Outcomes
Primary outcome [1] 2532 0
Proportion of patients with an increase in partial pressure of arterial carbon dioxide (PaCO2) greater than or equal to 4mmHg
Timepoint [1] 2532 0
At 1 hour
Secondary outcome [1] 4374 0
Proportion of patients with a partial pressure of arterial carbon dioxide (PaCO2) greater than or equal to 38mmHg and an increase of greater than or equal to 4mmHg.
Timepoint [1] 4374 0
At 1 hour
Secondary outcome [2] 4375 0
Change in respiratory rate and heart rate at time 0, 20minutes, 40minutes and 1hour.
Timepoint [2] 4375 0
At time 0, 20minutes, 40minutes and 1hour
Secondary outcome [3] 4376 0
Need for hospital admission at the end of the emergency department treatment period. The end of the emergency department treatment is variable as it depends on the patient and the severity of the condition, and therefore a time can not be specified.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects that consent and meet the study criteria will be enrolled onto the study and allocated treatment from a secure randomisation list held on computer database and accessed by log-in code
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Third party randomisation will be used with random number sequences generated by a computer programme
Masking / blinding
Open (masking not used)

Summary
Brief summary
Current standard treatment is to provide high flow oxygen to people with pneumonia. However high flow oxygen may be detrimental and few studies have looked at the use of high flow oxygen in pneumonia. An alternaitve treatment is one where the amount of oxygen received is varied depending on the oxygen level in the blood. This study compares the two treatments.
