decreased blood oxygen measured by low arterial O2; low hemoglobin saturation hypoxemia decreased in tissue oxygenation hypoxia Hypercapnia ventilatory failure inadequate alveolar ventilation in relation to production of carbon dioxide, decrease respiratory rate, hypovolemia, increase dead space What happens inside the alveoli for ARD? water, cell, and protein leaks into the tissue around the alveoli and cause large areas of alveoli to collapse What are the causes of Acute Respiratory ...

Define ARDS. - ️️Acute respiratory distress syndrome - inflammatory response leading to diffuse alveolar damage and lung capillary endothelial injury. What is the evidence for use of omega-3 fatty acids in ARDS and ALI? - ️️Based on 3 level 1 studies the Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Adult Critically Ill Patient in 2009 recommended patients with ARDS and severe ALI be placed on an enteral formulation characterized by an anti-inflamma...

Comprehensive CRNA Interview Review Accurate responses are given. Comprehensive CRNA Interview Review Norepinephrine Mechanism of Action (MOA) A1, A2, B1 agonist. Primary agent used in distributive shock because it's ability to recruit venous volume and augment preload, while increasing arterial tone, and increasing cardiac output. Alpha one causing peripheral smooth muscle contraction. (low dose venous, high dose venous and arterial). Alpha 2 adrenoreceptor agonism actually ant...

A 60-year-old man with a history of multiple myocardial infarcts is hospitalized for shortness of breath. Physical examination reveals marked jugular distension, hepatomegaly, ascites, and pitting edema. A chest X-ray reveals cardiomegaly. The patient subsequently dies of cardiorespiratory failure. Examination of the lungs at autopsy would most likely disclose which of the following pathologic changes? (A) Diffuse alveolar damage with hyaline membranes (B) Intra-alveolar purulent exudate (C) ...
