Low quality stethoscope. quality stethoscopes do not transmit sound well enough to accurately hear blood pressure sounds. Select a blood pressure cuff of a suitable size. - Page 48 Use the correct Korotkoff sound to determine diastolic blood pres- sure. • Many listeners incorrectly equate diastolic blood pressure with the disappearance of sound only (phase 5). The Welch Allyn Spot Vital Signs was developed using the American Heart Association recommendations, which state that phase 5 be used unless sound continues to 0 mmHg, in which case the change in the quality of sound (phase 4) is to be used.
