The ICU Core Lecture Series, running from Monday to Thursday, is delivered by the ICU fellow or the attending to interns and residents currently on rotation. This lecture series encompasses a range of crucial topics imperative for internists practicing in the ICU setting, including Mechanical Ventilation, Renal Failure, Nutrition for critically ill patients, and Bleeding Complications in the ICU. Additionally, once a week, a simulation-based lecture is conducted at the simulation center, incorporating simulated patient scenarios or procedural skills. This lecture delivery forms an integral part of the training regimen for ICU fellows, helping them reinforce their knowledge and enhance their teaching skills. Both the ICU fellow and the staff should plan in advance which lectures each will deliver to provide the fellows with adequate preparation time for their lectures.
