Effect of preceding inspiration method and cough timing on coughing power
- Conditions
- Obstructive ventilatory disturbance, Restrictive ventilatory disturbance
- Registration Number
- JPRN-UMIN000043290
- Lead Sponsor
- Gunma University
- Brief Summary
Compared to cough with an end-inspiratory pause after slow inspiration (method 4) significantly higher PCF was measured in cough without an end-inspiratory pause after rapid inspiration (method1), and in cough without an end-inspiratory pause after slow inspiration (method 3), in healthy subjects and patients with restrictive ventilation disorder. In addition, PCF was significantly higher in method 1 coughing compared to method 4 coughing in patients with obstructive ventilatory impairment.
