Clinical Question

Reviews preoxygenation and peri-intubation oxygenation techniques to minimize the risk of critical hypoxia and introduces a risk-stratification approach to emergency tracheal intubation.

Design

Review of methods and approaches to preparing for intubation of patients with varying levels of risk of hypoxia.

{What do they recommend while awaiting the onset of muscle relaxation for a patient who is hypoxemic (<90% SpO2)? |type="[]"} -NRB and nasal oxygen at 15L/min -NRB, CPAP or BVM with peep and nasal oxygen at 15L/min +CPAP or BVM with peep and nasal oxygen at 15L/min

{What is the recommendation for passive oxygenation in low risk (>96% or above SpO2) intubation patients? |type="[]"} -It is always indicated +It may not be necessary but could extend safe apnea in the event of repeated intubation attempts. -It could increase the risk of adverse events due to complications from equipment confusion
