Changes in cardiovascular physiology during high frequency chest wall oscillation (HFCWO) for 5, 10, and 15 minutes and 15 minutes after sputum suction and during conventional chest physiotherapy (CCPT) for 15 minutes and 15 minutes after sputum suction. Each solid symbol indicates the mean of each variable at each time point of the HFCWO group; each open symbol indicates the mean of each variable at each time point of the CCPT group; bars indicate standard error (SE); within-group comparisons to the baseline: all P > 0.05 except ∗P < 0.05, between-group comparisons: ^P < 0.05, ^^P < 0.01, +P = 0.06; BL = baseline, BP = blood pressure, upside down triangle indicates sputum suction.
