An oxygen supply system is not a single product; it is a chain of equipment and responsibilities from the primary source to the points of use. For hospital procurement teams, project engineers, and distributors, the critical task is to define the scope of that chain before evaluating proposals. This article focuses on how to establish that scope. It does not address the internal design of oxygen sources or the clinical aspects of oxygen therapy; those are covered in separate articles.

Start with a demand and continuity brief

Before comparing equipment, assemble a written brief with the clinical and engineering teams. This brief should answer:

• Which departments and services will be supplied, and what are their expected oxygen demand patterns?

• What existing infrastructure (piping, manifolds, generators, alarms) is in place, and what is its condition?

• What growth or changes in service are planned in the next 5–10 years?

• What are the applicable local regulations and standards that the system must meet?

The brief must also map the normal source path and every planned alternative path. For each credible interruption scenario—power loss, equipment failure, supply chain disruption—ask: what equipment remains available, how are staff alerted, and who is responsible for restoring supply? The answers depend on the specific facility and local rules; a generic product list cannot establish resilience.

Define the scope boundary: supplier, installer, hospital

A common source of confusion is where one party's responsibility ends and another's begins. For each proposed system, clarify:

• Which source components, storage connections, controls, and distribution interfaces are included?

• Who supplies and installs alarms, monitoring, and shut-off valves?

• What verification documents (e.g., test reports, certificates) are provided, and by whom?

• What training is included for hospital staff?

• What are the explicit exclusions from the scope?

Request a system diagram and a list of exclusions from each bidder. A lower equipment total can hide major site work or ongoing operating responsibilities. The goal is to compare complete scopes, not just equipment prices.

Questions to ask in an RFQ

Use these questions to structure the request for quotation and to evaluate responses:

1. Provide a system diagram showing all components from source to point of use, including backup paths.

2. List all items included and excluded from the supply, with clear demarcation of installation responsibilities.

3. Describe how the system alerts staff to a failure or switchover, and what actions are required.

4. Detail the documentation that will be provided for verification and compliance.

5. Outline the training and support offered for hospital engineering and clinical staff.

6. State the expected maintenance requirements and who can perform them.

Decision boundaries: when a single source is not enough

The configuration of any alternative source depends on the facility's risk assessment, approved continuity plan and applicable requirements. Document the interruption scenarios and the required response before comparing automatic or manual arrangements. Neither a catalogue description nor an assumption about a source's reliability can establish that the proposed reserve is adequate. These decisions belong to the qualified facility team; suppliers should describe the functions and limits of the exact configurations they offer.

Next steps for procurement

Begin by drafting the demand and continuity brief with your clinical and engineering teams. Use the RFQ questions above to gather comparable proposals. For an entry point to possible equipment, you can review Kersai's medical gas source range. Share your demand brief and source diagram so that quoted scopes can be reviewed as one system by qualified project personnel.
