Introduction
Mechanical sputum removal improves lung function by promoting sputum expulsion, enhancing airway clearance, dilating airways, increasing respiratory rate, and improving pulmonary blood circulation through vibrations generated by a mechanical device. If you have any concerns or special medical conditions, it is recommended to consult professional healthcare providers. Additionally, maintaining healthy lifestyle habits and a positive mindset is also important.

Generally, mechanical sputum removal improves lung function by generating vibratory forces through a mechanical device, which promotes sputum expectoration, enhances respiratory tract clearance, dilates airways, increases respiratory rate, and improves pulmonary blood circulation. If there are any concerns or special medical conditions, it is recommended to consult professional healthcare personnel. Detailed explanations are as follows:

1. Promoting Sputum Expectoration: Mechanical sputum removal utilizes multidirectional vibration, compression, and directed drainage to expel sputum that has remained in the lungs or deeper airways for a prolonged period. This not only helps alleviate symptoms of dyspnea and coughing but also reduces the risk of pulmonary infection caused by sputum accumulation, thereby indirectly improving lung function.

2. Enhancing Respiratory Tract Clearance: Mechanical sputum removal stimulates lung tissue and increases mucus secretion, thus promoting the self-cleansing function of the respiratory tract. Improved self-clearance helps maintain airway patency, reducing retention of secretions in the respiratory tract and further enhancing lung function.

3. Airway Dilatation: The vibratory forces generated by mechanical sputum removal stimulate lung tissue and increase airway surface area, thereby dilating the airways. Airway dilation helps increase pulmonary ventilation and improve oxygenation.

4. Increasing Respiratory Rate: Mechanical sputum removal stimulates nerve endings in the lungs and chest, promoting contraction of respiratory muscles, thus increasing respiratory rate. A higher respiratory rate contributes to increased pulmonary ventilation and improved oxygenation.

5. Improving Pulmonary Blood Circulation: Mechanical sputum removal promotes local blood circulation and accelerates lymphatic return, helping to reduce edema and alleviate obstruction, thereby decreasing secretions and reducing pulmonary ventilation resistance. Additionally, improved blood circulation supplies lung tissue with adequate oxygen and nutrients, promoting repair and regeneration of lung tissue and further improving lung function.

In addition to receiving professional treatment, patients requiring mechanical sputum removal should also maintain healthy lifestyle habits and a positive mindset. For example, quitting smoking, avoiding air-polluted environments, and engaging in regular exercise can all help improve lung function and enhance quality of life.

What level of lung function is considered a contraindication for surgery?
A percentage of predicted FEV1 (forced expiratory volume in one second) below 60% or a significantly reduced FVC (forced vital capacity) may constitute contraindications for surgery. Pulmonary function parameters are crucial for assessing surgical risk; when these key indicators fall below the aforementioned thresholds, it indicates impaired ventilation and gas exchange functions, potentially leading to risks such as respiratory failure and infection during anesthesia and postoperative recovery.

Can lung function still improve at age 70 if it's poor?
Even at the age of 70, poor lung function can still be improved through scientific regulation. If reduced lung function is caused by factors such as chronic inflammation or improper breathing habits, and there is no severe organic lung disease, lung function can be enhanced to some extent by standard treatment to control underlying conditions and consistent breathing exercises. This approach strengthens respiratory muscles, improves ventilation efficiency, and helps alleviate symptoms such as shortness of breath and fatigue.

Can practicing deep breathing every day enhance lung function?
In general, whether practicing deep breathing daily can enhance lung function depends on the individual's physical condition and the method of practice. When performing deep breathing exercises, choose an environment with fresh air and avoid polluted or enclosed spaces. Each session should not be too long, and should be discontinued before fatigue sets in. Individuals with underlying lung diseases should consult a physician before beginning such exercises.

Is it necessary to undergo pulmonary function tests for difficulty in breathing?
Whether shortness of breath requires pulmonary function testing depends on the specific circumstances. If it is caused by transient, physiological factors, pulmonary function testing is usually unnecessary. However, if it results from persistent, pathological factors, pulmonary function testing is recommended. To reduce the occurrence of shortness of breath, it is important to maintain good indoor air circulation and avoid prolonged exposure to polluted or enclosed environments in daily life.

How to improve poor lung function
Poor lung function can be improved through various approaches: maintaining a balanced diet and consuming more foods that nourish the lungs; choosing aerobic exercises such as jogging and swimming; ensuring proper ventilation, avoiding smoking, and staying warm in daily life; practicing relaxation techniques like meditation to manage emotions; and, under medical guidance, using traditional Chinese herbs such as Astragalus (Huang Qi) and Fritillaria (Chuan Bei Mu). Maintaining regular作息 (作息 should be translated as "作息" is commonly used in Chinese to refer to daily routines or作息 habits which can be translated as "daily routines" or "作息" can be transliterated as "zuoxi" if needed for specific context, but here it's better to use natural English equivalent)作息 habits, and undergoing regular check-ups are essential for effectively improving lung function.

How Pulmonary Fibrosis Affects Lung Function
Pulmonary fibrosis affects lung function by restricting lung expansion, impairing oxygen diffusion capacity, disrupting the ventilation-perfusion ratio, reducing respiratory muscle efficiency, and increasing the risk of airway obstruction. Its pathophysiological mechanisms are closely related to parenchymal remodeling caused by collagen deposition. Pulmonary fibrosis causes the lung tissue to progressively lose elasticity, forming a "honeycomb lung" structure, leading to restrictive ventilatory dysfunction.

How to Improve Lung Function Through Breathing
Abdominal breathing is a deep breathing technique that increases lung ventilation by fully engaging the movement of the diaphragm. To practice, relax the body and assume a comfortable seated or supine position. Place one hand on the abdomen and the other on the chest. Inhale slowly through the nose, allowing the abdomen to rise and feeling it expand; then exhale slowly through the mouth, contracting the abdomen.

How Daily Exercise Can Improve Lung Function
Daily exercise can effectively improve lung function through various methods such as deep breathing exercises, aerobic activities, diaphragmatic breathing, balloon blowing, yoga, and equipment-based training. Deep breathing helps the lungs inhale and exhale air more fully, enhancing lung capacity. By inhaling deeply and then exhaling slowly, respiratory muscles are strengthened, thereby improving ventilatory efficiency.
