Question

Определи сколько секунд потребуется сердцу чтобы перекачать 3 л крови

Answer 1

1.Измеряешь артериальное давление(АД)
2.от большого отнять меньшее,получишь ударный объем сердца(УО)
3.Измеряешь пульс-частоту сердечных сокращений (ЧСС в минуту)
4.УО умножить на ЧСС-количество крови, перекачиваемое за минуту.
Пример:АД 110 на 70. 110-70=40.ЧСС=65 УДАРОВ в минуту.
65*40=2600мл/мин.
В состоянии покоя 30 секунд.

Answer 2

Calculating Time for Blood Circulation

To calculate the time required for the heart to pump 3 liters of blood, we can use the average cardiac output and the total volume of blood to be circulated.

Average Cardiac Output: The average cardiac output for an adult at rest is approximately 5 liters per minute.

Volume of Blood: The total volume of blood to be circulated is 3 liters.

Calculation

Using the average cardiac output, we can calculate the time required for the heart to pump 3 liters of blood:

1. Time (in minutes) = Volume of Blood / Cardiac Output - Time (in minutes) = 3 liters / 5 liters per minute - Time (in minutes) = 0.6 minutes

To convert the time from minutes to seconds: 2. Time (in seconds) = Time (in minutes) * 60 - Time (in seconds) = 0.6 minutes * 60 - Time (in seconds) = 36 seconds

Therefore, the heart would require approximately 36 seconds to pump 3 liters of blood.

This calculation is based on the average cardiac output and the given volume of blood to be circulated.
