Best Used Patient Monitors: Prices, Reviews & Where to Buy (2026)
Patient monitors are among the most cost-effective used medical equipment purchases you can make. A Philips IntelliVue that costs $12,000–$18,000 new can be sourced refurbished for $1,500–$4,500 — with identical clinical performance. For clinics, surgery centers, veterinary practices, and global health programs, the secondary market for patient monitors is deep, competitive, and well-supplied.
This guide covers the top brands, parameter configurations, pricing benchmarks, and exactly what to look for before you buy.
What Is a Patient Monitor?
A patient monitor (also called a bedside monitor or vital signs monitor) continuously measures and displays physiological parameters. The most common parameters are:
- SpO2 — Blood oxygen saturation (pulse oximetry)
- ECG/EKG — Heart rhythm (1, 3, 5, or 12-lead)
- NIBP — Non-invasive blood pressure
- Temp — Temperature (skin, core, or esophageal)
- EtCO2 — End-tidal CO2 (capnography)
- IBP — Invasive blood pressure (arterial line)
- Resp — Respiratory rate
A 5-parameter monitor covers SpO2, ECG, NIBP, Temp, and Resp — the standard for general med/surg and PACU. Full multiparameter units add EtCO2, IBP, and BIS for critical care.

Spacelabs has a strong presence in telemetry. Welch Allyn (now Hillrom/Baxter) makes excellent vital signs monitors for clinic and physician office use. Masimo is the gold standard for SpO2 accuracy.
Parameter Configuration Guide
When buying used, the monitor's configuration (which parameters are active) matters more than the hardware model. Parameters are often software- or module-licensed.
| Parameter | Why It Matters | Adds to Price? |
|---|---|---|
| EtCO2 | Essential for intubated patients; OR/ICU standard | +$300–$800 used |
| IBP (2-channel) | Arterial line monitoring; critical care | +$200–$500 |
| 12-Lead ECG | Diagnostic-quality interpretation | +$200–$600 |
| BIS/Entropy | Anesthesia depth monitoring | +$400–$1,000 |
| Cardiac Output (C.O.) | ICU hemodynamics | +$300–$700 |
| Temperature (2-channel) | Core vs. skin, or two-patient comparison | Minimal |
Pro tip: Always ask the seller to demonstrate every parameter live or on video. Modules can fail independently — a monitor priced cheaply because "IBP doesn't work" might cost more to repair than the savings justify.

What to Look For: Pre-Purchase Checklist
Screen & Display
- No dead pixels, burn-in, or discoloration
- Touchscreen responsive (if applicable)
- Waveforms display cleanly on all active parameters
Alarms & Audio
- All alarm tones function correctly
- Visual alarms (flashing indicators) work
- Alarm limits are adjustable
Connectivity
- Network port functional (for central monitoring integration)
- Module slots undamaged
- Battery backup tested (>20 minute charge minimum)
Accessories
Confirm whether the following are included — replacement costs can exceed the monitor price:
- SpO2 probe and cable
- NIBP cuff(s) and hose
- ECG lead set (5-lead or 10-lead)
- Temperature probe
- Power supply / AC adapter
Biomed Certification
For clinical use, insist on:
- Current PM certificate (within 12 months)
- IEC 60601 electrical safety test passed
- Calibration certificate for NIBP
Telemetry vs. Bedside Monitors
Bedside monitors are fixed units connected to the patient at the bedside. They provide the richest parameter set and are standard in ICUs, ORs, and EDs.
Telemetry monitors are worn by ambulatory patients and transmit wirelessly to a central station. Used telemetry systems (Philips IntelliVue Telemetry, GE ApexPro) can provide excellent value for step-down and med/surg units — but require compatible central station software.
For most buyers, bedside monitors offer better standalone value on the secondary market.
Transport Monitors
For ambulance, inter-facility transport, or procedure rooms, compact transport monitors are essential. Key models:
- Philips X2/X3 — The gold standard for transport; can dock with IntelliVue host monitors
- GE Dash 4000/5000 — Rugged, portable, excellent used availability
- Zoll X Series — Combined monitor/defibrillator; see our defibrillator guide
- Mindray T1 — Excellent multiparameter transport monitor
Veterinary Use
Used human patient monitors are widely used in veterinary medicine — they measure SpO2, NIBP, ECG, and temperature in animals with minimal modification. Mindray and GE units are especially popular in vet practices. Smaller clinics also use the patient supply equipment at patientsupply.net for DME-grade vital signs monitoring.

Frequently Asked Questions
Q: What parameters do I need in a used patient monitor? A: For general clinical use, a 5-parameter monitor (SpO2, ECG, NIBP, Temp, Resp) is sufficient. Add EtCO2 for any intubated patients (OR, ICU, ED). Add IBP for critical care or arterial line patients. For procedure rooms and clinics, SpO2 + NIBP + ECG covers the majority of cases.
Q: Can I use a used human patient monitor for veterinary purposes? A: Yes, with some caveats. SpO2, ECG, and temperature work well for most animal species. NIBP cuffs need to be appropriately sized. Some sensors (lingual SpO2 probes for dogs, for example) are species-specific. Verify the monitor's NIBP algorithm works with your patient population.
Q: What is the lifespan of a used patient monitor? A: Well-maintained patient monitors typically have a 10–15 year service life. Most units on the used market are 3–8 years old and can provide 5–10 more years of reliable service with proper preventive maintenance.
Q: How much should I pay for a used Philips IntelliVue? A: It depends on the model and configuration. Older MP20/MP30 units in as-is condition can be found for $300–$800. A fully refurbished MX450 with EtCO2 and IBP from a reputable dealer will run $3,500–$5,500. Budget models from the iPM and Spacelabs lines offer excellent value for non-ICU applications.
Q: Do used patient monitors come with software licenses? A: Sometimes. Many Philips and GE monitors have software options that are licensed per unit. Always ask the seller to confirm which software options are active and whether licenses transfer. Some features (e.g., 12-lead interpretation, BIS) require active software licenses to function.
