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 userselected 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.

Horizon Nxt®

Modular Infusion System

950520 Rev F

1-2

6/00

Page 6

For epidural administration of analgesic drugs, use indwelling catheters

specifically indicated for either short-term or long-term analgesic epidural

drug delivery.

When the Horizon Nxt® is being used for epidural infusions, the source

container and administration set should be clearly differentiated from source

containers and administration sets used for other routes of infusion.

Caution: To prevent inadvertent infusion of drugs which are not indicated

for epidural use, only Horizon microbore administration sets,

without injection sites, that are specified for epidural

administration of drugs should be used.

Following an occlusion alarm, a small amount of fluid may be delivered.

Use of a microbore set assures this is less than 0.1 mL.

The administration of drugs is restricted to those anesthetic and analgesic

drugs labeled for continuous epidural administration.

Warning: Serious injury to the patient may result from epidural

administration of drugs other than those specifically labeled for

epidural use.

Blood Infusion

The Horizon Nxt can be used for infusion of blood and blood products. For

blood infusion, a Horizon Pump Blood Set should be used. Do not attempt

to piggyback blood. The normal saline roller clamp on the blood tubing set

must be clamped off. The high viscosity of blood will cause the saline to

infuse before the blood if both clamps are left open.

q(x)°

The Horizon Nxt can be used for the periodic infusion of antibiotics,

chemotherapy or other IV infusions according to a schedule set by the user.

Assure that there is a maintenance IV infusing in the intervals between

pump infusions.

Chapter 2 PRODUCT DESCRIPTION

The Horizon Nxt® has been developed in reponse to the special needs of all

caregivers in the medical setting.

Operating Modes

The Horizon Nxt pump has five operating modes:

Standard Mode - for simple IV fluid delivery with piggyback capability.

Dose Mode - used for administration of medication where concentrations

and doses are critical. The pump will automatically calculate either the dose

or rate.

Profile Mode - offers a tapered delivery mode for infusing TPN or other

fluids requiring ramp up and ramp down time.

Program Mode - offers maximum flexibility in customizing IV fluid

administration. Up to 9 separate periods of fluid volume can be infused

sequentially.

q(x)° Mode - can be used for the periodic infusion of antibiotics,

chemotherapy or other IV infusions according to a schedule set by the user.

Assure that there is a maintenance IV infusing in the intervals between

pump infusions.

Operating States

There are 4 operating states:

Hold - silences an alarm, stops an infusion, or is a quick escape from the

menu.

Alarm - stops an infusion to notify the user of an error.

KVO - 3 mL/hr for delivery rates of 3 to 999.9 mL/hr, or the continuation

of the delivery rate for 0.1 to 2.9 mL/hr settings.

Run - starts the infusion.

Daisy Chaining

Daisy chaining allows up to 5 Horizon Nxt® or Horizon® pumps to be

plugged into each other with only one pump plugged into a wall outlet. On

the side of each Horizon Nxt pump is an electrical outlet. Only another

Horizon or Horizon Nxt pump should be plugged into that outlet.

Caution: To daisy chain more than 5 pumps, verify that the total leakage

current as a system does not exceed 100 uA.

Battery Operation

The Horizon Nxt has been equipped with an internal, rechargeable battery

which will power the pump automatically if the plug is disconnected during

use. Battery power is provided as a back-up system only, and the length of

the battery life is affected by the rate of delivery. Whenever possible, the

pump should remain plugged into an electrical outlet. The Battery Use

indicator will be lit when the pump is operating on its battery.

The pump must remain plugged into a hospital-grade electrical outlet for at

least 24 hours to fully recharge the battery from a totally discharged

condition.

Occlusion Limit

This feature lets the user change the occlusion pressure limit to 75, 100, 200,

300, 400, or 500 mmHg. At rates of 400 mL/hr and higher, the pressure

setting is automatically increased to 400 mmHg. Occlusion pressure is a

threshold value.

For Example: If the occlusion pressure is set to 300 mmHg, the pump will

infuse at the lowest pressure possible but will alarm if the

pressure required to infuse the IV fluid rises above the 300

mmHg value.

A gravity infusion of D5W with the IV container 3 feet above the IV site is

equivalent to approximately 70 mmHg.

The occlusion warning feature is optional. The occlusion warning feature

gives an audible warning (3 beeps) and a visual indication in the LED

display to let the user know an occlusion is occuring downstream from the

pump. This warning occurs 5 times at 5-second intervals before alarming

“Occlusion.” This feature is designed to alert the clinician of downstream

resistance before an alarm occurs which stops the infusion.

Caution: The higher the pressure limit, the less sensitive the pump is to

changes in fluid resistance which may be caused by positional

IV’s or infiltrations. High pressure limits can increase the

severity of an infiltration without an alarm condition.
