What you will find in this guide
This is I-ME's reference guide to patient monitors: what each type measures, how to choose between a basic and an advanced ICU monitor, what changes by patient group, when a central monitoring station makes sense and what it costs to run over time. It brings the topic's articles together in one starting point.
Technical content validated by I-ME's clinical engineering team (September 24, 2026). Each unit's exact configuration depends on the purchase order: always check the data sheet for the model and batch.
1. Start with the use case, not the parameter list
Before comparing models, write down the patient type, whether beds are fixed or there is transport, whether you need a central station, which parameters your protocol requires and who will operate the equipment on each shift. The practical guide to multiparameter monitors in the ICU covers that groundwork and the technical evaluation criteria.
Clinical engineering adds two criteria worth requiring in any purchase: compliance with the IEC 60601 electrical safety standards and a current INVIMA sanitary registration for the quoted model (how to check it).
2. What each catalog model measures
| Model | Standard | Optional |
|---|---|---|
| Basic Multiparameter Monitor | ECG (3/5 leads), SpO₂, NIBP, temperature | IBP (1 channel), EtCO₂, printer |
| Advanced ICU Multiparameter Monitor | ECG (3/5/12), SpO₂, NIBP, IBP (2 channels), temperature, EtCO₂ | Additional IBP, cardiac output, BIS, anesthetic gases |
| Biolight M12 | ECG, SpO₂, NIBP, temperature | IBP, EtCO₂, depending on the M series configuration |
| Biolight P15 (P Series, modular) | ECG, SpO₂, NIBP, temperature | Interchangeable modules: multi-channel IBP, EtCO₂, cardiac output, BIS, among others |
| Multi-Bed ICU Central Monitor | Measures no parameters: receives and displays data from bedside monitors (8 to 16 beds depending on configuration), with alarm review, trends and reports | — |
Abbreviations: ECG electrocardiogram; SpO₂ oxygen saturation; NIBP non-invasive blood pressure; IBP invasive blood pressure; EtCO₂ end-tidal carbon dioxide; BIS bispectral index.
3. Basic or advanced ICU?
Basic monitor. Suited to lower-acuity areas: emergency, general wards, simple post-op. Fewer invasive parameters, a simpler interface and lower purchase and consumables cost.
Advanced ICU monitor. Designed for ICUs and step-down units: native support for invasive parameters (multiple IBP, EtCO₂, cardiac output), advanced arrhythmia detection, more trend storage, better integration with central stations and electronic health records, and modular expansion.
Decision rule: if the unit needs routine invasive monitoring or treats ventilated or high-risk patients, choose advanced ICU. If volume is high and acuity low, a basic or mid-range monitor is usually enough.
4. Adult, pediatric or neonatal
One unit can serve all three groups with the right accessories and correctly configured patient profiles, but sensors, cuffs and alarm ranges differ. See monitors for adult, pediatric and neonatal ICUs.
5. Central station or standalone monitors?
From around 4 continuously monitored beds, or when nurses need to watch several beds at once, a multi-bed central station starts to pay off. Criteria and network requirements are in multi-bed central monitoring station or standalone monitors.
6. Maintenance and calibration
- Frequency: manufacturers (Biolight and equivalents) generally recommend verifying accuracy or calibrating at least once a year, or according to hours of use and hospital policy. Under heavy use, parameters such as NIBP and SpO₂ may need more frequent checks. The exact interval is in each model's service manual: there is no single figure for all equipment.
- Who does it: the supplier's technical staff, or the institution's clinical engineering team if trained and equipped with calibrated reference instruments.
- What I-ME's preventive maintenance includes: visual inspection, cleaning, accuracy verification with simulators, firmware updates, battery testing and a technical report.
7. Consumables and total cost of ownership
The highest-turnover consumables, based on I-ME's experience and manufacturer documentation:
- Disposable ECG electrodes (daily or per patient).
- SpO₂ sensors (limited lifespan; reusable or disposable depending on type).
- NIBP cuffs (wear with use; several sizes).
- EtCO₂ filters and sampling lines, where applicable.
- Thermal paper, if the monitor has a printer.
- Internal batteries: replaced every 2 to 4 years depending on charge cycles.
In most units, SpO₂ sensors and electrodes are the largest recurring cost. That is why the quote should also cover the training plan and an initial stock of consumables, alongside the maintenance contract and scheduled replenishment.
8. Before delivery
Many first-week problems come from the infrastructure, not the monitor: check the electrical installation and the network before installation. The receiving and installation checklist walks through preparation, pre-clinical tests, training and the handover record.
Next step
Browse the monitors in the catalog or talk to an I-ME advisor about your use case: number of beds, patient type, the parameters in your protocol and whether you need a central station.
