Patient Monitors for Clinics and Surgery Centers: New or Refurbished?

A patient monitor in a surgery center does a different job from one in a family practice. In a procedure room it tracks oxygenation, ventilation and circulation during sedation. In a clinic it may only take blood pressure, temperature and SpO2 at check-in. Settling which job the monitor will do makes the choice between new and refurbished easier, because it tells you which features you cannot do without.

This guide covers that decision. If you have already decided on a used unit, our used patient monitor checklist goes into accessories, batteries and inspection records in more detail.

Start with the care setting

Exam rooms and triage. Most clinics need spot checks rather than continuous monitoring: non-invasive blood pressure (NIBP), SpO2, pulse rate and temperature, sometimes with a printer or a link to the records system. A vital signs monitor such as the Welch Allyn Connex Spot Monitor or the GE Dinamap CARESCAPE V100 is built for this kind of work.

Procedure rooms with sedation or anesthesia. Here the monitor has to support the standard your anesthesia team works to. The American Society of Anesthesiologists' Standards for Basic Anesthetic Monitoring, last amended in October 2025, say that oxygenation, ventilation, circulation and temperature should be continually evaluated during all anesthetics, including monitored anesthesia care. The methods they describe include:

• A quantitative measure of blood oxygenation such as pulse oximetry, with the variable-pitch pulse tone and the low alarm audible to the care team
• The electrocardiogram continuously displayed from the start of anesthesia until the patient is preparing to leave the room
• Arterial blood pressure and heart rate determined at least every five minutes
• Continual end-tidal CO2 analysis whenever an endotracheal tube or supraglottic airway is in place, and every effort to monitor exhaled carbon dioxide during moderate or deep sedation
• Temperature monitoring when clinically significant changes in body temperature are intended, anticipated or suspected

That list shapes the purchase. A monitor without a CO2 (capnography) option can work well in a clinic but will fall short in a room where sedation is routine. Monitors with CO2, such as the Philips IntelliVue MX450 with CO2 module and the Criticare nGenuity with CO2, are in our multiparameter monitors range, and gas monitoring for anesthesia machines is under anesthesia monitors. Your anesthesia providers should sign off on the final parameter list, since the standards are written for them.

Recovery and step-down bays. Continuous ECG, SpO2 and NIBP are typical. If every bay uses the same model, staff learn one alarm layout and you stock one set of cables, cuffs and sensors.

Look closely at SpO2

Pulse oximetry is the one parameter almost every monitor shares, so it is worth knowing its limits. The U.S. Food and Drug Administration's pulse oximeter page notes that several factors can affect accuracy, including poor circulation, skin pigmentation, skin thickness, skin temperature, current tobacco use and fingernail polish. In January 2025 the agency issued proposed guidance, not yet final, on how manufacturers should evaluate and label pulse oximeter performance across skin pigmentation.

For a buyer this means two things. First, ask which SpO2 technology a monitor uses and keep it consistent with the sensors you already stock. Sensors such as the Nellcor DuraSensor only work with compatible monitors. Second, read the current instructions for use for the monitor and sensor you are considering, rather than an old brochure, because labeling on accuracy may change as the guidance is finalized.

Networking and cybersecurity

If you plan to connect monitors to a central station or a records system, the software version and the network design both matter.

Two public notices show why. The Cybersecurity and Infrastructure Security Agency's advisory ICSMA-20-254-01, last revised in December 2023, covers vulnerabilities in certain Philips IntelliVue MX and MP monitors running software version N and earlier. Philips' recommended mitigations include keeping the patient monitoring network physically or logically separate from the main hospital network, and for some older revisions the advisory directs owners to Philips service for an upgrade path. Separately, in January 2025 the Food and Drug Administration issued a safety communication about Contec CMS8000 and Epsimed MN-120 monitors, which it said contained a backdoor and could send patient data outside the facility once connected to the internet. The agency also said some of these monitors were being sold with wireless capability it had not authorized.

Before connecting any monitor, get the exact model and software version, check for advisories on it, and involve your IT team. An older software revision may need an upgrade that only the manufacturer can provide.

New or refurbished: how to decide

A new monitor comes with current software, current labeling and the manufacturer's warranty, and it usually has the longest support life ahead of it. It is often the better fit when monitors will connect to a central station or a records system, when you are standardizing a whole center on one current platform, or when your facility's policy calls for new equipment.

A refurbished monitor costs less and can be a good fit for standalone spot checks, overflow or recovery bays, satellite clinics and backup units, ideally on a model whose cables and sensors are still easy to buy.

It also helps to know what "refurbished" should mean. In its May 2024 guidance on remanufacturing of medical devices, the Food and Drug Administration describes servicing as repair or maintenance that returns a device to the safety and performance specifications set by the original manufacturer. It describes reconditioning or refurbishing as restoring a device to the manufacturer's original specifications, comparable to when new, which can include repairing components, installing manufacturer-provided updates and replacing worn parts. Work that significantly changes a device's performance or safety specifications, or its intended use, is remanufacturing, and remanufacturers are considered manufacturers. So ask any supplier what was done to the unit and whether it was brought back to the manufacturer's specifications.

Two more checks apply to any monitor model:

1. Recalls. The Food and Drug Administration's Medical Device Recalls database lists device recalls classified since November 2002. Search the model and ask whether any recall corrections were applied to the unit you are buying.
2. Manufacturer support. Ask the manufacturer or your service provider whether the model is still supported, and whether parts, service manuals and software updates are still available.

When the monitor arrives

Plan for biomedical acceptance testing before clinical use, whether the unit is new or refurbished. A typical incoming check covers each parameter against a patient simulator, alarm operation, electrical safety, battery run time and a record of the serial number and software version. If the supplier provides an inspection record, keep it with your own.

What to send with a quote request

• The care setting: exam room, procedure room with sedation, recovery or step-down
• Parameters needed, including whether CO2 is required
• SpO2 technology and NIBP connector, if you already have a standard
• Quantity, accessories per unit and mounting method
• Whether the monitors will be networked, and to what
• Delivery location, mains voltage and plug type

The monitors in our patient monitors category are currently listed as refurbished, and each product page states its condition. For a new unit or a model that is not listed, send an equipment sourcing request. Otherwise use our request a quote page, and see the wider refurbished equipment range.

Frequently asked questions

Do monitors in a procedure room need capnography?

If patients receive general anesthesia with an endotracheal tube or supraglottic airway, the ASA standards call for continual end-tidal CO2 analysis. During moderate or deep sedation they say every effort should be made to monitor exhaled carbon dioxide. Your anesthesia providers should confirm what your rooms need.

Is a refurbished patient monitor a sensible choice for a surgery center?

It can be, if the parameters match the room, the unit was restored to the manufacturer's specifications, recall corrections are confirmed and your biomedical team checks it before use.

Can a vital signs monitor replace a multiparameter monitor?

For spot checks in exam rooms and triage, often yes. For continuous monitoring during sedation or recovery, a multiparameter monitor with continuous ECG and, where needed, CO2 is the usual choice.

What should we check before putting monitors on our network?

Get the model and software version, look for public advisories on that model, follow the manufacturer's network security guidance, and have your IT team review the setup before connecting.
