The technique is designed to improve preoxygenation by providing controlled sedation.1 The current evidence consists of data from small studies of patients sedated with ketamine and successfully preoxygenated and intubated.1-6 DSI evidence is based on a small series of cases. This technique can be successful for many patients, including those with asthma.
