What classes as stage 2 hypertension
150/95 - treat.
signs of quinine overdose
visual disturbances, tinnitus flushing
hypoglycaemia and metabolic acidosis
can get flash pulmonary odema
MArkers of poor prognosis in IgA nephropathy
hypertension proteinuria male gender smoker (frank blood is a good prognostic)
differnce between an IgA nephropathy and a post streptoccal glomerulonephritis
IGA frank blood and more often men, comes on after 1-2 day sof URTI
PSG - comes on afetr 2 weeks and just protein

indications for bipap
copd with respiratory acidosis
type 2 resp failure secondary to OSA/chest wall deformity/neuromuscular disease
withdrawal of intubation
cardiogenic pulmonary odea - non responsive to cpap
recomended inspiratory and end pressurees in copd - bipap

give fluids for 12 hours before and after 1ml/kg/hr
Hypersensitivity types: gell and coombes
type 1 - anapjylactic (IgE mediated)
type 2 - cell bound - binds to antigen on cell surace
type 3 - imune complex - free antigen antibody e.g SLE/ post strep glom
type 4 - t cell meicated - eg TB, GVHD, scabies, MS, GBS
