| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
| Patients admitted to the intensive care unit who are in the recovery phase of their illness and are weaning from mechanical ventilation. |
|
| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
This is a study to look at whether breathing Helium (which being much lighter than air is easier to breathe) and oxygen makes breathing easier for patients, and therefore enables them to be helped off the support provided by breathing machines (ventilator) in their recovery phase in the intensive care unit. |
|
| E.2.2 | Secondary objectives of the trial |
To measure a number of physical signs in the patient such as heart rate, rate of breathing and to see if breathing the Helium−oxygen mixture makes breathing more easy. |
|
| E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
| E.3 | Principal inclusion criteria |
Patient will be defined as ready for weaning with CPAP if Failed a spontaneous breathing trial Pressure support ventilation < 10cmH2O Underlying respiratory failure improving No upper airway obstruction or bronchospasm Not receiving continuous IV sedation Not receiving vasoactive agents FiO2 < 0.4 and PEEP< 10 cm H2O and Fully conscious
|
|
| E.4 | Principal exclusion criteria |
Inadequate analgesia Pregnancy Participation in other intervention trials in the past 30 days Refusal of consent from the patient or assent from the next of kin
|
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
The primary endpoint will be CO2 production, a recognised measure of work of breathing during weaning.

visit of the last subject undergoing the trial
|
Patients will be recruited into the trial for a duration of 6 hours after which their will be no further intervention. The ICNARC data show that there are approximate 700 patients per year requiring mechanical ventilation. According to the current unit workload and staffing level, we aim to recruit 6-8 patients with the inclusion criteria per month. It is estimated that it will take about 6 months to 1 year to complete the project.
