Summary
Brief summary (as posted)
This study is a single-center, self-controlled trial. Patients will successively undergo voluntary coughing without intervention, a washout period, coughing stimulated by pressing the Tiantu acupoint, a washout period, and voluntary coughing without intervention. Vital signs of the patients before and after each cough will be recorded, as well as the changes in peak cough flow rate and intra-abdominal pressure after each cough. For peak cough flow rate and intra-abdominal pressure, three sets of data will be collected each time, and the best value will be taken. This pilot trial is conducted to verify the feasibility of the research design and to provide sample size estimation and data support for the main study.

- type
- EXPERIMENTAL
- label
- Pressing the Tiantu acupoint to stimulate coughing
- description
- At the end of the patient's inhalation, trained and qualified personnel with qualifications perform the compression. The right thumb or middle and index fingers are flexed and use the tips of the fingers to press on the patient's thyroid cartilage point (the thyroid cartilage point is located on the anterior midline of the neck, in the center of the supra-sternal fossa). Press vertically inward, with the tips of the fingers touching each other closely, aiming to cause itching in the throat. Stimulate the trachea to trigger a cough. The force should be at the minimum level that can produce a cough reflex. The pressure of the fingers is measured using a pressure gauge, which is 1.59 to 3.45 N. Each compression lasts for 4 seconds, with an interval of 5 minutes. Repeat this process 3 times (select the best value).

Primary outcomes (1)
- measure
- Cough peak expiratory flow rate at each time point
- timeFrame
- Baseline, during acupoint stimulation, and 30 minutes post-stimulation
- description
- The maximum expiratory flow rate generated in the airway when coughing forcefully and rapidly. Measured by a portable peak flow meter sealed at the patient's mouth during coughing. It is a crucial and objective quantitative indicator for evaluating cough efficiency and the strength of the expiratory muscles.
