Dr. Daniel Saddawi-Konefka
- A previously healthy 27-year-old woman was scheduled for elective cholecystectomy. Examination of her airway demonstrated a modified Mallampati score of 2; however, she was unable to bite her upper lip with her lower incisors. What will be your approach to her airway?
- You are called for rapid airway response to a 68-year-old woman with pneumonia on the medical ward. She has worsening hypoxemia and the need for mechanical ventilation. On initial inspection she was obese, breathing at a respiratory rate of 40 breaths per minute, and had retrognathia. Oxygen saturation is 92% on 10 L/min. She is tachycardic with a stable blood pressure. he is confused and uncooperative. Her compromised clinical condition precluded a thorough oropharyngeal and neck examination. What will be your approach to her airway?
- You are called to the Emergency Room to evaluation a 50-year-old man with tongue swelling after taking an ACE inhibitor. On examination, his tongue is firm and protruding from his mouth. His teeth have cut into his tongue a little bit causing a small amount of bleeding. There is no room between his teeth and tongue. His condition has worsened over the 30-60 minutes. He is still on room air but having increasing difficulty handling his secretions. He is extremely anxious, sitting completely upright, hypertensive and tachycardic.

- You take over care of a 71M with bacteremia and from urosepsis and ARDS, who is having ureteral stents placed. His blood pressure reads 132/68, and he is on norepinephrine and vasopressin. List at least 5 ways more is fine) that, despite a “normal” blood pressure, he may have inadequate tissue perfusion. What could you do to determine whether these are in play?
- How would CVP be affected by non-venous-hemodynamic factors: Obesity? Ventilation pressures? Tricuspid regurgitation? Third degree heart block? Etc?
