Correlation between TIV and PCF
cough, cough flow(PCF
Because TIV was significantly associated with the generated PCF during MI-E, the correlation between TIV and PCF was analyzed in terms of the applied position. TIV during voluntary cough showed a difference according to the position (Pearson correlation analysis with confidence intervals between the total insufflation volume (TIV) and peak cough flow(PCF).
