Horizon Nxt®
Modular Infusion System 1 - 2 6/00
950520 Rev F
Intended Use
The Horizon Nxt® is intended for use with B. Braun Medical Horizon®
I.V. sets to regulate the flow of primary and secondary fluids when positive
pressure is required. The infusion system is capable of delivering fluid from
a negative head height (when the I.V. fluid container is lower than the
pump), and provides clinically accepted volumetric accuracy for all
standard I.V. fluids, including blood, lipids and TPN.
Positive pressure is frequently a necessity but clinical experience shows that
high pressure limits can increase the severity of an infiltration without
causing an alarm. Because there is a need to control pump pressure settings,
the Horizon Nxt has user-selectable occlusion pressure limit settings which
start at 75 mmHg and extend to 500 mmHg. At rates of 400 mL/hr and
higher, the pressure setting is automatically increased to 400 mmHg. For
epidural infusions which require higher pressures, the pump has an extended
occlusion pressure setting of 750 mmHg.
Because some infusions require multiple flow rates during the delivery
cycle, the Horizon Nxt is equipped with two automatic multiple delivery
rate modes. The Profile Delivery mode incorporates a standard ramped
delivery regimen, and the Programmable Delivery mode can be set up to
sequentially deliver up to nine user-selected volumes of fluid each at a user-
selected rate. Both modes are designed for ease of and can be adapted to
home-care settings.
The Horizon Nxt also incorporates a Dose/Rate mode which automatically
calculates the rate when dose information is entered, or the dose when rate
information is entered.
The pump is equipped with distinct audible and visual alarm signals to
indicate KVO, low battery, and actual alarm conditions.
Epidural Administration
The Horizon Nxt can be used for epidural administration of anesthetic and
analgesic drugs.
Caution
: Whenever the pump is being used for epidural infusions, the
pump’s secondary infusion features should not be used.
For epidural administration of anesthetic drugs, use indwelling catheters
specifically indicated for short-term (96 hours or less) anesthetic epidural
drug delivery.
