What are the symptoms of tracheitis?
Bronchitis is a very common disease in respiratory medicine and can be categorized into acute bronchitis and chronic bronchitis based on the duration of the disease. Generally, regardless of the type, the symptoms presented by patients are primarily discomfort in the respiratory tract, such as fever, fatigue, cough, expectoration, breathlessness, chest tightness, and wheezing in cases of acute bronchitis. For patients with chronic bronchitis during acute episodes, there generally is no fever, but the primary symptoms are persistent cough and expectoration, along with wheezing, breathlessness, and chest tightness. Additionally, symptoms may vary between the elderly and the young when they contract bronchitis, thus clinical symptoms are predominantly as described above.
Can pneumothorax measure lung capacity?
Pneumothorax is a very common type of disease, caused by many and complex factors. It is classified into three different types based on individual conditions, so different types of pneumothorax lead to different clinical symptoms and consequences for the patient. Usually, it is not advisable to measure lung capacity immediately after a pneumothorax occurs. For lighter cases, it is recommended to wait at least half a month before measuring lung capacity. If the pneumothorax is severe, the interval may need to be over a month before conducting lung capacity measurements. Therefore, while patients with pneumothorax can have their lung capacity measured, this should only be done once the condition is effectively managed.
How to treat dry cough caused by lung cancer?
Dry cough is a very common symptom in clinical practice, caused by many factors which are also very complex. Some patients might clearly have lung cancer. Due to the presence of lung cancer lesions, patients can experience irritating dry cough as well as symptoms like hemoptysis, chest pain, and chest tightness. It is possible that some patients do not exhibit symptoms of dry cough, perhaps due to other causes. Therefore, for dry cough, we need to identify if it is caused by lung cancer, as it often requires surgical treatment to control the symptoms. Some patients with minor lung cancer who experience dry cough might be able to control it with appropriate medications. However, to effectively control symptoms of dry cough caused by lung cancer, surgical removal is generally necessary and is the ultimate treatment plan.
Can influenza-specific drugs prevent influenza?
Influenza is a highly contagious respiratory disease caused by the invasion of the respiratory tract by influenza virus. Clinically, it can be divided into type A influenza and type B influenza based on the specific type of virus infection. Clinically, there are actually no specific drugs for influenza. The key is to provide appropriate antiviral medications for symptomatic treatment. For example, if a patient is infected with the influenza virus, commonly used treatments include traditional Chinese medicines or antiviral drugs, which can effectively alleviate the uncomfortable symptoms caused by the influenza virus. Regardless of which type of influenza virus the patient has, the medications used in clinical treatment cannot prevent influenza. Therefore, we recommend avoiding going out as much as possible during the peak season of influenza. If going out is necessary, it is important to take precautions, as influenza is transmitted through respiratory droplets. Wearing a mask when going outside can reduce the chances of getting infected with influenza.
Do common colds cause vomiting?
In clinical practice, the common cold can cause significantly different symptoms in patients due to various infecting pathogens. For instance, in addition to common symptoms like fever, nasal congestion, runny nose, sneezing, coughing, itchy throat, and pain, patients with a typical viral cold may also experience various degrees of gastrointestinal discomfort such as nausea, vomiting, abdominal pain, and diarrhea. Thus, when symptoms related to the gastrointestinal tract are present during a common cold, it is necessary to consider the possibility of a gastroenteric type of cold. Therefore, it is a common occurrence for vomiting to be induced by viral infections during a common cold. Prompt administration of rehydration, antiviral treatment, and symptomatic relief can effectively alleviate the vomiting symptoms caused by the common cold.
Will a cold with nasal congestion get better on its own?
Cold, also known as upper respiratory tract infection, manifests clinically in patients with varying degrees of nasal congestion, runny nose, and sneezing. It's important first to identify the upper respiratory tract infection, which is mainly caused by a viral infection that leads to symptoms like nasal congestion, runny nose, sneezing, and sometimes a sore throat. For viral infections causing inflammatory lesions in the respiratory tract, in cases where the patient's immune function is strong, the symptoms of nasal congestion caused by the viral cold can resolve on their own. However, in infants or elderly people with lower immune function, when a viral cold occurs, symptomatic treatment with antiviral drugs can lead to a quicker recovery.
Can the same medicine be taken for a cold from heat and a cold from cold?
The common cold is a very common upper respiratory tract infection. From the perspective of traditional Chinese medicine, patients are usually classified into hot-type colds and cold-type colds. Hot-type colds generally occur in the summer, while cold-type colds are more often caused by accidentally catching cold in the winter. For such patients, Western medicine may not show a clear distinction in symptoms and tends to be somewhat generic in medication use. However, in traditional Chinese medicine, distinguishing between cold and hot colds is very important in the treatment of upper respiratory tract infections. Therefore, when choosing medication treatment, Western drugs often do not differentiate much between hot and cold colds, while Chinese medicine treatments for colds vary significantly. For example, the most common cold treatment, Chai Hu formula, is divided into Chai Hu formula and proper Chai Hu formula. The Chai Hu formula is used for treating hot-type colds, while the proper Chai Hu formula is used for some cold-type colds. Thus, in clinical practice, some medications can treat both hot and cold colds, but some cannot.
Does common cold cause dry cough?
In clinical practice, ailments like the common cold, also known as upper respiratory infections, generally occur in patients due to reduced immune function, exposure to cold, or contraction of wind-cold, causing various symptoms such as nasal congestion, runny nose, sneezing, fever, dry and itchy throat, coughing, and pain. Therefore, as with the previous infection, most clinical cases are caused by viral infections. So, when patients suffer from upper respiratory infections, they often experience varying degrees of dry cough, which is very common. Typically, identifying the specific infecting pathogen causing the common cold and providing symptomatic treatment can lead to a full recovery within about a week. For severe dry cough symptoms, appropriate cough suppressant medications can be used for symptomatic treatment.
How to treat a cold with nasal congestion and dry cough?
The common cold is a very common inflammatory condition clinically, generally caused by viral infections, hence, the treatment for such patients usually needs to focus on antiviral medications. Most viral colds cause varying degrees of nasal congestion, runny nose, sneezing, and even dry cough and itchy throat among other clinical symptoms. For such patients, treatment begins by identifying the specific pathogens causing the cold. If it is a virus, timely administration of heat-clearing and detoxifying medications is necessary, along with the appropriate use of traditional Chinese medicine to alleviate symptoms like nasal congestion and runny nose. For symptoms such as nasal congestion and dry cough, appropriate use of cough suppressant medications or nebulized inhalation may be chosen to provide symptomatic relief, with treatment effects generally being ideal around three days.
Why can't patients with pulmonary embolism get out of bed?
Pulmonary embolism is a relatively common clinical disease, with many and complex inducing factors. The most common cause of pulmonary embolism in patients is due primarily to thrombi dislodging from the veins of the lower limbs or the pelvic deep veins, traveling through the bloodstream to the pulmonary arteries, thus causing the disease. Therefore, bed rest is essential during the acute phase of pulmonary embolism. The purpose of bed rest is to prevent further embolisms, to avoid the dislodging of pelvic or lower limb deep vein thrombi, which could lead to the formation of new thrombi. Therefore, for patients with pulmonary embolism, it is crucial to provide timely treatments such as thrombolysis to control the clinical symptoms caused by the pulmonary embolism effectively.
