About this study

Official title: Reducing Oxygen Consumption in Critical Care (ROCC)

In normal practice oxygen supply can be easily met with existing hospital infrastructure. COVID - 19 however results in lung damage which greatly increases the amount of oxygen patients require - as a consequence some hospitals in the UK and other countries had situations where there was not enough oxygen for their inpatients.

COVID - 19 has caused many more patients to requiring assistance with their breathing using a ventilator. Due to the limited supply of sophisticated ventilators that 're-use' oxygen patients breathe out, some hospitals have used ventilators normally used by patients at home (domiciliary ventilators). Whilst these are inexpensive and commonly available, any oxygen the patient breathes out is simply released into the atmosphere.

The address this problem, and in turn reduce the oxygen demand on hospital infrastructure the biomedical engineering team (BME) at the Royal Brompton Hospital, London devised a simple 3-D printed modification which captures and reuses oxygen on commonly used domiciliary ventilators. Laboratory testing found this modification can increase the oxygen given by the ventilator without increasing the oxygen consumption of the ventilator - effectively reducing oxygen demand on hospital infrastructure.

This study will evaluate this modification in patients admitted to intensive care requiring assistance with their breathing. This will involve measuring oxygen levels on domiciliary ventilators (Breas Nippy 4+, ResMed Lumis 150 or Vivo 1, 2 or 3) with and without the modification and with small increases in oxygen supplied to the patient for a total study period of 2 hours.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ventilator modificationDevice

    The ventilator modification will be fitted to a ResMed Lumis 150, Breas® Nippy 4+ or Vivo 1, 2 or 3 ventilator. The participants oxygen level will be measured with and without the modification in place at their baseline ventilation, and with 1, 2 and 3 litres oxygen extra to their baseline. the researcher will then leave the modification on and slowly reduce the oxygen going into the ventilator, maintaining the participants SP02 at an acceptable level (>95%)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Arterial blood gas analysis - baseline

    PaO2 with and without modification fitted

    Measured: After 10 minutes

Secondary outcomes (2)
  1. Arterial blood gas - modification and oxygen change

    Oxygenation with and without modification in place with 1, 2 and 3 litres added to baseline FiO2

    Measured: After 10 minutes of each experimental condition

  2. Arterial blood gas - CO2

    Arterial CO2 levels at each experimental condition

    Measured: After 10 minutes of each experimental condition

Questions about this trial

What is this clinical trial studying?

An observational study of Mechanical Ventilation Complication, run by Royal Brompton & Harefield NHS Foundation Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Nov 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Arterial blood gas analysis - baseline (time frame: After 10 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Nov 2023.
