Acute hypoxemic respiratory failure (AHRF) happens when the lungs are unable to absorb enough oxygen. The bloodstream is deprived of oxygen which can eventually lead to more severe conditions like multi-organ failure (MOF) and death. AHRF accounts for over 30% of patients to critical care units, thus novel treatments are sorely needed. Research has shown that blood levels of the inflammatory biomarker Interleukin-6 (IL-6) may be a reliable marker for predicting which patients with AHRF will progress into requiring intensive care unit (ICU) admission, MOF, and eventually death. IL-6 levels were shown to reliably peak several days before MOF, ICU admission, and death. Thus, the investigators believe that by identifying patients before the peak of their IL-6 levels, they will be able to administer early treatment to prevent the patient's condition from worsening. The aim of this study is to test the feasibility of a treatment strategy for AHRF based on IL-6 measurement in patients who are admitted to hospital care with AHRF. Patients who are eligible for the study will have their plasma IL-6 levels measured over 2 days. Patients with elevated IL-6 levels will be randomized into 1 of 3 treatment groups: standard of care only, standard of care plus a single IV infusion of Tocilizumab, or standard of care plus treatment with oral Dexamethasone for 10 days. Patients will then be observed till discharge or up to 28 days, and a follow-up phone interview will be conducted 6 months of the end of the observation period.

To determine the potential recruitment rate
Timeframe: From enrollment to completion of the study (in including the 6-month follow-up).
To assess the proportion of eligible patients who do not have daily IL-6 measurement
Timeframe: Baseline (Day 0) to Day 2
To assess the proportion of eligible patients who are not randomized
Timeframe: Baseline (Day 0) to Day 2
To determine the rate of adherence to the assigned treatment strategy and any cross-overs
Timeframe: Baseline to end of 28-day observation period (or hospital discharge)
To estimate the time from hospital admission to randomization and initiation of the allocated treatment
Timeframe: Baseline to Day 3
