Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
High frequency chest wall oscillation (HFCWO) is an airway clearance technique recommended for respiratory management of neuromuscular conditions. This technique applies oscillations to the chest via a vest or wrap using an air pulse generator at a frequency of up to 20 compressions per second. These oscillations are thought to generate shearing forces and bias expiratory flow in the airways, facilitating secretion clearance. Participants will receive HFCWO regardless of their involvement in this study. Observational measurements will be taken for the duration of each physiotherapy intervention and repeated daily until discharge from PICU.
Intervention code [1] 317212 0
Not applicable
Comparator / control treatment
Standard physiotherapy treatment consisting of a combination of positioning, percussion, expiratory vibration, manually assisted cough, mechanically assisted cough and airway suctioning. These modalities may be used individually or together with the aim of optimising airway clearance. Participants will receive standard physiotherapy treatment regardless of their involvement in this study. Observational measurements will be taken for the duration of each physiotherapy intervention and repeated daily until discharge from PICU.

Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
