Manual Reference
Spacelabs Medical 90207/90207Q Ambulatory Blood Pressure Monitor Service Manual, P/N 070-0189-02 Rev. F; and Spacelabs Medical 90207/90217 Ambulatory Blood Pressure Monitors Operations Manual, P/N 070-0137-03 Rev. L.
Manufacturer Recommendation / AEM Status
The operations manual requires monitor pressure accuracy to be checked annually. Recalibration is necessary only when the recorder is outside the stated accuracy limit. The service manual describes periodic maintenance as exterior cleaning, replacement or recharging of the monitor batteries, and calibration for accurate operation. This page preserves the annual pressure-accuracy interval and OEM limit. Use facility policy for additional inspection frequency; do not extend the annual test through an AEM program without documented risk assessment and approval.
What This PM Procedure Covers

Step-by-Step PM Procedure
1. Remove the Recorder From Clinical Use
Action: Confirm that no patient is connected, mark the recorder as under service, and move it to a controlled work area. Disconnect the cuff and interface before cleaning or opening the battery compartment.
Expected outcome: The monitor is controlled for service and no patient can be exposed to a test inflation.
2. Verify Identity and Configuration
Action: Confirm the device is a Spacelabs 90207 or 90207Q. Record the asset tag, model, serial number, department, software or host-system configuration, interface type, cuff/hose configuration, and PM due date.
Expected outcome: The physical device and accessories agree with the CMMS record and this procedure's scope.
3. Review Service History
Action: Review prior PMs and repairs, event codes, failed or canceled readings, air-leak complaints, short battery runtime, clock/data-retention issues, drops, liquid exposure, damaged cuffs or hoses, and communication failures.
Expected outcome: Repeat faults and unresolved corrective work are identified before testing.
4. Clean and Dry the Equipment
Action: Remove batteries when required by the current cleaning instructions. Clean the recorder, carrying pouch, hose, cuff, and bladder only with agents and methods permitted by the current Spacelabs documentation. Do not immerse the recorder, allow fluid into openings, or reconnect wet parts.
Expected outcome: All reusable components are visibly clean, dry, and free of residue or fluid intrusion.
5. Perform Visual and Mechanical Inspection
Action: Inspect the housing, LCD, START/STOP switch, rear controls and communication ports, battery door, contacts, polarity markings, labels, pneumatic Luer-Lok connector, hose, cuff, bladder, hook-and-loop closure, pouch, interface cable, and accessories. Flex the hose gently and look for cracks, kinks, loose fittings, or deterioration.
Expected outcome: No crack, sharp edge, contamination, corrosion, leakage path, unreadable label, loose connection, or accessory damage is present.
6. Inspect and Service the Batteries
Action: Inspect the AA battery compartment and contacts. Install fresh or fully charged batteries of the correct type and polarity. If the 90207 loses stored data or time, refer backup-lithium-battery replacement to qualified service and follow the manual's polarity and handling instructions.
Expected outcome: Contacts are clean and secure, batteries are serviceable and correctly installed, and the recorder retains required settings and data.
7. Verify Startup, Display, Clock, and Controls
Action: Turn on the 90207 and observe its startup behavior. Inspect every visible LCD segment or message, verify date/time, operate START/STOP, and confirm the unit enters and exits its normal operating states without a persistent fault.
Expected outcome: Startup completes, the display is legible, clock information is correct, and the control responds consistently.
8. Initialize a Test Study
Action: Connect the recorder to the facility's supported ABP interface and software. Initialize a clearly identified test study using a short test schedule, then disconnect it using the approved workflow.
Expected outcome: The correct recorder is recognized, programming completes without an interface error, and the test date/time and schedule are correct.
9. Inspect Inflation, Deflation, and Pneumatic Integrity
Action: Connect a serviceable cuff around the rigid cylinder and start a reading. Observe pump sound, cuff inflation, displayed pressure, controlled deflation, fittings, and hose. Listen and inspect for abnormal leakage, sticking, erratic pressure, or unexpected interruption.
Expected outcome: The pneumatic system inflates and deflates smoothly, connections remain secure, and no abnormal leak or behavior is present.
10. Perform the Annual Pressure-Accuracy Test
Action: Verify the calibrated reference gauge reads zero with no pressure. Disconnect the cuff hose from the recorder. Connect the T-tube between the recorder's Luer-Lok connector, the reference gauge, and a cuff wrapped securely around a correctly sized rigid cylinder. Press START/STOP. The monitor should indicate approximately 165 mmHg. Compare and record monitor and reference readings as pressure bleeds down across the useful range.
Expected outcome: At every recorded point, the monitor is within 3 mmHg or 2% of the reference reading, whichever is greater, plus the accuracy of the reference gauge. If any value is outside tolerance, remove the recorder from service and send it for Spacelabs-authorized calibration or repair.
11. Interpret the End-of-Test Event Code
Action: Observe the recorder after the static accuracy test completes.
Expected outcome: An event code stating that no dynamic blood-pressure measurement was obtained is expected for this static test and, by itself, is not a failure.
12. Verify Data Transfer
Action: Reconnect the recorder to the supported interface. Download the test study and confirm the host receives the correct recorder identity, study timing, event information, and available test record. Do not retain test data in a patient chart.
Expected outcome: The recorder communicates reliably and the complete test study transfers to the intended test location.
13. Restore and Document
Action: Delete or archive the test study according to facility policy, restore approved configuration and date/time, install serviceable batteries and accessories, clean the exterior, and document readings, reference-gauge ID/calibration due date, parts, corrective action, and disposition.
Expected outcome: The recorder is complete, correctly configured, traceable, and either returned to service or clearly removed from service.
Electrical Safety Testing
The 90207/90207Q recorder is a battery-operated ambulatory monitor and does not connect directly to AC mains during patient use. Routine mains leakage and protective-earth testing are therefore not applicable to the standalone recorder. Inspect the enclosure and patient-connected pneumatic accessories for damage. Test any separately powered interface, computer, or charger under its own model-specific procedure and facility electrical-safety policy. Do not connect a patient while the recorder is attached to service or data-transfer equipment.

Copy/Paste CMMS Work Order Procedure
Use the current OEM documentation and qualified biomedical service personnel. Never test on a patient, never treat the expected static-test event code as a completed clinical reading, and never return an out-of-tolerance recorder to clinical use.
