Is oxygen inhalation useful for bronchial asthma?
Administering appropriate oxygen therapy can have certain benefits for patients with bronchial asthma. The onset of bronchial asthma is mainly due to the edema of the bronchial mucosa and the constriction of the smooth muscles outside the bronchi leading to the narrowing of the lumen. This makes it difficult for gases to pass normally through the airway into the alveoli. Patients may experience symptoms such as coughing, chest congestion, breathlessness, or wheezing, which are primarily due to the pathophysiology of bronchial asthma. Of course, providing patients with appropriate oxygen therapy during an asthma attack can be beneficial, temporarily solving the problem of hypoxia. However, it is important to understand that asthma patients are not primarily suffering from a lack of oxygen but from ventilation dysfunction, which leads to the inability to expel carbon dioxide, the waste gas, from the body. Therefore, the fundamental treatment should focus on improving airway spasms and narrowing to enhance ventilation.
What to do about chest tightness in bronchial asthma?
Bronchial asthma is a disease characterized by breathlessness, chest tightness, rapid breathing, and coughing, caused by the infiltration of various inflammatory cells in the airways, resulting in the narrowing of the bronchial lumen and the production of a large amount of mucus. When patients with bronchial asthma experience chest tightness, we can treat them with some nebulized inhalation medications. These medications are usually short-acting bronchodilators that can take effect within 3-5 minutes, quickly alleviating the symptoms of chest tightness. Additionally, patients should avoid exposure to allergens that may trigger asthma attacks, such as animal fur, viruses, and dust, to prevent recurrence of the symptoms.
Does pulmonary hypertension require oxygen therapy?
Whether pulmonary arterial hypertension requires oxygen therapy primarily depends on the patient's blood oxygen saturation level at rest. Generally, it is recommended to measure the oxygen saturation for patients with pulmonary arterial hypertension. Due to intrapulmonary shunting and shunting between the left and right heart during pulmonary arterial hypertension, arterial and venous blood mix directly, resulting in very low blood oxygen saturation in patients. Generally speaking, if the measured blood oxygen saturation at rest is below 90%, such patients often need oxygen therapy. Even if it does not drop below 90%, patients with moderate to severe pulmonary arterial hypertension also require oxygen therapy. Oxygen therapy can improve hypoxia, significantly dilating the pulmonary vessels and thus alleviating symptoms of high pulmonary artery pressure. It is very valuable for improving patient prognosis and survival time.
Why is there a low fever after the flu?
Influenza, also known as the flu, is primarily due to an infection of the flu virus in our upper respiratory tract, leading to symptoms such as sore throat, cough, and fever. After the influenza virus enters the human body, it replicates repeatedly. Post replication, the body's immune cells attempt to eliminate it. However, it is usually challenging for immune cells to completely clear the virus in one go. Therefore, many patients experience a prolonged period of low-grade fever or persistent abnormal body temperature after the flu. Generally, the course of the flu is about 10-14 days, and recovery is typically achievable, often with a complete resolution of fever. Thus, there is no need for excessive worry. Treatment can be effectively enhanced by using a combination of antiviral Chinese and Western medicines.
What should I do if the flu recurs with fever?
Influenza, also known as the flu, refers to a disease characterized primarily by sore throat, cough, and fever, caused by an influenza virus infection of the upper respiratory tract during the flu season. Due to the repeated replication of the influenza virus after entering the human body, it triggers an immune response between the person and the virus, thus causing repeated fevers. However, for a person with normal immunity, the flu can improve on its own, usually over 7 to 10 days. During these 7 to 10 days, if the fever recurs, it can be managed with some antipyretic medicines. Both traditional Chinese medicine and Western medicine have relevant drugs. After the fever subsides, the flu can usually heal on its own within about 3 to 5 days. (Please use medication under the guidance of a doctor.)
How is the flu transmitted?
Influenza, also known as the flu, typically occurs when the human body is infected by influenza viruses, leading to associated symptoms. The symptoms of influenza can vary depending on the type of infecting pathogen or virus. Influenza is primarily transmitted from person to person or through contact with livestock and poultry. The main route of transmission is through droplets, such as when one comes into contact with droplets from a sneeze or cough of an infected person. Another possibility is through contact with birds or livestock, such as being infected by secretions or excretions from pigs, which is also a mode of transmission.
Characteristics of auscultation for bronchial asthma
Bronchial asthma, commonly known as asthma, is mainly a chronic airway inflammatory disease involving various inflammatory cells and their components. This condition causes the bronchi to narrow and spasm, hindering the passage of air through the airways into the alveoli. Since bronchial asthma primarily affects the smaller bronchi, expiratory wheezes or stridor can often be heard upon auscultation of the trachea. In severe cases, no sounds may be heard from the patient's lungs, a condition referred to as "silent lung," which is an indication of a serious progression of the disease.
How to test for asthma?
Asthma is fully referred to as bronchial asthma. It is primarily due to the presence of inflammatory cells in the airways over a long period of time. These inflammatory cells render the trachea highly reactive. With this hyperreactivity, patients often experience wheezing, shortness of breath, chest tightness, and coughing, which typically occur in the early morning and at night. These symptoms can generally be alleviated with or without medication, and if a patient typically exhibits these symptoms, an asthma diagnosis can essentially be made. However, if the symptoms are atypical, such as having only coughing or wheezing, it may be necessary to perform some pulmonary function tests, chest X-rays, ultrasounds, or electrocardiograms on the patient to rule out other diseases that could cause wheezing and coughing. Therefore, doctors will arrange for these tests based on the patient's symptoms.
Can you eat durian when you have a cold?
Wind-heat colds are not recommended for consumption. Traditional Chinese Medicine classifies colds into wind-heat colds and wind-cold colds based on the different external pathogenic factors patients experience. Wind-heat colds are primarily caused by exposure to external heat pathogens. Patients mainly exhibit symptoms including dry mouth, thirst, sweating, and coughing up phlegm, typically presenting with yellow phlegm. Durian is a food that tends to be warming; thus, consuming durian during a wind-heat cold could potentially worsen the condition or prolong the duration of the illness. Therefore, if the patient's symptoms match those described above for wind-heat colds, it is generally not recommended to eat durian. Of course, if the symptoms mentioned above are not present, eating durian is not a problem. Durian is a very nutritious food that can also aid in digestion. It is quite a good fruit.
Symptoms of bronchial asthma cough
Bronchial asthma, commonly referred to as asthma, often results in symptoms such as wheezing, shortness of breath, chest tightness, and coughing in patients. However, these symptoms do not always appear simultaneously in an individual. It's possible for a single symptom to serve as the initial manifestation of bronchial asthma. For example, the condition may present solely as wheezing, chest tightness, or, notably, as coughing, where it is the only symptom. The characteristics of asthma-related coughing primarily include a certain rhythmic pattern, typically worsening during early morning or late night, and it can easily lead to coughing up blood. Additionally, the coughing may begin and end abruptly and can be triggered by exposure to cold air or strange smells, followed by spontaneous improvement after a period. These are distinctive features of bronchial asthma coughing.
