WHO procurement baseline
WHO medical-device procurement guidance is used here as the baseline: High-Flow Nasal Cannula (HFNC) should be selected against health service need, transparent technical requirements, lifecycle affordability, and the hospital's ability to install, operate, maintain, document, and safely retire the technology.
- Start with health service need, workload, users, facility readiness, maintenance capacity, and budget reality before naming a technology or preferred vendor.
- Write requirements so bidders can respond transparently against internationally accepted procurement practice: measurable clauses, documentary evidence, declared deviations, and comparable pricing.
- Evaluate value for money across the device lifecycle, not only purchase price. Include accessories, consumables, installation, training, maintenance, spare parts, downtime, and end-of-support risk.
- Plan equipment management before delivery: inventory record, acceptance baseline, safety/performance inspection, preventive maintenance, corrective maintenance, service reporting, and user training.
Buying guide from a biomedical engineering perspective
Evaluate high-flow nasal cannula (hfnc) against the department's actual cases, peak workload, staffing, infrastructure, cleaning or decontamination process, connectivity, and tolerance for downtime. During demonstration and acceptance, require evidence for the offered configuration rather than assuming that a product-family brochure describes the quoted system.
Translate the findings below into measurable compliance fields, an itemized scope of supply, site responsibilities, acceptance records, and priced lifecycle obligations. Any clause that cannot be verified objectively should be rewritten before tender release.
