Spirometry is an essential pulmonary function test that should be available at every general practitioner’s office. It provides objective information for lung health monitoring and the diagnosis of lung conditions , both in primary care and in pulmonology. Let us have a look at essential spirometry measurements and what they mean, the parameters that can be calculated on that basis, and the recommended reference values for interpretation.
All this constitutes a basis for accurate spirometry. Enhanced by digital technology, spirometry is entering a new era where it is becoming more time-efficient and more user-friendly not only towards the patient, but also those performing and interpreting it. The MESI mTABLET offers digital spirometry solutions for travelling health professionals (FEV6: Quick Spirometry), the GP office (Spiro: Primary Spirometry) and pulmonology specialists (Spiro+: Advanced Spirometry).
In this blog you will learn:
Spirometry measurements range from basic to advanced, depending on the type of the spirometry measurement device and the field in which it is used (primary care, secondary care).
The FEV6 basic spirometry measurement and the parameters calculated on its basis are used for a basic lung evaluation, for example at home visits by nurses. Only the expiration part of the patient’s lung function is monitored, so only the expiration and not the inspiration will be shown on the graph display(s).
In FEV6, the speed of the spirometry exam is at the forefront. This is why the maneuver of the patient (i.e. exhaling and inhaling according to the nurse’s or doctor’s instructions) also takes less time; while the full FVC maneuver can take up to 15 seconds, the FEV6 measurement can only take 6 seconds. This makes it faster and also easier for the patient. Let us see what FEV6 means and what parameters it can show.
FEV6 (forced expired volume in 6 seconds): It shows the amount of forced vital capacity (FVC, i.e. the maximum amount of air expired forcefully from a fully inflated lung) expired by the 6th second of expiration. Measured in litres BTPS. In a healthy person, the FVC and FEV6 values are about the same. 
Again, only the expiration part of the patient’s lung function is monitored. At this level, spirometry is often used for asthma monitoring, so pre- and post-drug measurements will be carried out. Also known as bronchodilatation, this test is performed before and after the asthmatic patient has used a bronchodilator inhaler or nebuliser to open their lungs.
A specialist pulmonological examination requires more complex information, including the data on both the expiratory and inspiratory parts of the lung function (aka full-loop spirometry). This is possible due to closed-loop technology, which enables the patient to both breathe in and expire with the mouthpiece in their mouth rather than breathing in freely and then blowing into the mouthpiece. This enables a lot more measurements and parameter calculations.
No spirometry result can be read without reference to a prediction model. Prediction models are reference values that represent healthy zone for each individual according to guidelines valid in a specific country.
There are 5 different Global Lung Initiative (GLI) prediction models are becoming standard, but several others are still used as well. They are based on age, sex, height and ethnicity.
There are many different devices for spirometry, of which there are many different types, from simple ones to large, complex devices designed for comprehensive assessment of pulmonary issues.
The advent of digital technology has brought many advantages to diagnostic measurements, including that of spirometry. The MESI mTABLET SPIRO is a digital diagnostic module for spirometry, with the following advantages for all levels of healthcare:
The MESI offers three different spirometry solutions.
Offering basic spirometry measurements, Quick Spirometry is an ideal solution for home visits. It offers enhanced visual display of the Flow-Volume curves and various parameters with automatic analysis:
Quick Spirometry is available as an app after purchasing the MESI mTABLET SPIRO diagnostic module, which offers Primary Spirometry – a comprehensive spirometry package for primary care.
This diagnostic measurement tool covers all spirometry needs in primary healthcare:
The most versatile digital spirometer for specialists.
Advanced Spirometry is available as an app after purchasing the MESI mTABLET SPIRO diagnostic module, which offers Primary Spirometry – a comprehensive spirometry package for primary care.
The MESI mTABLET SPIRO is a diverse tool that gives the primary care physician and the pulmonologist a tool for comprehensive assessment of a patient’s health beyond diagnosing possible pulmonary issues.
