[{"arm_notes": "", "treatment_id": null, "treatment_name": "Patients enrolled in the intervention arm will be asked to lie prone according to an \"intervention plan\". In short; they will be enrolled with the aim of lying prone for up to 12 hours a day in a prone position. This time does not have to be continuous and it will be suggested that it is broken into smaller time periods; tailored to each patients level of comfort. There is no minimum time been period of pruning and no restriction on participants positioning outside of the 'intervention' periods. If this duration is not tolerated for an individual patient; staff will trial a variety of comfort measures - for example; adding pillow padding under thighs and shoulders; adjusting each patients prone position modified swimmers position and then if required follow a planned \u2018de-escalation\u2019 protocol; to find the maximum tolerable proning time for each patient. The intervention will continue for 72 hours (a maximum of 36 hours prone).If a participant is unable to tolerate a 12h/day prone position as above; this can be reduced. A comfortable \u2018proning limit\u2019 for each patient can be found and then this can continue for the remaining trial period. Step 1 - Trial 3 x 3hr sessions/9 hours a day Step 2 - If needing longer breaks not prone - Trial 2 x 4hr sessions/8 hours a dayStep 3 - Trial 2 x 3hr sessions/6 hours a day Step 4 - 3 x 2 hour sessions/6 hours a day Step 5 - 2 x 2 hours sessions/4 hours a day Step 6 - Abandon proning; document in EMR why proning was abandoned", "treatment_type": "TODO", "pharmacological_treatment": "TODO"}]
