Fig 1 Cross-sectional view of the right IJV in a 3.2 kg infant. Ultrasound probe placed transversely to the neck. Inset: CL, clavicle. Ultrasound image: IVJ, internal jugular vein; CA, carotid artery; SCM, sternocleidomastoid muscle. Dotted line: A–A, anterior–posterior diameter of IJV via SAX view. Ellipse: B–B, medial–lateral distance of the ellipse; A, area (CSA) within the ellipse; C, circumference of the ellipse. Dotted line: C–C, depth of IJV from the skin surface.

Fig 2 Cross-sectional view of the right SCV in a 4 kg infant. Sagittal ultrasound probe placed below the clavicle. Inset: CL, clavicle. Ultrasound image: SCV, subclavian vein; SCA, subclavian artery; PL, pleura; PM, pectoral muscles. Ellipse: A–A, cranial–caudal distance of the ellipse; A, area within the ellipse; C, circumference of the ellipse. Dotted line: B–B, anterior–posterior diameter of SCV via SAX view.
