Further study details as provided by Khon Kaen University:

Primary Outcome Measures:
  • secretion wet weight (gram) [ Time Frame: Three hours before, ten hours after treatment and night-time (02.00-07.00 am.) ]
    Airway mucus secretion was collected for three hours before and ten hours after treatment based on an auditory airway secretion sound and collected again at 02.00-07.00 am.The mucus secretion was collected by sterile suctioning technique via tracheostomy tube without adding any saline or sterile water.

  • viscosity of secretion [ Time Frame: Three hours before and after treatment ]
    The secretion were collected in three hours before and after treatment, It were measured viscosity by First The mucus was gently homogenized by tissue grinder 5 ml (Cw11-205, Cowie, UK) for six minute at 37 degree celsius Second using Micro-Oswald viscometers with a capillary diameter of 0.77 mm for viscosity measure at same temperature in each sample(before and after).

Secondary Outcome Measures:
  • Heart rate (beat/min) [ Time Frame: Before, during breathing exercise with device and immediate after treatment ]
    Heart rate was monitored before, during and immediate after breathing exercise with BreatheMAX (6-10 beats/set, 10 set/day and rest between ste for 1 minute)

  • Oxygen saturation (%SpO2) [ Time Frame: Before, during breathing exercise with device and immediate after treatment ]
    Oxygen saturation was monitored before, during and immediate after breathing exercise with BreatheMAX (6-10 beats/set, 10 set/day and rest between set for 1 minute)

  • Respiratory rate (times/min) [ Time Frame: In rest interval between set (1 minute) ]
    Respiratory rate was measured by manual for 1 minute before, rest interval between set and immediate after breathing exercise with device (during the patients reconnection mechanical ventilation)

Estimated Enrollment: 14
Study Start Date: August 2009
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: breathing exercise
BreatheMAX breathing device is Water pressure Threshold Bottle. The level of water in the cylinder determines the load for treatment. In the treatment using 20% PNIP (Peak negative inspiratory pressure) was performed with 6-10 breaths/set; 10 set/day
Device: BreatheMAX breathing device
