Sidney Weinstein
Sidney Weinstein (1922 - 2010) was and American neuroscientist and neuropsychologist. Semmes-Weinstein monofilament test and the Weinstein Enhanced Sensory Test
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.
Volutrauma
Volutrauma = complication from mechanical ventilation that may manifest as: extra-alveolar air and/or acute ventilator induced lung injury.
High Frequency Ventilation
High Frequency Ventilation ventilation with small tidal volumes at high frequencies

Persistent and Chronic Critical Illness
Advances in intensive care have led to a growing cohort of patients of patients, who would have otherwise succumbed to acute illness, survive in a state dependent on prolonged intensive care therapies including mechanical ventilation
Haematuria in trauma
Haematuria in trauma may be microscopic (with or without symptoms) or macroscopic. In general, the greater the degree of hematuria the greater the risk of significant intra-abdominal injury (including non-urinary tract structures)
Increased Intracranial Pressure in TBI
Increased Intracranial Pressure in TBI; normal ICP 7-15mmHg
sustained increases > 20mmHg is associated with ischaemic brain injury
Codman ICP Monitor
Codman ICP Monitor: intracranial pressure monitor (aka 'BOLT')
Extradural ICP monitors
Extradural ICP monitor: ICP monitoring; catheter inserted though a burr hole but does not penetrate the dura
Traumatic Brain Injury (TBI) Assessment
OVERVIEW TBI assessment involves: HISTORY General (AMPLE) Specifically: EXAMINATION Specifically in TBI assess: Evidence of base of skull fracture: Look for evidence of trans-tentorial herniation: Look for evidence of underlying causes and complications INVESTIGATIONS Bedside Laboratory Imaging References and Links
