High svo2 - Study guides, Class notes & Summaries

SVO2 Normal - >60% Low SVO2 - Inadequate oxygen delivery or increased oxygen consumption Ex: fever, pain, bleeding, infection High SVO2 - increase in CO, decrease in oxygen demand, reduction in oxygen extraction Ex: anesthesia, hypothermia CVP Normal - 2-6 High CVP - over hydration, cardiac tamponade, heart failure, pulmonary stenosis. Patient needs diuresis, vasodilation, or treatment for tamponade. Low CVP - hypovolemic shock for hemorrhage, fluid shift, dehydration. Pati...

What is the most important sign in a critically ill pt? Why? - ANSWER-Tachypnea Indicates metabolic acidosis w/ respiratory alkalosis compensation A pt misses dialysis for a few days and comes in with fluid overload. He's tachycardic and tachypneic. On physical exam, you find JVD, pulsus paradoxus (20 mmHg drop during inspiration), and HoTN (80/40) with distant, muffled heart sounds. Lungs are clear to auscultation. What is the dx? - ANSWER-Cardiac tamponade; obstructive shock If a pt ...

IV/VI murmurs - are loud when heard through a stethoscope and are accompanied by a palpable thrill (i.e., palpable vibration) sentinel event - unexpected occurrence involving death, serious or permanent physical or psychological harm, or the risk thereof; applies if no harm occurs, but the same circumstances could result in harm in the future. mitral regurgitation - S3 with a systolic, high-pitched murmur at the fifth intercostal space. s/s: fatigue, trouble breathing while exertin...

ABG FINAL EXAM SOLVED COMPLETE QUESTIONS AND CORRECT DETAILED ANSWERS (VERIFIED ANSWERS) 1. What does the steep part of the oxy Hb curve represent? - ANSWER between 10 and 60mmHg- this is where O2 will rapidly bind with Hb 2. What factors affect the oxy Hb diss. Curve? - ANSWER changes with temp, CO2, 23DPG and PH. 3. A decreased affinity means? - ANSWER A left shift- temp, 23 dpg or CO2 decreases, this leads to an increase in PH 4. How does a decrease or increase in...
