RK.MD Perioperative And Critical Care Reference Sheet

Ever since finishing my fellowships, I wanted to create a free reference sheet (front and back) containing “high yield” information in the areas of critical care and perioperative medicine. I feel I’m well suited to pursue this educational endeavor given my training as a physician who works in both settings, and hopefully, many of you will benefit from the information. Now some details:

  • This sheet doesn’t constitute medical advice, and I’m NOT responsible for any decisions or outcomes.
  • Share this document freely, but I ask that you give me credit for it (hence the watermark).
  • I used a combination of Pixelmator Pro and Microsoft Excel to construct the document. I used GoodNotes on my iPad Pro to draw the diagrams.
  • Many areas are up for debate (ie, medication doses). Remember that these are largely based on my practice as a cardiothoracic anesthesiologist and intensivist. Your institution’s policies and practices may differ considerably.
  • If you print this out, you might need to scale the document to fit on a single page or adjust your printable margins to 0. Use print preview to make sure everything is in view!
  • If you have any suggestions or want to report errata, contact me! Drop me a comment below and buy me a coffee if you find this reference sheet helpful! 😀

  1. Thanks Doc! I’m an ICU nurse but also a nursing instructor for students on their ICU rotation. They do 4 weeks with me in CVICU and I’m so pumped to share this with them. I greatly appreciate everything you do, and all the knowledge you share with all of us across all specialties and disciplines of healthcare.

  2. Thank you for this! A quick glance to better understand things in my busy ICU is super appreciated. The resources you provide are amazing and unbelievably valuable. Thank you for sharing your knowledge 🙂

  3. Your content for my field as a flight nurse is so spot on; easy to digest and refresh. Thank you for helping me help others better.

  4. For the amount of great contributions you are doing, you should be rewarded or something!! These are amazing! Everytime I come across your page I can’t help but feel inspired to do better and feel motivated. People like you are very rare!

  5. Emergency RN here. These are amazing! Better than anything I’ve ever paid for! Thanks, Rishi. Excellent videos also! What can I send you?

    • Haha, thanks so much for the compliment, Ryan! No need to send me anything – these are made freely available for the sole purpose of educating. Glad you found it helpful! Stay tuned for my follow-up reference sheet on mechanical circulatory support devices! 🙂

  6. This is fantastic, man! Top shelf material. As a CA0 Anesthesia intern in the CVICU right now, picking up all this stuff in bits, from PA caths and what CVP values I “should believe”, to vasoactive dosing, the prospect of ALL this info in one place, is kind of an amazing gift. I’m gna have to keep a closer eye on this blog haha. Also planning to come your way in a few months to ask about what I should be thinking about, aiming at, if I think–as I presently do–I may want to do a CC/Cardiac fellowship double-dip.

    • Thanks so much for the kind words! Haha, oh yeah, feel free to drop me questions anytime! Best wishes to you as you wrap up intern year. Stay safe and motivated!

  7. Thank you Rishi for putting this together. In times where more of us without formal ICU training are getting deployed to take care of critical care patients this is extremely helpful. Much appreciated!

  8. Incredible reference! I am in graduate school and I have found all of your insta posts and this reference sheet amazing. I am hoping that you one day publish an ICU book. I’ve even got a title for you! “The Rishi Reference”!

    • Hahaha, I really appreciate the comment, Nikki! I don’t really think I’ll ever publish a book in the conventional sense – I rather keep everything available on the Internet (ie, this website) for anyone to read anywhere at anytime for free. 🙂

  9. Thanks Rishi, Excellent document for reference. Accurate and detailed.

    • Thank you! It was difficult to decide what to include on the sheet and arrange things so they look semi-organized, but I’m appreciating all the positive feedback!

  10. Haven’t had a chance to look at it in too much detail but it looks great! Excited to keep a copy in my scrub pocket 🙂 Thanks again!!

  11. Hi… i am a doctor in South Africa just starting my studies in anaesthesia and critical care. I have been following you on insta for some time now and have been learning alot. The reference sheet is really great. Im going to make sure its on the wall of our theatre.

    Thank you and keep up the great work

    • Thanks so much for the kind words, Muhammed! Both my anesthesiology residency and cardiothoracic anesthesia fellowship program directors are from South Africa. They always spoke so fondly of their home. Hope to visit someday!
