HSV Encephalitis
HSV Encephalitis: severe viral infection of the central nervous system, caused by a herpes simplex virus and usually localised to the temporal and frontal lobe; most commonly identified cause of infectious encephalitis; 5-10% of encephalitis cases worldwide
Hypoxic Brain Injury
Hypoxic Brain Injury: in adults, typically occurs after cardiac arrest, trauma or drug overdose; degree of injury proportional to duration and severity of oxygen deprivation to the brain
Myasthenia Gravis
Myasthenia Gravis: autoimmune disruption of post-synaptic acetylcholine receptors at NMJ; up to 80% of functional receptors loss; typically young woman; may have thymus hyperplasia; prevalence = 14.2 cases per 100,000

Non-Convulsive Status Epilepticus (NCSE)
Non-Convulsive Status Epilepticus (NCSE) is a persistent change in the level of consciousness, behaviour, autonomic function, and sensorium from baseline associated with continuous epileptiform EEG changes, but without major motor signs
Airway exchange catheter
Airway exchange catheter; aka airway exchange guide; examples include the Cook Airway Exchange Catheter and the Aintree Intubation Catheter
A-a gradient
A-a gradient is calculated as PAO2 – PaO2. A normal A–a gradient for a young adult non-smoker breathing air, is between 5–10 mmHg.
Intubation and Mechanical Ventilation
INDICATIONS A – protection and patencyB – respiratory failure (hypercapnic or hypoxic), increase FRC, decrease WOB, secretion management/ pulmonary toilet, to facilitate bronchoscopyC – minimise oxygen consumption and optimize oxygen delivery (e.g. sepsis)D – unresponsive to pain, terminate seizure, prevent…
