肺功能吹气操作流程

肺功能吹气操作流程
English Answer:
Pulmonary Function Test Procedure.
Indications:
To assess lung function.
To diagnose and monitor respiratory diseases.
To evaluate the effectiveness of treatments.
Preparation:
Patient should be informed about the procedure and its importance.
Patient should be asked to refrain from eating or exercising for at least 4 hours prior to the test.
Patient should remove any tight clothing or jewelry around the chest and neck.
Patient should sit in a comfortable position, with
their back straight and their feet flat on the floor.
Procedure:
1. Spirometry: Patient breathes into a mouthpiece attached to a spirometer, which measures the volume and
flow of air during inhalation and exhalation.
2. Lung Volumes: Patient breathes into a sealed chamber, which measures the volume of air in the lungs.
3. Diffusion Capacity: Patient breathes a mixture of gases, and the amount of gas that diffuses across the lungs is measured.
4. Bronchodilator Response: Patient inhales a bronchodilator and then undergoes spirometry to assess the
reversibility of airflow obstruction.
Interpretation:
The results of pulmonary function tests are interpreted in the context of the patient's symptoms, medical history, and other clinical findings. The results can help to diagnose and monitor respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis.
Important Notes:
The procedure is non-invasive and painless.
It is important for the patient to cooperate fully with the instructions during the procedure.
The results of the test may be affected by the
patient's effort and technique.
The test may be repeated over time to monitor changes
in lung function.
中文回答：
肺功能吹气操作流程。

适应症：
评估肺功能。

诊断和监测呼吸系統疾病。

评估治疗效果。

准备：
告知患者检查目的及重要性。

要求患者在检查前至少 4 小时内禁食和剧烈运动。

患者脱去胸部和颈部的紧身衣物或饰品。

患者舒适就座，背部挺直，双脚平放于地面。

过程：
1. 肺活量测定，患者向连接肺活量测定仪的吹口呼气，该仪器
可测量吸气和呼气过程中的气体容积和流量。

2. 肺容积，患者向密闭舱内呼吸，该舱室可测量肺部气体容积。

3. 弥散容量，患者吸入混合气体，测量通过肺部弥散的气体量。

4. 支气管扩张反应，患者吸入支气管扩张剂，然后进行肺活量
测定以评估气道阻塞的可逆性。

结果解读：
肺功能检查结果应结合患者症状、病史和其他临床表现进行解读。

结果有助于诊断和监测哮喘、慢性阻塞性肺疾病 (COPD) 和肺
纤维化等呼吸系統疾病。

注意事项：
该检查无创无痛。

患者在检查过程中必须完全配合医生的指示。

患者的努力程度和技术可能会影响检查结果。

可能会随时间重复该检查以监测肺功能的变化。
