Respiratory Support and Acute Respiratory Distress Syndrome (ARDs) Expectations This is not a respiratory therapy program We are not pulmonologists or anesthesiologists The goal is to achieve a basic understanding of the principles of respiratory support Passive Oxygen Delivery Nasal Cannula Passive Oxygen Delivery Simple Oxygen mask Passive Oxygen Delivery Non-Rebreather Mask Positive Pressure – Non-Invasive CPAP Pressure Time Obstructive Sleep Apnea (OSA) Positive Pressure – Non-Invasive BiPAP Pressure Time Bag Valve Mask Nasal-Pharyngeal and Oro-Pharyngeal Airways Tracheal Intubation Invasive Mechanical Ventilation Pressure Control Vs Volume Control Synchronized Intermittent Mandatory Ventilation vs Assist Control Acute Respiratory Distress Syndrome What is it? “An acute diffuse, inflammatory lung injury, leading to increased pulmonary vascular permeability, increased lung weight, and loss of aerated lung tissue with hypoxemia and bilateral radiographic opacities, associated with increased venous admixture, increased physiological dead space, and decreased lung compliance” Berlin Classification of ARDS Timing Chest imaging Origin of Edema Within 1 week of a known clinical insult or new or worsening respiratory symptoms Bilateral opacities – not fully explained by effusions, lobar/lung collapse, or nodules Respiratory failure not fully explained by cardiac failure or fluid overload Oxygenation with PEEP > 5 cm H20 Mild PaO2/FiO2 between 200-300 mmHg Moderate PaO2/FiO2 between 100-200 mmHg Severe PaO2/FiO2 between
