Peer reviewed by Maurice Le Guen OVERVIEW Delirium is a disturbance of consciousness with inattention accompanied by a change in cognition or perceptual disturbance that develops over a short period of time and fluctuates over time (DSM4) inattention is one of…
Daily Interruptions of Sedation in Mechanically Ventilated Patients designed to reduce exposure to sedative agents; allow assessment of neurological status; assess readiness for extubation; and reduce duration of mechanical ventilation
OVERVIEW Acute Respiratory Distress Syndrome (ARDS) is 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…
definitions of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) have varied over time. ARDS was first described by Ashbaugh and Petty in 1967 in a case series of 12 ICU patients who shared the common features of unusually persistent tachypnea and hypoxemia accompanied by opacification on chest radiographs and poor lung compliance, despite different underlying causes
Airway pressure release ventilation (APRV) is inverse ratio, pressure controlled, intermittent mandatory ventilation with unrestricted spontaneous breathing
based on the Open Lung Approach To Ventilation first described by Stock et al 1987
OVERVIEW Pressure versus Time Graph. Information obtained peak inspiratory pressure plateau pressure compliance = gradient between PIP and Pplat (small = decreased) type of ventilation (volume vs pressure controlled) get a sense of flow rate CPAP level = pressure at…
Flow Volume Loops. provide a graphical analysis of inspiratory and expiratory flow from various inspired lung volumes. Breathing across a pneumotachograph subjects inhale to TLC -> FEC manoeuvre -> rapidly inhale back to TLC.
