  Purpose

Mechanical devices to increase the individual's bronchial hygiene are commonly used in patients with chronic retention of secretions and abnormal cough reflex. In this clinical context a new technology (namely TPEP® - Temporary Positive Expiratory Pressure) has been recently developed with the aim to improve the respiratory condition in patients suffering from chronic respiratory diseases. This trial has the aim to assess the clinical efficacy of TPEP in patients with chronic hypersecretion and airways obstruction, but with a normal competence of the cough reflex

Primary Outcome Measures:
  • arterial oxygenation (as assessed by PaO2/FiO2 ratio and/or SatO2 index) [ Time Frame: Day 10 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Sputum volume [ Time Frame: Day 1 to 10 ] [ Designated as safety issue: No ]
  • Sputum characteristics [ Time Frame: Day 1 to 10 ] [ Designated as safety issue: No ]
  • Individual's perceived sensation (VAS scale) [ Time Frame: Day 1 to 10 ] [ Designated as safety issue: No ]
  • Lung function (volumes and respiratory muscle performance) [ Time Frame: Day 1 - 3 - 10 ] [ Designated as safety issue: No ]

Enrollment: 100

Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
TPEP added to conventional manually assisted breathing techniques (MABT)
Device: TPEP device (UNIKO)
This technique is mainly based on a continuous low-pressure insufflation in the airways, which is likely to reduce (or even avoid) the potential pressure-related damages of other commonly used devices. This device should be used only in those individuals who are showing a normal competence of their cough reflex, thus it should be considered as a means which may help those techniques normally adopted for the individual's bronchial hygiene.
Other Name: UNIKO
Active Comparator: 2
Manually assisted breathing techniques (MABT) alone
Procedure: MABT (Manually assisted breathing techniques)
Conventionally manually assisted breathing techniques
Other Name: MABT

Detailed Description:

This is a single-blind multicentre controlled randomized trial with consecutive recruitment. Randomization list by blocks will be available. Group comparison will be made between active therapies including TPEP added to conventional MABT (Intervention) or MABT alone (Control). Active therapy will last 10 consecutive daily sessions in both groups.

Primary outcome

Efficacy comparison on change in:

a.arterial oxygenation (as assessed by PaO2/FiO2 ratio and/or SatO2 index)

Secondary outcomes

Efficacy comparison on change in:

  1. Sputum characteristics
  2. Daily sputum volume
  3. Perceived sensation
  4. Lung functions (as assessed by spirometry and RM strength)
