<prompt> Blood pressure measured using a sphygmomanometerMay be falsely low with too narrow cuffMay be falsely low in patients with badly stiffened aeriesMay be falsely high in obese patientsGives a direct reading of mean aerial pressure  <response>: If the cuff is too small, it takes a falsely high pressure in the cuff to transmit sufficient pressure to the vessel wall for total occlusion of the aery.Blood pressure may be falsely high in patients with badly stiffened aeries because of the extra pressure needed to compress the aeries.
