Welcome back, this is our last podcast before our short summer break! We start off having a look at the physiological effects of prolonged resuscitation with a supraglottic device compared with endotracheal intubation, which raises some really interesting questions about our ongoing ventilation strategy in resuscitations. Next up we look at an RCT comparing RSI to DSI in critically injured patients and the effect on peri-intubation hypoxia. Finally we take a look at the practice of lateral canthotomy for retrobulbar haemorrhage/orbital compartment syndrome. How effective is the procedure and how competent are EM clinicians compared to Opthalmogists? Once again we’d love to hear any thoughts or feedback either on the website or via twitter @TheResusRoom and we'll see you back in September! Simon & Rob
