Final answer:
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.
- By administering medication: Medications can be given to increase the heart rate in case of low fetal heart rate.
- 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.
- 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.
