Question

How can a low fetal heart rate be increased on cpb?

1) By administering medication
2) By adjusting the oxygen flow rate
3) By increasing the blood flow through the heart-lung machine
4) By performing a surgical procedure

Answer 1

To increase a low fetal heart rate on CPB, medication, adjusting oxygen flow rate, and increasing blood flow through the heart-lung machine can be used.

Step-by-step explanation:

Fetal distress, measured as a sustained decrease or increase in the fetal heart rate, can result from severe contractions that are too powerful for oxygenated blood to be restored to the fetus. To increase a low fetal heart rate on CPB (Cardiopulmonary Bypass), several methods can be used.

1. By administering medication: Medications can be given to increase the heart rate in case of low fetal heart rate.
2. By adjusting the oxygen flow rate: Increasing the oxygen flow rate can help provide adequate oxygen to the fetus, which can potentially increase the heart rate.
3. By increasing the blood flow through the heart-lung machine: By increasing the blood flow through the heart-lung machine, more oxygenated blood can be delivered to the fetus, which can help increase the heart rate.
