Even though heart rate is increased, the amount of blood that the heart can pump per beat is reduced because of overall low blood volume. For example, during dehydration your heart rate might be 90 beats a minute, but your heart might be pumping only 40 … ryan crumplerWitrynaIn an effort to preserve oxygen delivery, a greater volume of blood is circulated, that is, cardiac output is increased. However, this pattern of compensation is only temporary. Within days, hemoconcentration increases the oxygen-carrying capacity of the blood, and as a consequence, less cardiac output is required to maintain oxygen delivery. is dr lynette nusbacher a man or woman
