Why have BP techniques shown limitations so far?

Customary units in human as well as in veterinary medicine offer:

• Linearity of the deflation rate of the valve only in the area of 160 to 80 mmHg.
• that means that any higher and lower pressures cannot be detected accurately.

These are the speed limitations of conventional 8-bit devices

• The use of 8 bit processors imposed limits on signal identification and analysis
• The measureable pressure maximum was at 250mmHg
• No realtime measurement, thus no valve programming possible
• Pulse identification limited to pulses up to 160 – 200 bpm

Recent new developments in human and veterinary medicine

• Human medicine: a 16 bit processor driven unit was announced at MEDICA 2005 to be launched in 2006
• Veterinary Medicine: Memodiagnostic*
  High Definition Oscillometry (HDO) based on 32 bit processors (*will be launched during BSAVA through VetDirect in 2006)
