VO₂ and cardiopulmonary exercise testing

Cardiopulmonary exercise testing measures how breathing, circulation and working muscles respond together. It can make an exercise plan more specific by showing your measured aerobic capacity and the points where effort becomes harder to sustain.

Scope and price are confirmed with the team before booking. Where a published price exists for your clinic, it is shown on the programme or clinic page.

During the test
Progressive exercise with breath-by-breath oxygen and carbon-dioxide analysis; ECG and other monitoring are included when specified by the local protocol.

The exact test or procedure, preparation, clinician and price are agreed for your location before booking.

In detail

What this adds to your care

Fitness is a functional part of health: it affects how comfortably you move through daily life. A measured assessment can help set a realistic starting point, guide training intensity and investigate exercise limitation when clinically indicated. In HLC care, the result is connected with your symptoms, goals and ability to follow the plan.

How gas analysis works

During gradually increasing exercise, a mask or mouthpiece collects breathing measurements. The system measures oxygen uptake and carbon-dioxide output; heart rate and other signals are recorded according to the local protocol. These data show how the body responds across workloads, beyond what an exercise watch can estimate.

Understanding the main outputs

Peak oxygen uptake, often expressed in mL/kg/min, summarizes the highest oxygen consumption reached in the test. Ventilatory thresholds describe changes in breathing and gas exchange as effort rises. They can inform individualized exercise zones, provided the protocol and data quality support that interpretation.

The report should also explain test effort, the reason for stopping, relevant symptoms and the reference used for comparison. A single VO₂ number is less useful without these details. An estimated “fitness age” is not a direct measurement of your biological age.

Before and after the test

Wear exercise clothes and suitable shoes, bring your medicine list and follow the team’s preparation instructions. Discuss symptoms and limitations in advance. After interpretation, the useful output is an achievable activity plan or an appropriate clinical next step, with repeat testing considered when it will answer a meaningful question.
