Med-Surg Sp2017 ARDS & Mechanical Ventilation Unresponsive arterial hypoxemia Explanation: Acute respiratory distress syndrome (ARDS) can be thought of as a spectrum of disease, from its milder form (acute lung injury) to its most severe form of fulminate, life-threatening ARDS. This clinical syndrome is characterized by a severe inflammatory process causing diffuse alveolar damage that results in sudden and progressive pulmonary edema, increasing bilateral infiltrates on chest x-ray, hy...

Core Concepts Exam 3 Inadequate oxygen in the blood hypoxemia Inadequate tissue oxygenation hypoxia ___ are invasive & the most accurate direct measure of oxygen and carbon dioxide exchange and the acid-base balances in the blood arterial blood gasses Normal pH level 7.35-7.45 PaO2 level 75-100 PaCO2 level 35-45 HCO3 level 24-28 Noninvasive measure of oxygen saturation of the blood pulse oxometry The complete act of oxygenating the body; breathing...

ABG Interpretation Questions and Answers 100% Pass Which blood gas measurement assesses the efficiency of a patient's lung ventilation? PaCO2 Which blood gas measurement gauges the extent of tissue oxygenation? PvO2: Typically ranges between 35 - 45 mmHg. A decreased PvO2 indicates insufficient oxygenation of tissues, often due to reduced cardiac output. When cardiac output declines, blood flow to tissues slows, while tissue oxygen uptake remains unchanged. Consequently, some tissue...

FCCS Exam Questions with All Correct Answers What is the most important sign in a critically ill pt? Why? - ANSWER Tachypnea Indicates metabolic acidosis (often 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...

Reasons for Mechanical Ventilation - ANSWER: - Acute Respiratory Failure - Ventilatory Failure - not moving adequately but perfusing - Oxygenation Failure - moving air but perfusing inadequate - Combined Ventilatory and Oxygenation Failure Acute Respiratory Failure - ANSWER: - Classified as blood gas abnormality - PaO2 less than 60 mm Hg (however, less than 80 is hypoxemia) - PCo2 greater than 45 mm Hg with acidosis. - Sa02 less than 90%. (pulse oximetry) - Can be caused by ventilat...

Lewis Chapter 67: Acute Respiratory Failure and ARDS NCLEXThe nurse is caring for a 27-yr-old man with multiple fractured ribs from a motor vehicle crash. Which clinical manifestation, if experienced by the patient, is an early indication that the patient is developing respiratory failure? A Tachycardia and pursed lip breathing B Kussmaul respirations and hypotension C Frequent position changes and agitation D Cyanosis and increased capillary refill time - correct answer C Frequent po...
