Periodic Manufacturer’s Certification General Instructions

The purpose of these procedures is to provide detailed instructions for performing a Periodic Manufacturer’s Certification (PMC) inspection on the Narkomed 2C 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 Draeger Medical, Inc.’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.

Thefinal matrix is themost comprehensive index sortedby 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.

Rev. AB 6-1F

PMC PROCEDURE (continued) NM2C

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

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 recommendations apply to machine being inspected. (Only item number 33 - "No

Recommendations" shall apply for this certification level.) Certified with Recommendations- A numbered recommendation with a code of B applies to the machine

being examined. Conditionally Certified- A numbered recommendation with a code of BCI or BCII applies to the machine

being examined. No Certification- A numbered recommendation 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".

6-1G Rev. AB

NM2C PMC PROCEDURE (continued)

For example: A Narkomed 3 could have recommendation number 21 and failure code 61.1 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 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, 2CorGS could have 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 certificaiton level for this machine is Code A, CERTIFIED.

Code D, which means NO CERTIFICATION, also means the machine shall not receive a Periodic Manufacturer’s Certification label. The machine shall also 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® Validation’ labels have been removed.
