What is type I hypersensitivity (anaphylaxis)?

I'm joined today by a special guest Justin and we go through an overlooked topic of 'Immunology & Hypersensitivity.' The first learning objective is to review how the body defends against infection (05:46) and then look how this is effects under anaesthesia (14:06). Finally, we have a long conversation about the pathophysiology of hypersensitivity (16:22) and the clinical context of the treatment of anaphylaxis (24:18). I want to thank Justin again for joining me today and as always if you have any feedback let me know.
