À

Warnings

The

Ohmeda

5250

Respiratory

Gas

Monitor

(RGM)

does

NOT

have

the

ability

to

identify

anesthetic

agents.

If

the

agent

selected

on

the

monitor

is

not the

agent

delivered

to

the

patient

circuit,

the

values

will

be

inaccurate.

If

a

mixture

of

anesthetic

agent

is

delivered,

the

monitor

may

not

indicate

accurate

values.

In

the

presence

of

alcohols,

ketones,

or

other

organic

hydrocarbon

vapors,

the

5250

RGM

will

not

indicate

accurate

readings

of

anesthetic

agent.

This

includes

their

presence

not

only

in

the

sample

line

or

patient

circuit,

but

also

ethyl

alcohol

present

in

a

patient's

bloodstream.

Handle

the

5250

RGM

with

care.

Damage

to

the

RGM

or

inaccurate

operation

may

result

from

im-

proper

handling.

Do

not

operate

the

5250

RGM

unless

it

is

prop-

erly

calibrated.

Inaccurate

patient

parameter

readings

will

result.

Keep

the

circuit

O,

sensor

attached

to

the

unit

to

assure

accuracy

of

O,

readings.

If

detached,

the

sensor

must

be

reattached

and

stabilized

for

an

equivalent

length

of

time

(up

to

a

maximum

of

14

hours)

before

recalibrating.

If

the

RGM

fails

to

respond

as

described

in

the

calibration

procedure,

do

not

use

that

portion

of

the

monitor

until

the

malfunction

is

corrected.

For the

5250

RGM

without

Agent,

use

only

Ohmeda

calibration

gas

or

calibration

gas

of

6%

CO,,

Patient

Safety—Prolonged

monitoring

or

patient

condition

may

require

changing

the

probe

test

site

periodically.

Change

the

probe

site

at

least

every

four

hours

to

reduce

the

risk

of

blistering,

skin

erosion,

or

ischemic

skin

necrosis

(especially

if

the

site

is

poorly

perfused).

Do

not

place

the

airway

pressure

adapter

on

the

expiratory

check

valve

of

the

absorber.

Blockages

in

the

tubing

circuit

can

cause

high

patient

airway

pressures

and

may

not

be

detected

by

the

RGM.

The

Minute

Volume

and

Tidal

Volume

alarms

are

usable

only

if

the

TVX

flow

cartridge

is

installed

in

the

correct

section

of

the

breathing

circuit.

Operate

the

5250

RGM

only

with

the

TVX

flow

cartridge

placed

in

the

expiratory

limb

or

com-

mon

airway

of

the

breathing

circuit.

If

the

flow

sensor

is

placed

in

the

inspiratory

limb,

the

RGM

will

not

provide

exhaled

volume

data.

If

the

5250

RGM

is

used

with

a

hanging

bellows

type

anesthesia

ventilator,

the

monitor

may

register

volumes

in

spite

of

circuit

disconnection.

Water

in

the

TVX

flow

cartridge

will

restrict

the

motion

of

its

internal

vanes

and

cause

erroneous

tidal

volume

and

minute

volume

readings.

Position

the

tubing

so

that

water

drains

away

from

the

cartridge

and

does

not

accumulate

in

it.

Exposure

of

the

sensor

clip

to

a

direct

beam

of

light

may

cause

erroneous

tidal

volume

and

minute

volume

readings.

Shield

the

sensor

clip

with

opaque

material

if

the

reading

is

suspect.

Distal

Mounting:

When

placing

the

TVX

flow

cartridge

on

the

absorber

valve,

be

certain

to

obtain

a

secure

fit,

but

do

not

force

the

cartridge

in

place

as

tightly

as

possible.

Because

the

sensor

cartridge

is

tapered,

a

secure

fit

can

be

achieved

without

excessive

force.

A

properly

placed

cartridge

is

removable

by

hand,

but

it

is

advisable

that

a

tool

(pliers

or

channel

lock

pliers)

be

available

to

remove

the

cartridge

in

case

it

has

been

jammed

on

too

tightly.

Before

every

use,

ensure

that

the

TVX

flow

cartridge

is

operational and

easily

removable.

The

flow

sensor

must

be

correctly

oriented

in

the

breathing

circuit

as

indicated

by

the

markings

on

the

sensor

clip.

The

arrows

should

point

away

from

the

patient.

If

the

clip

is

not

mounted

correctly,

the

volume

monitor

will

not

operate

properly.

Precautions

Monitor

(RGM)

provides

in

one

compact

package

a

total

respiratory

monitoring

solution

for

the

operating

room

or

intensive

care

unit.

The

RGM

uses

microprocessor

technology

to

measure

CO,,

O,,

N,O,

and

airway

pressure.

Air-

way

flow,

anesthetic

agent,

SpO,,

and patient

circuit

O,

are

monitoring

options.

All

of

these

parameters

are

displayed

on

a

4"

by

8"

flat

electroluminescent

display

screen

and

are

inte-

grated

with

an

alarm

management

system.

The

monitor

is

controlled

by

infrared

touch

controls,

and

the

display

is

removable

for

easy

access

and

viewing.

A

kit

included

with

the

monitor

contains

a

pressure

sensing

tee,

patient

sample

catheters,

airway

adapters,

a

sample

chamber

cleaning

kit

(5250

RGMs

without

Agent),

and

calibration

gas.

Optional

accessories

allow

the

monitoring

of

patient

circuit

O,

and

airway

flow.

The

SpO,

and

anesthetic

agent

monitoring

options

may

be
