Which of the following is an acceptable description of diastolic pressure?

Group of answer choices

It is the same as the cardiac output

None of the listed options is a description of diastolic pressure

The pressure in a blood pressure cuff at which the first heartbeat sound is heard through a stethoscope as the pressure in the cuff is slowly relieved

The pressure in a blood pressure cuff just before pressure in the cuff is relieved

The pressure in a blood pressure cuff at which the last heartbeat sound is heard through a stethoscope as the pressure in the cuff is slowly relieved

OUTPUTS ARE VOLUMES OF BLOOD IN CARDIAC SYSTEM WHILE CARDIAC PRESSURE IS DIFFERENT.

THE PRESSURE OF THE CUFF IS MADE TO HIGH EVEN MORE THAN SYSTOLIC PRESSURE AND NO SOUND IS STETHOSCOPE IS HEARD. AS THE PRESSURE IS RELEASED SLOWLY FIRST SOUND CORRESPONDS TO SYSTOLIC PRESSURE WHICH IS DUE TO BURST OF BLOOD THROUGH ARTERIES AS SOON AS PRESSURE IN CUFF IS LOWER THAN THE SYSTOLIC PRESSURE. THEN RELEASE OF PRESSURE SLOWLY LEADS TO LISTENING OF HEART BEAT AS MIX OF DIASTOLIC AND SYSTOLIC PRESSURE. LAST SOUND IS OBSERVED WHEN CUFF PRESSURE REACHES THE DIASTOLIC PRESSURE AFTER THAT NO SOUND IS OBSERVED IN STETHOSCOPE.

SO LAST OPTION IS CORRECT
