Pressing the Tiantu acupoint to stimulate coughing
Pressing the Tiantu acupoint to stimulate coughing: At the end of inhalation, press the Tiantu acupoint to stimulate coughing. The specific operation method has been mentioned earlier.
Study summary
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.

Primary outcome measure(s)
Cough peak expiratory flow rate at each time point — Baseline, during acupoint stimulation, and 30 minutes post-stimulation 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.
