Study phase:

N/A

研究设计:

单臂 

Study design:

Single arm 

研究目的:

1.评估诱导排痰技术对慢性咳嗽患者患者生命体征(心率、呼吸、指脉氧)的影响; 2.分析诱导排痰的一次性留取成功率(痰量>2ml且鳞状上皮细胞<20%); 3.记录不良反应(恶心呕吐、咽喉不适等)发生率; 4.评价患者对操作流程的满意度; 5.操作安全性。  

Objectives of Study:

1. Evaluate the impact of induced sputum production techniques on vital signs (heart rate, respiration, pulse oximetry) in patients with chronic cough; 2. Analyze the success rate of single collection of induced sputum (sputum volume>2ml with squamous epithelial cells <20%); 3. Record the incidence of adverse reactions (nausea, vomiting, throat discomfort, etc.); 4. Assess patient satisfaction with the procedural workflow; 5. Operational safety.
