Someone cranked the gate overnight

Handover

V-AV for Harlequin, balanced on both limbs last night with a flow probe on each return. Overnight someone cranked the venous-return gate nearly shut. Qven 0.3 L, Qart 4.2 L. Right-hand sat is sliding and the venous limb looks dark and sluggish. A nearly occluded limb is a clot factory.
