  1. Sputum volume is the total volume for each 6-h period; high production refers to patients with a sputum production of more than 40 ml/day. NA, not applicable. Change in VO2 is the percentage change from previous period without P&PD. *, P < 0.05 versus manual turning periods. †, P < 0.001 versus manual turning periods. ‡, P < 0.05 versus times without P&PD.
