The startup equipment list for a cardio-metabolic site: what to have in place before your first feasibility

If you are building a cardio-metabolic site from zero, have the cardiac monitoring, laboratory processing, cold storage, calibrated vital-signs equipment, and emergency readiness in place — with calibration and maintenance logs already running — before your first feasibility questionnaire. Sponsors do not qualify a shopping list. They qualify a site that can collect clean data safely on day one, and they look for records, not promises.

I run Amavita Research Services, a Miami cardiovascular trial site with more than 18,000 active cardiology patients and zero Food and Drug Administration (FDA) Form 483 findings, and I am also CEO of bioaccess, a first-in-human (FIH) contract research organization (CRO). Equipment questions are never really about the device. They are about whether your team understands the work it supports and can prove it was working correctly that day.

Start with the work, not the catalog

Do not begin by buying everything a vendor suggests. Map the work a typical protocol requires: screening electrocardiograms, repeated vital-signs measurements, timed blood draws, sample processing and frozen storage, safety monitoring, and accurate height, weight, and waist measurements. Then buy, validate, and document for those tasks.

Every device creates an obligation: a standard operating procedure (SOP), training records, maintenance, and, where applicable, calibration. A smaller, fully controlled inventory beats a crowded room full of devices nobody can produce records for.

Cardiac monitoring: the core of the site

Your first priority is a 12-lead electrocardiogram (ECG) machine that produces clear, reproducible tracings and reports the intervals sponsors need. For many cardio-metabolic protocols, that includes the Fridericia-corrected QT interval (QTcF). Check QTcF reporting before you purchase, not after — some machines require a software option, and some do not report it in the format a central reader expects. Confirm that you can export the file in the format a sponsor or central laboratory requires.

Plan beyond the resting ECG. Holter monitoring — continuous ECG recording over 24 hours or longer — is a recurring need in cardiology work. You will need recorders, leads and electrodes, analysis software or a route to a central reader, and a process for instructing participants and documenting placement and removal.

Ambulatory blood pressure monitoring (ABPM) is the other common requirement. An ABPM device records blood pressure at set intervals over a full day and night, giving sponsors a picture a single office reading cannot. Have validated cuffs in more than one size, spare batteries or chargers, and a procedure for fitting the device, explaining sleep and activity instructions, and downloading a complete record.

Whether you own Holter and ABPM units or arrange access through a partner, know before feasibility how many units are available, how quickly a failed unit can be replaced, and who analyzes the data.

Laboratory processing and cold storage

Most cardio-metabolic studies live on timed samples, so your laboratory area needs more than a counter. Plan for phlebotomy supplies, collection tubes, sharps containers, personal protective equipment, and a clean space where staff can collect, label, and process samples without mix-ups.

A refrigerated centrifuge is essential. Many protocols require samples to be spun under refrigerated conditions within a defined window after collection. It must suit your tube sizes and speeds, and staff must be trained to balance tubes, set the correct program, and document processing times.

Cold storage is where new sites most often underestimate the requirement. You need monitored storage at minus 80 degrees Celsius (−80°C) for samples that must remain deeply frozen and at minus 20 degrees Celsius (−20°C) for samples and supplies that require ordinary freezer conditions, plus monitored refrigeration where a protocol requires it. Storage should be clearly labeled and access-controlled, with continuous temperature monitoring.

Continuous monitoring means more than a thermometer someone checks when they remember. Use a system that records temperatures on an ongoing basis, sends alarms when a unit moves out of range, and reaches a named person after hours. Pair it with a written excursion procedure: what staff do when an alarm sounds, how samples are quarantined, who contacts the sponsor, and how the event is documented. Freezers fail on weekends, and sponsors will ask what happens next.

Vital signs and anthropometrics

The simplest measurements are the most repeated — and the easiest to collect badly. You need calibrated scales, a stadiometer for accurate height, and validated blood pressure devices with a full range of cuff sizes. Add a thermometer, a pulse oximeter for measuring blood oxygen saturation, and tape measures for waist circumference where a protocol requires it.

Accuracy here is not cosmetic. Height and weight drive body mass index (BMI), and BMI is frequently an eligibility criterion. Blood pressure is often both an eligibility criterion and a safety endpoint. A scale that drifts or a cuff that is too small can exclude the wrong participant, include the wrong participant, or create data a sponsor cannot use. Buy clinical-grade devices, train every operator the same way, and record measurements under the conditions the protocol specifies — for example, after a defined rest period, with the participant seated correctly.

Emergency readiness for the population you will enroll

A cardio-metabolic site enrolls people with heart disease, diabetes, hypertension, and related conditions. Your emergency equipment and training must match that risk, not a generic office standard.

Have an automated external defibrillator (AED) that is checked on schedule, an emergency medication and supplies kit appropriate to your medical coverage and local requirements, oxygen where your principal investigator (PI) and medical team determine it is required, and clear procedures for calling emergency services and transferring a participant to hospital care. Post the procedure where staff can reach it in seconds, run drills, and document them.

The PI and qualified medical staff must define and approve this setup. Equipment alone is not readiness: staff need current training, clear roles during an event, and a way to document what happened.

The part sponsors actually check: logs from day one

At qualification, the device is only the beginning. The real questions are documentary. When was it calibrated? Who maintained it? Where is the manual? Who is trained to use it?

Start a calibration and maintenance log for every device before your first study arrives. Keep a single inventory recording each device's name, manufacturer, model, serial number, location, and calibration due date. File certificates and service reports where you can retrieve them in minutes.

Calibrate on the schedule the manufacturer and your SOP require — commonly annually for scales, blood pressure devices, and centrifuges, or sooner if specified. Do not wait for a sponsor to find an overdue sticker during a qualification visit.

Write the SOPs while the team is small, covering equipment use, calibration, maintenance, temperature monitoring, excursion handling, and removal from service. Train to them and file the records. When a device fails, tag it out of service, document the failure, and use a controlled backup.

A day-one checklist

Before your first feasibility, confirm you can say yes — and show evidence — for each item:

• 12-lead ECG with QTcF reporting, export capability, and staff trained to obtain a clean tracing
• Holter monitoring access, with recorders, software or a central-reader route, and participant instructions
• ABPM access, with validated devices, multiple cuff sizes, and a download and review process
• Phlebotomy and laboratory processing area, with supplies, sharps handling, and documented procedures
• Refrigerated centrifuge appropriate for your protocol tube sizes and speed requirements
• Monitored −80°C and −20°C storage, plus monitored refrigeration, with alarms, after-hours contacts, and a written excursion procedure
• Calibrated scales, a stadiometer, validated blood pressure devices with multiple cuff sizes, a thermometer, and a pulse oximeter
• Emergency readiness approved by the PI, including a checked AED, supplies, posted procedures, trained staff, and documented drills
• A complete equipment inventory with serial numbers, calibration and maintenance logs, manuals, and service records
• SOPs and training records covering every device and process above

Build the proof, not just the room

A greenfield site cannot show a sponsor a long history of completed studies. What it can show is control. Equipment backed by logs that began on day one tells a sponsor that safety and data quality are built into your operation, not added after an award. Buy for the work, train for the protocol, and document everything.
