Outcome Measures

Primary Outcomes (1)

  • MCA PI change before and after maternal hyperoxygenation

    The response of the MCA PI to maternal hyperoxygenation in various forms of CHD. MCA PI at MH will be compared to baseline at various gestational ages in a variety of types of CHD.

    10-15 minutes

Secondary Outcomes (1)

  • UA PI change before and after maternal hyperoxygenation

    10-15 minutes

Other Outcomes (3)

  • Response of myocardial diastolic function to MH in various forms of CHD

    10-15 minutes

  • Systolic function change before and after MH

    10-15 minutes

  • Changes in flow pattern at the aortic isthmus

    10-15 minutes

Study Arms (1)

Maternal Hyperoxygenation

OTHER

Maternal hyperoxygenation will be offered by administering 10 liters nasal cannula by face-mask (approximately 60% fiO2) for a minimum of 10 minutes.

Biological: Maternal hyperoxygenation

Interventions

approximately 10-15 minutes of maternal hyperoxygenation

Maternal Hyperoxygenation

Eligibility Criteria

Sexfemale
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • All singleton fetuses with CHD at all gestational ages are eligible for enrollment in the study. Patients will be recruited to enroll in the study as they present for clinical care at Fetal Echocardiography clinic. MH assessments will all be performed only at the Beijing Anzhen Hospital. Baseline room air data for CHD may be collected from other referring centers within the Anzhen network.

You may not qualify if:

  • Non-sinus rhythm, presence of arrhythmia; Fetal hydrops; Severe brain anomaly (which may influence MCA flow); Evidence for significant ventricular dysfunction; Evidence for constriction of the ductus arteriosus
