Static NAT with DHCP Client/ Failover router. I convinced the Call Center to buy a new router for their main and replace the Netgear with the 3825. We use the 3825 for Failover only. Also Nat overload for the whole inside address range.. The backup router is a DHCP client and the outside WAN ip changes from time to time. It's on a network with a /192 mask. We cannot get a static ip for the back up.
Bolus injections are acceptable for studies in which the aim is to improve endocardial border delineation (EBD), perform left ventricular opacification (LVO) or enhance Doppler signals. We recommend that it is avoided during perfusion studies, when an infusion is preferable.
An intravenous bolus is often used because the medication needs to get into the bloodstream quickly in order to correct a life-threatening condition. Individuals who have low urine output are not good candidates for an intravenous bolus.
