Brief Summary:
This study aimed to know the consistency of intravascular volume measurement using USG of IVC compared to VPW chest x-ray

Condition or disease Intervention/treatment Phase
Unintubated Patients in ICU and Resuscitation Room Diagnostic Test: Inferior vena cava (IVC) diameter using USG Diagnostic Test: Vascular pedicle width (VPW) Not Applicable

Detailed Description:
Approval from Ethical Committee of Faculty of Medicine Universitas Indonesia was acquired prior conducting the study. Validation and reliability test were done for USG operators by assessing IVC in 20 patients supervised by intensivists. Subjects were given informed consent before participating in the study. Subjects underwent the chest x-ray examination with supine position. The measurement of VPW was done by radiologists, considered normal if the value is 53 ± 5 mm, overload if VPW > 71 mm. The subjects then underwent the IVC diameter measurement using USG Philips En Visor C, with transthoracal subcostal approach. The result is considered normal if IVC diameter is 1.5 - 2.5 cm and overload if >2.5 cm, otherwise the subjects is excluded. If the IVC can not be done, subjects will be excluded.

Arm Intervention/treatment
Experimental: Inferior vena cava (IVC) diameter
subjects underwent IVC diameter measurement after VPW measurement
Diagnostic Test: Inferior vena cava (IVC) diameter using USG
IVC diameter is measured from the distal of right hepatic pain and inferior vena cava meeting point using Philips En Visor C USG.

Active Comparator: Vascular pedicle width (VPW)
Supine chest x ray was done and the VPW is assessed by radiologists.
Diagnostic Test: Vascular pedicle width (VPW)
VPW is measured by drawing a line from the left subclavian artery exit point from aorta perpendicular to the point where superior vena cava crosses with right bronchi.

Primary Outcome Measures :
  1. Intravascular volume measurement [ Time Frame: IVC is measured 30 minutes after VPW ]
    Measured by VPW and IVC diameter using USG
