Specifically, this formula approximates the amount of oxygen used by the heart. This formula is also called the pulse pressure product. The MVO2 value is easy to calculate. You simply multiply the heart rate and systolic blood pressure, the resulting number is the MVO2 value.
Myocardial Oxygen Consumption (MVO2) Calculator
This myocardial oxygen consumption (MVO2) calculator determines the quantity of oxygen used by cardiac function based on coronary flow and arteriovenous oxygen difference.
混合静脉血氧饱和度(MvO2) - 好大夫在线
MVO2表示返回到心脏未使用的氧气的量,修改的Fick原理。 MvO2= SaO2 −V˙ O2/ (CO × 13.9 × Hg) lMvO2,或O2经过全身灌注后在静脉血内的剩余,可以作为氧气供应(氧饱和度,血红蛋白,心输出量),氧的需求(组织/细胞的代谢需求)和组织氧合(氧气输送对需求的有效性)的一个指标。 l在正常条件下,休息状态,MvO2= 75%(40毫米汞柱,PaO2)。 氧气供应量>氧气需求量。 只有25%的氧气利用或从血液中提取,遗留安全储备量75%。 l火车站比喻:氧气(货 …
Physiology, Myocardial Oxygen Demand - StatPearls - NCBI Bookshelf
2023年7月4日 · Myocardial oxygen demand is the amount of oxygen that the heart requires to maintain optimal function, and myocardial oxygen supply is the amount of oxygen provided to the heart by the blood which is controlled by the coronary arteries.
CV Physiology | Determinants of Myocardial Oxygen Consumption
Myocyte contraction is the primary factor determining myocardial oxygen consumption (MVO 2) above basal levels. Therefore, factors that enhance tension development by the cardiac muscle cells, the rate of tension development, or the number of tension generating cycles per unit time will increase MVO 2.
Estimating Myocardial Oxygen Consumption Using a Pulmonary …
We hypothesize that Delta SO2 bears a direct relationship to coronary sinus blood O2 saturation and by extension, to myocardial O2 consumption (MVO2). METHODS: An equation was developed using a two-compartment mass transport model relating MVO2 to DeltaSO2.
[Oxygen requirements of the myocardium] - PubMed
Myocardial oxygen consumption (MVO2) is defined by the equation: MVO2 = coronary blood flow x arteriovenous difference in O2 content. The average value for a heart of 300 g is 30 to 35 ml/min. In the absence of physiological variations in the arteriovenous difference in O2 content, MVO2 is related t …
CENTRAL VENOUS/MIXED VENOUS OXYGEN SATURATION
Mixed venous oxygen saturation (SvO2) can help to determine whether the cardiac output and oxygen delivery is high enough to meet a patient's needs. It can be very useful if measured before and after changes are made to cardiac medications or mechanical ventilation, particularly in unstable patients. What are the normal values? Normal SvO2 60-80%.

mvo2医学的意思 - 百度文库
mvo2,全称为混合静脉血氧含量,是衡量人体组织对氧的利用情况的重要指标。 它反映了人体组织在单位时间内从静脉血中摄取氧的量,也就是说,mvo2的大小直接反映了人体组织对氧的需求量。
