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
Physiological waveforms will be recorded during anaesthesia and intensive care management including ECG, blood pressure, pulse oximetry, BIS, airway pressure and capnography. These will be recorded during care [up to 4 hours]. After deidentification they will be archived for future testing of signal processing algorithms.

During single acute care episode
Primary outcome [2] 305601 0
Set of digital recordings of blood pressure waveforms at .100Hz. for future exploratory algorithm development
Timepoint [2] 305601 0
During a single acute care episode.
Primary outcome [3] 305602 0
Set of recordings of digital pulse oximeter plethysmograph waveforms at .100Hz. for future exploratory algorithm development.
Timepoint [3] 305602 0
During a single acute care episode.
Secondary outcome [1] 345643 0
Set of recordings of digital capnograph waveforms. for future exploratory algorithm development. [Primary Outcome]
Timepoint [1] 345643 0
During a single acute care episode.
Secondary outcome [2] 345644 0
Set of recordings of digital Bispectral index [BIS] waveforms at .100Hz. for future exploratory algorithm development. The BIS waveform is a directly recorded electroencephalogram from a set of dermal electrodes on the forehead. [Primary Outcome]
Timepoint [2] 345644 0
During a single acute care episode.
Secondary outcome [3] 345783 0
Set of recordings of digital airway pressure waveforms from a continuous pressure sensor signal measured in the airway circuit near the patient. In addition to peak and trough pressures inspiratory and expiratory intervals will be explored for future algorithm development. [Primary Outcome]
Timepoint [3] 345783 0
During a single acute care episode

Statistical methods / analysis
This is an observational single group study aiming to develop a library of physiological waveforms. Analysis will be by testing a variety of signal processing algorithms rather than testing hypotheses or describing populations. Collection of data will occur by convenience until the maximum number is achieved. A power analysis is not appropriate.
