Patent ID: 8439843

Claim:
A method of measuring ABPI and/or TBPI using at least two inflatable cuffs wherein: I. at least one of the cuffs is wrapped around an upper limb, II. at least one of the cuffs is wrapped around a lower limb, III. each of the cuffs has: A. an inflatable distal chamber situated closer to a free end of the limb whereupon the cuff is wrapped, and B. an inflatable proximal chamber situated closer to the trunk of a body from which the limb extends, the distal and proximal chambers being distanced along the limb; the method including the steps of: a. simultaneously inflating the distal chambers until the pressures measured therein provide Pneumo Arterial Plethysmography (PAPG) signals; b. while the distal chambers are inflated, simultaneously inflating the second proximal chambers until the PAPG signals are no longer detected; c. subsequently deflating the proximal chambers until PAPG signals are again detected in the distal chambers; d. subsequently deflating the distal chambers.
