Spirometers

Whether you’re looking for a PC Based Spirometer or a hand-held spirometer machine, Numed Healthcare offer the whole package for your GP surgery or clinic. We supply and support a range of desktop and PC based spirometers from leading brands, such as CareFusion (Micro Medical), NDD and Medchip.  

Designed for everyday use within the GP surgery or health centre, many of our spirometers are fully integrated with the EMIS, TPP SystmOne and Vision NHS GP clinical systems.

One of our best-selling portable spirometers is the SpiroConnect spirometer. With a range of innovative enhancements, SpiroConnect is one of the most accurate and easy-to-use spirometers on the market. Its proven turbine technology creates less rotational resistance, making it more sensitive to low flow rates. What’s more, its advanced antistatic plastic improves measurement accuracy, making it easier to attain precise spirometry test results.


What is a spirometer used for? 

A spirometer is a medical device used to perform breathing tests on patients with respiratory symptoms. It is used to diagnose, assess the severity, and monitor the progression of a variety of respiratory diseases.  

What does a spirometer measure?

A spirometer measures: 

Relaxed (or slow) Vital Capacity (VC) - The volume of air that can be slowly expelled from the lungs from a point of maximal inspiration to maximum expiration.

Forced Vital Capacity (FVC) - The volume of air that can be forcibly expelled from the lungs from a point of maximal inspiration to maximum expiration. 

Forced Expiratory Volume in 1 second (FEV1) - The volume of air that can be forcibly expelled from the lungs from a point of maximum inspiration in the first second of an FVC manoeuvre.

FEV1/FVC ratio or FEV1% - The FEV1/FVC ratio is the FEV1 expressed as a percentage of the FVC (or VC if this is greater).

How do I quality control check my SpiroConnect? 

Considering spirometry tests are used to measure lung function and diagnose potential respiratory conditions, accuracy is key. SpiroConnect has the very latest vertical turbine transducer to measure flows and volumes. This means that the calibration of SpiroConnect will not drift from its factory setting and you can be assured of accurate measurements. However, to conform to the current European guidelines for spirometry testing, the calibration of all spirometers should be regularly verified with a 3 litre calibration syringe.
