IVC collabsibility index IVC distensibility index
Aim Volume status assessment in spontaneously breathing patientsVolume status assessment in mechanically ventilated patients
Method IVC images are acquired in the sagittal section.Images of the IVC draining into the right atrium are obtained while the probe is in the subxiphoid area and the liver is taken in the acoustic window.
Minimum IVC diameter on inspiration and maximum IVC diameter on expiration are measured.Maximum IVC diameter on inspiration and minimum IVC diameter on expiration are measured.
Formula (Maximum diameter on expiration – minimum diameter on inspiration)Maximum diameter on expirationMaximum diameter on inspiration – minimum diameter on expirationMinimum diameter on expiration
Benefits Quick, non-invasive, easy, repeatable, trustworthy and objective method for volume status evaluation17
Question marks There are no well-determined limits for the IVC collapsibility index and distensibility index in the pediatric age group in the published literature.Pediatric intensivists still use limitations described for adult patients for managing fluid therapy (for IVC collapsibility index >50%, for IVC distensibility index >18%).Further studies on large groups of critically ill pediatric patients could help to determine ultrasonographically measured pediatric IVC index limits
