Eight Technical Criteria for Choosing a Bedside Monitor

The bedside monitor is the most frequently used device in intensive care and the operating theatre; a wrong choice causes operating problems for years. When drafting a technical specification, be sure to assess the following eight criteria.

1. Patient group and parameter set

Does the device support adult, paediatric and neonatal modes? Are ECG, respiration, SpO₂, NIBP, invasive pressure, temperature and EtCO₂ standard or optional? Ask for the licence cost of options as a separate line in the quotation.

2. Screen and user interface

A touchscreen of 12 inches or larger should be usable with gloves. Waveform colour separation, alarm band visibility and menu depth save time in emergencies.

3. Alarm management

Alarm fatigue is among the main threats to patient safety. Alarm delay filters, parameter-based limits and priority classification should be available, and the alarm history should be retained for at least 24 hours.

4. Battery and transport

For uninterrupted monitoring during patient transfer, ask for at least four hours of battery life, a sturdy handle and a drop-resistant housing.

5. Central monitoring and integration

Compatibility with the existing central station, data transfer to the HIS via HL7 and network security (encrypted communication) must always be queried.

6. Sensor and consumable cost

Even if the device price looks low, the cost of single-use sensors and cuffs makes up most of the total cost. Calculate the five-year total cost of ownership.

7. Service and calibration

Authorised service time, spare parts availability and annual calibration fees should be in the specification.

8. Training and documents

User training, a Turkish manual and UTS registration data should be included in delivery. You can try Hemera Medikal's Pulsera PM-12 free of charge in your own hospital.

Common specification mistakes

Naming a brand or model in the specification, making mandatory dimensions that only one manufacturer can supply, or failing to state critical criteria such as battery life and alarm history are the most common mistakes. When the 'standard parameter set' and 'optional modules' are defined separately instead of a bare parameter count, quotations become comparable.

Verification by demo

During technical evaluation we recommend trying at least two devices in your own patient environment with the same scenario. Subjective criteria such as alarm tone, screen legibility, ease of attaching sensors and menu speed can only be measured through user experience. At Hemera Medikal we run these demos free of charge and report the results with a comparison form.

Summary

Monitor selection should not be made on device price alone. When the parameter set, alarm management, integration and five-year total cost are assessed together, the right decision can be made for both patient safety and budget. If you send us your draft specification, we will review it technically free of charge.
