Delirium in ICU

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…

Interruptions of Sedation

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

High airway and alveolar pressures

High airway pressures are important because they may have adverse effects on the patient; indicate a deterioration of the patient’s condition; indicate an equipment problem that needs to be addressed

Acute Respiratory Distress Syndrome – ARDS

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…

Protective Lung Ventilation

Protective lung ventilation is the current standard of care for mechanical ventilation. It is synonymous with low tidal volume ventilation (4-8 mL/kg) and often includes permissive hypercapnia

Acute Respiratory Distress Syndrome Definitions

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)

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

Pressure versus Time Graph

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…

Volume versus Time Graph

Volume vs time graph: shape determined by flow pattern used in ventilation mode:-> ascending ramp: square wave; -> sinusoidal ramp: sine wave; -> exponential rise: decelerating flow pattern

Flow Volume Loops

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.
