^*If GMH-IVH is detected at any time, until the hemorrhage and the PHVD are stabilized, cUS scans should be continued at least once a week for low-grade hemorrhages (Grade I and Grade II) and at least twice a week for high-grade hemorrhages (Grade III and PVHI).

^**cUS should be repeated in infants with a new-onset hemodynamic impairment, sepsis, meningitis, severe respiratory disorders, and heart failure.

^***cUS scan should be performed in case of any risk factor or conditions which may cause hemodynamic impairment such as sepsis, meningitis, severe respiratory disorders, or congestive heart failure in the preterm group above >32^0/7 weeks.
