Table 3 Treatment descriptors

From: Effects of treadmill exercise versus Flutter® on respiratory flow and sputum properties in adults with cystic fibrosis: a randomised, controlled, cross-over trial

  PR (bpm) SpO2 (%) Treatment descriptors
Control 81 ± 14 96 ± 3 resting breathing
Treadmill 129 ± 18 96 ± 3 5.4 km/h ± 0.7 at 3% incline ± 3, dyspnoea 3 ± 1, RPE 3 ± 2
Flutter® 84 ± 10 97 ± 2 7.3° ± 3.6 at 17.5 Hz ± 1.7, 31 cmH2O ± 10
  1. Data are presented as mean ± standard deviation for group values of the pulse rate (PR) and oxygen saturation (SpO2), and treatment descriptors (treadmill speed and incline, modified Borg dyspnoea [34] and modified 0-to-10-point rate of perceived exertion (RPE) [33]; Flutter® angle and oscillation frequency, average expiratory pressure). Treadmill work rate was set at the speed and incline equivalent to 60% of the participant’s peak VO2 achieved on Visit 1 of the study. Flutter® angle (positive numbers represent an inclination above the horizontal at 0°) was set at the inclination determined to be the most effective by the senior physiotherapist on Visit 1 of the study (i.e. that maximised the sensation of vibrations within the lungs)
