A completed room may still be unready. Acceptance begins when performance no longer depends on assumptions.
What integrated operating room commissioning must demonstrate
Installation answers “is it fitted and connected?”. Commissioning checks “does it perform as specified?”. Clinical acceptance adds “can staff use it clearly in the real workflow?”. Combining these layers produces long reports that fail to show what was actually tested.
The WHO distinguishes performance and safety inspections within a maintenance strategy. The same approach should be applied during commissioning: identify the asset, test its behaviour, record the configuration and specify which checks must be repeated.
| Level | Verifiable question | Evidence for acceptance |
|---|---|---|
| Installation | Does it match drawings, specifications and contracted scope? | As-built drawings, inventory, certificates and point list. |
| Function | Does each element operate within the intended criterion? | Measurements, reports and recorded configuration. |
| Integration | Does the signal travel end to end while retaining priority and context? | End-to-end test and event log. |
| Use | Can staff reach, interpret and operate what they need? | User simulation and approved adjustments. |
| Continuity | Is a failure visible, and can the service continue or recover safely? | Degraded-mode, recovery and return test. |
Before testing: set the scope, configuration and criteria
A test loses value if the installed version changes the next day. Before joint testing, set the inventory, current drawings, software versions, active interfaces, agreed thresholds and permissions. This reference configuration makes the test repeatable and links any later deviation to a specific change.
The scenario must also be defined. An unloaded outlet, an alarm viewed from one metre or a pendant moved without trolleys and cables does not reproduce working conditions. The protocol should state the initial conditions, action, expected result, measuring instrument, tolerance and person responsible for sign-off.
Set the configuration
Inventory, drawings, versions, interfaces, permissions and responsible parties.
Test at each level
Unit, integrated, user and controlled-failure tests.
Hand over for use
Test reports, outstanding issues, training, technical support and post-opening review.
Acceptance matrix: from the test to the responsible person
This matrix does not replace the project protocol. It organises the decisions required for a test to be meaningful and assessed without ambiguity.
| Area | Contextual test | Criterion | Participants |
|---|---|---|---|
| Power | Expected load, identification, backup and simulated loss. | Outlets and priorities match design; interruption is detected. | Engineering, installer, clinical engineering. |
| Medical gases | Identity, pressure, tightness, alarm and isolation. | Results meet the applicable protocol and points are identified. | Authorised installer, engineering, users. |
| Ventilation | Environmental conditions and alarms in intended states. | Parameters and records match the validated design. | Engineering, infection control, maintenance. |
| Control and integration | Command, signal, confirmation, permissions and traceability. | No ambiguous action; each event is identified and recorded. | IT, supplier, clinical engineering. |
| Ergonomics | Workflow with table, trolleys, monitors, cables and users. | Reach, sightlines and movement avoid preventable interference. | Clinical team, health and safety, engineering. |
| Degraded mode | Loss of network, display, interface or non-essential power. | Failure is visible; agreed functions continue or recover. | IT, engineering, clinical staff, suppliers. |
| Documentation | Reconstruct a configuration and report an incident. | Versions, contacts, backups, manuals and responsible parties are available. | Quality, maintenance, department management. |
The most useful test does not show that something powers on. It shows what happens when a dependency disappears and who must respond.
Four tests that often uncover late problems
1. End-to-end alarm path
Trigger a controlled condition and verify origin, priority, display, audibility, acknowledgement and logging. Where alarms are centralised, loss of the secondary interface must not remove the primary signal. This connects with the management of alarm fatigue in ICUs and operating rooms.
2. State change and return
The test must cover entry into manual or degraded mode and the return to normal operation. Check how the change is indicated, which functions remain available, who can activate it and whether the system returns to normal without retaining a temporary configuration by mistake. Operational continuity depends on staff knowing this procedure.
3. Ergonomics under realistic load
Repeat workflows with the intended accessories, loaded trolleys, monitors, cables and working positions. The purpose is to locate collisions, blind spots, unreachable controls and strain on connections. A correct drawing may fail when every object occupies its real volume.
4. Documentary recovery
The team responsible for operating the room must be able to identify a version, retrieve the final drawing, restore a configuration and find the procedure and contact for reporting an incident. If only the installer can reconstruct the system, the technical handover is incomplete.
Applying acceptance to HERMES, Q Panel and supply units
Within the Tedisel environment, HERMES can centralise operating-room controls and data; Q Panel can integrate displays, video, data, alarms and electrical components; and ceiling supply units such as Atlas distribute services and support project-specific accessories.
Acceptance must be limited to the contracted functions. For a panel, this means checking every installed component, maintenance access and correspondence with the final drawing. For software, it means testing permissions, commands, alarms, logs and behaviour when communications are lost. For a suspended unit, it means checking movement, brakes, configured load, outlets, accessories and the absence of interference in the intended scenario.
The Hospital Universitario de Guadalajara appears in Tedisel’s portfolio with Ares, Atlas, HERMES and Q Panel. When several systems form part of the same installation, acceptance must examine the complete assembly and its interfaces, as well as each product family separately. The public page documents the installed products; it does not attribute a specific commissioning protocol to the hospital.
Errors to avoid before acceptance
| Error | Consequence | Resolution criterion |
|---|---|---|
| Signing off with one undifferentiated list of outstanding issues. | Cosmetic defects and operational risks are mixed. | Classify each issue by effect, risk, responsible person and date. |
| Testing each system in isolation. | Interfaces fail during the first joint use. | Add end-to-end scenarios. |
| Accepting changes without updated drawings or versions. | The reference configuration cannot be reproduced. | Update the handover file before sign-off. |
| Training without task assessment. | Attendance does not prove the ability to perform the required tasks. | Check actions, alarms and incident-reporting procedures for each role. |
| Skipping the post-opening review. | Usability issues emerge without an adjustment route. | Set a review after the first weeks of operation. |
What acceptance should cover before the operating room opens
The scene places the checks in an integrated room and separates five areas: utilities, control and interfaces, ergonomics, degraded mode and records. Project stakeholders should document and review every result before clinical opening is authorised.
Clinical opening requires a known configuration
Commissioning ends with the handover of the accepted documentation and configuration. The hospital should receive the evidence, outstanding issues, responsible parties and technical-support arrangements. This information allows the environment to be maintained, updated and recovered without relying on undocumented instructions.
Cybersecurity in connected hospital equipment adds controls for inventory, access, updates and recovery. NHS technical documents for specialised ventilation and medical gas pipeline systems show why verification must be discipline-specific.

Frequently asked questions about operating room commissioning
What are acceptance tests for an integrated operating room?
They are documented checks showing that services, equipment, interfaces and procedures work in the agreed configuration and under representative scenarios before clinical use is authorised.
Who should approve commissioning?
Approval must be assigned according to the scope of each test. Engineering validates services; clinical engineering validates equipment; IT validates connections and access; and clinical users validate operational scenarios.
Is testing each device separately enough?
No. Unit tests verify components, while an integrated operating room also needs end-to-end tests covering alarms, interfaces, network loss, recovery and return to normal operation.
Which documents should be available at handover?
At minimum: final scope, current drawings and configurations, inventory, test reports, outstanding issues, responsible parties, manuals, training records, backups, support contacts and review dates.
How should open issues be managed?
Each issue needs a risk assessment, operational effect, compensating measure, responsible person, target date and a decision on whether it prevents the room from opening. The list should assign a priority and responsible person to every issue.
What is the role of HERMES and Q Panel in acceptance?
HERMES and Q Panel may concentrate control, visualisation and technical elements depending on configuration. Acceptance must test the contracted functions, interfaces and failure behaviour; neither replaces validation of the complete system.
