Interventions
Inferior vena cava (IVC) collapsibility index (IVCCI) will be measured. The IVCCI is calculated using the following formula: IVCCI = (maximum IVC diameter - minimum IVC diameter) / maximum IVC diameter \* 100
The Inferior vena cava (IVC): Ao index will be derived by taking the ratio of the maximum IVC diameter during expiration and the maximal abdominal aortic diameter during systole. \- The caval aorta index (IVC/Ao) is calculated using the following formula: IVC/Ao index = IVC diameter / aortic diameter.
