The ICU is a field of knowledge. It grows theories and ideas that hovers on all of your senses. The beeping cardiac monitor wakes you up and speaks to you among its eerie lines. The sound of your patient’s breathing alerts you to start moving. The look and feel of your patient’s skin spells out the pages you’ve brood over in college. The smell of burnt air also gives you its own dire signs. Imagine these raking your senses all at the same time.
