摘要：Introduction:This study aimed to investigate the cough strength and respiratory function as well as the factors affecting the cough strength of independent elderly people. Methods and Results: A total of 36 elderly people participated in this experiment, and two subjects with hypertension were excluded. All subjects were evaluated for vital capacity (VC), cough peak flow (CPF), and respiratory muscle strength by determination of the maximum inspiratory and expiratory pressure (PImax and PEmax, respectively) in a sitting position. Each measurement consisted of three trials, and the maximum values were adopted for the analysis. The average value of CPF was 291.5 ± 100.5 L/min. Moreover, 17 out of the 34 subjects had CPF P —0.64, P —0.40, P Conclusion: Elderly people who independently perform their activities of daily living do not always have high coughing ability and may have reduced VC associated with reduced coughing ability.
