AMOUNT OF BLOOD EJECTED BY EACH VENTRICLE IN ONE MINUTE IS THE CARDIAC OUTPUT (CO) ปริมาณเลือดที่ออกจากหัวใจใน 1 นาที CO stroke volume x HR HEART RATE IS HOW MANY BEATS PER MINUTE (BEATS/MIN) STROKE VOLUME VOLUME OF BLOOD PUMPED BY EACH VENTRICLE WITH EACH HEART BEAT (ML/BEAT) เลือดที่ออกจากหัวใจ ในปีมครั้งนึง
ページ2:
HEART RATE IS HOW MANY BEATS PER MINUTE (BEATS/MIN) AMOUNT OF BLOOD EJECTED BY GACH VENTRICLE IN ONE MINUTE IS THE CARDIAC OUTPUT (CO) CO SV & HR = (ML/BEAT) (BEATS/MIN) = 70ML/BEAT * 75 BEATS/MIN CO: 5250mL/MIN (~SL/MIN) STROKE VOLUME VOLUME OF BLOOD PUMPED BY EACH VENTRICLE WITH EACH HEART BEAT (ML/BEAT)
