Trial Review

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
The Oscar 2 is an automated device that has been shown to reliably and accurately measure mean pressures in the critically ill patient population. The performance of this device will be examined during aero-medical transportation of 15 patients.
Intervention code [1] 284535 0
Not applicable
Comparator / control treatment
Numeric integrated intra-arterial mean pressures recorded on the patient monitor have been shown to be interchangeable with high fidelity intra-arterial mean pressures, and as such, will be used as the reference standard against which to test Oscar 2 accuracy.
Control group
Active

Outcomes
Primary outcome [1] 286805 0
The agreement between invasive (reference) and non-invasive (test device) pressures. Numeric integrated intra-arterial mean pressures recorded on the patient monitor have been shown to be interchangeable with high fidelity intra-arterial mean pressures and will be used as the reference standard against which to test Oscar 2 accuracy.
Timepoint [1] 286805 0
A total of ten paired pressure measurements, invasive (reference) and non-invasive (test device), for each patient during aeromedical transportation
