Ans. is ‘c’ i.e., Absent end diastolic flow
- The pulsed wave Doppler obtained can demonstrate the presence of ductal steal by assessing the diastolic flow in the vessel.
- Panel (A) demonstrates normal flow.
- Panel (B) demonstrated absent end diastolic flow in moderate PDA steal and
- Panel (C) demonstrates revered diastolic flow in severe PDA steal.
