5 litre oxygen concentrator, whether the patient uses 3, 5 or 10 liters, depends on the patient's blood oxygen saturation The harmony degree is above 90% (generally 94%) as the goal. For example, if a patient with COPD uses a 5 liter machine but the blood oxygen saturation is below 90, then a large flow oxygen concentrator with a 5 liter or above should be used. Oxygen therapy time: 7-8 hours at least, many patient need more than 10 hours or more every day, Some patient which who are serious need more than 20 hours every day.
