Introduction

Operator's Responsibility for Patient Safety

For correct and effective use of the product and in

order to avoid hazards it is mandatory to carefully

read and to observe all portions of this manual.

The design of the equipment, the accompanying litera-

ture, and the labeling on the equipment take into con-

sideration that the purchase and use of the equipment

are restricted to trained professionals, and that certain

inherent characteristics of the equipment are known to

the trained operator. Instructions, warnings, and cau-

tion statements are limited, therefore, largely to the spe-

cifics of the Dräger design. This publication excludes

references to various hazards which are obvious to a

medical professional and operator of this equipment, to

the consequences of product misuse, and to potentially

adverse effects in patients with abnormal conditions.

Product modification or misuse can be dangerous.

Dräger, Inc. disclaims all liability for the consequences

of product alterations or modifications, as well as for

the consequences which might result from the combi-

nation of this product with other products whether sup-

plied by Dräger or by other manufacturers if such a

combination is not endorsed by Dräger, Inc..

The operators of the ventilator system must recognize

their responsibility for choosing appropriate safety mon-

itoring that supplies adequate information on equipment

performance and patient condition. Patient safety may

be achieved through a wide variety of different means

ranging from electronic surveillance of equipment per-

formance and patient condition to simple, direct obser-

vation of clinical signs. The responsibility for the selec-

tion of the best level of patient monitoring lies solely

with the equipment operator. (See also page 12, "Medi-

cal Attention").

Warranty Introduction

Operating Instructions MicroVent

General WARNINGS and CAUTIONS

WARNING !

If a fault is detected in the ventilator and its life-

support functions are in doubt, ventilation must

be started without delay with an independent

ventilation device (resuscitation bag) - using

PEEP and/or increased inspiratory O2concen-

tration where necessary and appropriate. The

unit should then be removed from use and ser-

viced by an authorized service technician.

WARNING !

Whenever a patient is connected to the ventila-

tor, constant attention by qualified medical staff

is required in order to provide immediate cor-

rective action in case of a malfunction.

The operator shall not rely on the built- in moni-

toring of the ventilator and must always assume

full responsibility for proper ventilation and pa-

tient safety in all situations.

WARNING !

DANGER, risk of explosion if used in the pres-

ence of flammable anesthetics.

This device is neither approved nor certified for

use in areas where combustible or explosive

gas mixtures with air or with nitrous oxide are

likely.

used for the purpose specified under "Intended

Use" (see page 12) and in conjunction with

appropriate airway monitoring (see page 6).

Observe all WARNINGS and CAUTIONS as ren-

dered throughout this manual and on labels on

the equipment.

Introduction Definitions

General WARNINGS and

CAUTIONS

Operating Instructions MicroVent

CAUTION !

Always use elbow connector for accurate flow

measurement.

WARNING !

Always use medical grade oxygen and air that is

dry and free from dust and oil. Contaminated gas

may cause ventilator malfunction.

WARNING !

Do not install flow restricting valves or flow me-

ters into the high pressure gas supply. Equip-

ment malfunction might result.

WARNING !

• Always use extreme caution when using oxygen!

• Oxygen intensely supports any burning!

No smoking, no open fire in areas where oxygen

is in use!

• Always provide adequate ventilation in order to

maintain ambient O2concentrations < 24 %

• Always secure O2cylinders against tipping, do

not expose to extreme heat.

• Do not use oil or grease on O2equipment such as

tank valves or pressure regulators. Do not touch

with oily hands. Risk of fire!

• Open and close valves slowly, with smooth turns.

Do not use any tools.

WARNING !

Treatment of batteries:

Do not throw into fire! Do not force open!

Do not attempt to recharge alkaline batteries!

Danger of bodily injury.

Follow all local, state, and federal regulations

with respect to environmental protection when

disposing of batteries.

WARNING !

Do not use antistatic (electrically conductive)

patient circuits or tubing.

Precautions During Preparation

WARNING !

Always use an independent oxygen analyzer to

monitor inspiratory oxygen concentrations.

WARNING !

Always verify that valve membrane is installed in

correct orientation. Ventilator malfunction will

occur if silicone membrane is reversed.

CAUTION !

Maintenance

In case of malfunction of this device, contact your

local DrägerService or our Factory Authorized

Technical Service Center.

The device must be inspected and serviced (pre-

ventive maintenance) by competent and factory au-

thorized technical service representatives at regu-

lar 6 month intervals. A record must be kept on this

preventive maintenance. We recommend obtaining

a service contract through your vendor.

Maintenance or repair of the MicroVent shall be per-

formed only by Dräger authorized technical service

representatives.

CAUTION !

Traceability

Federal Law in the United States requires tracea-

bility of this equipment. Please return the self ad-

dressed registration card included with the product

and fill in the required information.

CAUTION !

Restriction of Distribution

Federal Law and Regulations in the United States

and Canada restrict this device to sale by or on the

order of a physician.

General WARNINGS and

CAUTIONS (cont'd)

Precautions During Preparation

Introduction

Operating Instructions MicroVent

Precautions During Care

WARNING !

Water remaining in the ventilator valve or in the

pressure sensing lines for flow measurement

may cause ventilator malfunction.

WARNING !

Always follow accepted hospital procedures for

handling equipment contaminated with body

fluids.

WARNING !

Do not block air intake. Ventilator malfunction

will result.

WARNING !

Continuous or intermittent audible alarms re-

quire immediate operator attention to avert or to

prevent development of situations with the pos-

sibility of patient injury.

WARNING !

Automatic patient ventilation, volume measure-

ment, and alarms are not functional in case of a

loss of electric power!

Spontaneous breathing through the integrated

demand valve, however, is still possible in that

situation,

Immediately start ventilating patient with inde-

pendent manual ventilation device (resuscita-

tion bag) using PEEP and/or increased inspira-

tory oxygen concentration where necessary and

appropriate.

Precautions During Operation

WARNING !

Use CPAP mode only for patients who have suffi-

cient spontaneous breathing.

WARNING !

Observe pressure gauge in order to identify im-

proper ventilation. Operator must always be

ready to intervene if alarm indicates a situation

dangerous to the patient.

WARNING !

Always use ventilator that has been cleaned and

disinfected and has been successfully tested to

be ready for operation.

CAUTION !

For safety reasons, a battery pack must always be

installed, even when using external power sup-

plies!

CAUTION !

Do not pressurize the connector for pressure

sensing lines. It might destroy the internal sensor.

CAUTION !

Always use DC/DC converter 84 13 017 when

charging from a DC source.

CAUTION !

Always use AC adapter 84 12 709 for connecting

device to 120 V AC line voltage.
