Hi,
I really wonder if someone can survive with 400 blood pressure. Conventional BP apparatus shows a maximum of 300. So there is something wrong with the measurement.
However, sudden spike of BP may be due to conditions like pheochroma , renal arterial stenosis etc..
Consult a physician urgently and get him evaluated.
All the best.
