Periodic Manufacturer's Certification General Instructions
The purpose of this manual is to provide detailed instructions for performing a Periodic
Manufacturer’s Certification (PMC) inspection on a Narkomed 2B Anesthesia machine.
A PMC consists of a complete Periodic Manufacturer’s Service procedure and a certification level
inspection based on Draeger Medical, Inc. Recommendations and equipment performance.
Additional inspections are also performed to insure proper product labeling.
Several additional documents have been created to ensure the success of this new program.
Following is a brief description of the purpose of each document.
Field Service Procedure:
Periodic Manufacturer’s Certification Forms - Part Number SP00175. This procedure illustrates
sample checklists with typical periodic maintenance items filled in, including vapor concentrations
verification tests, parts replaced, general comments and certification levels. Also included are
sample PMC labels marked to show several levels of certifications. An excerpt from DMI’s
Anesthesia System Risk Analysis and Risk Reduction is included, and also a sample of an
Executive Summary to be furnished to the hospital’s Risk Manager or Chief of Anesthesia.
Field Service Procedure:
DMI Recommendations Guidelines Index Anesthesia Systems - Part Number S010250. This
Guideline was created to provide an assessment of each machine’s certification. It contains various
comprehensive overviews of possible equipment conditions and their associated certification levels.
The first list in the Recommendation Guidelines is a reference chart for machine certification based
on equipment status. The second is an abbreviated summary of all DMI Recommendations and
Failure Codes including the Condition Number, Equipment Condition, Recommended Corrections,
Certification Code, and Tests Affected when applicable.
There is also a matrix classified as “Failure Codes” which identifies the correct manner in which to
document equipment tests that fail, or were unable to be performed due to circumstances beyond
the control of the service technician performing the inspection. (Ex: Air cylinder supply is
unavailable to perform Air High Pressure Leak test.) The Failure Codes section also indicates
suggested resolution of the situation. Failure Code numbers begin at 34 and use the same
certification levels strategy, and carry the same weight as DMI Recommendation equipment
condition codes.
The final matrix is the most comprehensive index sorted by machine model and includes Equipment
Condition, Certification Code, and DMI Recommendations. It also specifies any suggested upgrade
path including ordering information that should be taken such as installing a Bellows with
Pressure Limit Control 4109664-S01 Kit, after market modification kit to a machine not equipped
with pressure limit control.
The letters A, B, C, D and the Roman Numerals I, II are used as codes in the individual matrix for
each model of anesthesia machine. The letters A, B, C, and D are used in descending order to
indicate the certification level of the equipment. They are as follows:
A = Certified
B = Certified with Recommendations
C = Conditionally Certified
D = No Certification
6-7
RETURN TO SERVICE PROCEDURE TABLE OF CONTENTS
RETURN TO CD-ROM TABLE OF CONTENTS
NM2B PMC PROCEDURE (continued)
Roman Numerals I and II do not affect the certification level but rather are provided to give
further instructions to the end user as follows:
I = The system in its present configuration shall only be used with a CO2 monitor incorporating
an apnea warning. The operator of the system is advised to frequently scan the CO2 readings and
alarm thresholds.
II =The present configuration of equipment requires that the unit operate at all times with an
oxygen analyzer that includes a low oxygen warning. The operator of the system is advised to
frequently scan the oxygen readings and alarm limits.
Following is an explanation of machine certification levels:
Certified- No DMI Recommendations or Failure Codes apply to machine being inspected. (Only
item number 33 - “No Recommendations” shall apply for this certification level.)
Certified with Recommendations- A numbered DMI Recommendation or Failure Code with a
code of B applies to the machine being examined.
Conditionally Certified- A numbered DMI Recommendation or Failure Code with a code of BCI
or BCII applies to the machine being examined.
No Certification- A numbered DMI Recommendation or Failure Code with a code of D applies to
the machine being examined.
When multiple recommendations apply, “No Certification” would take precedence over
“Conditionally Certified” and “Certified with Recommendations”. “Conditionally Certified” would
take precedence over “Certified with Recommendations”.
For example:
A Narkomed 2B could have DMI Recommendation number 21 and Failure Code 61.1 that apply.
21 - No ventilator pressure limit control. Code is B. 61.1 - Enflurane agent is unavailable to test.
Code is BC. Correct certification for this machine is BC, which means CONDITIONALLY
CERTIFIED WITH RECOMMENDATIONS.
A Narkomed 4 could have DMI Recommendation numbers 14 and 21 apply.
14 - CO2/Agent monitor exhaust port is not properly connected to the waste gas scavenger. Code
B. 21 - No ventilator pressure limit control. Code B.
The correct certification for this machine is B, which means “CERTIFIED WITH
RECOMMENDATIONS”.
A Narkomed 2B, 2C or GS could have DMI Recommendation 30 apply. 30 - Anesthesia machine
is equipped with inhalation anesthesia vaporizers without an agent analyzer in the breathing
system. Code B.
The correct certification for this machine is B, which means “CERTIFIED WITH
RECOMMENDATIONS”.
A Narkomed 6000 could have no DMI Recommendations or Failure Codes apply. The correct
certification level for this machine is Code A, “CERTIFIED”. The correct certification for this
machine is A, which means “CERTIFIED”.
Code, D also means “NO CERTIFICATION”, also means the machine shall not receive a
Periodic Manufacturer’s Certification label. The machine shall receive a “WARNING This System Is Not Certified” label, P/N 4114857. This label shall be placed at a
prominent location on the right side of the machine after all other previous PM and
“Vigilance Audit(r) Validation” labels have been removed.
