Finding the Right Spirometer
Spirometers aid in the diadnosis of asthma, chronic obstructive pulmonary disease and other lung diseases. Finding a suitable spirometer is no easy task. Not only the measuring technique is important, but also the type of device (mobile or stationary) and whether the spirometer should be able to transmit the measured data to a PC.
Here is an overview of the advantages and disadvantages of the two most common measurement techniques to measure lung function, vital capacity and expiratory volume.
Pneumotachograph | Turbine | |
Measurement Technology | Determines the flow velocity in the breathing tube when the air flows through the fins | Determines the volume via the number of revolutions of the turbine |
Costs | Slightly higher purchasing price | Low purchasing price |
Advantage | High initial accuracy | Highly accurate measurement with a strong respiratory flow |
Disadvantage | Due to the humidity of the breathing air, the lamellae become dirty, which makes the measurement less accurate after some time | The turbine will not rotate until a certain air flow is reached. If the patient does not cooperate sufficiently, the measurement will be inaccurate. |

Stationary Spirometers
For general practitioners, paediatricians and pulmonologists who perform spirometry exclusively in their practice rooms, a stationary spirometer is suitable. The tabletop spirometers are often equipped with an integrated thermal printer via which the data can be printed out immediately. Some devices can also be connected to the practice PC and are equipped with a GDT interface so that the measured values can be transferred to the practice software. An example for a PC spirometer is the New Spirolab from MIR, which is supplied directly with the appropriate spirometry software.
Filters Provide Protection for Your Patients
Nowadays, special bacterial-viral filters are available for many spirometers to prevent the device from becoming contaminated during lung function testing. The disposable filters are changed after each patient so that no transmission of infection can occur. There are ready-made spirometry filters that already include the mouthpiece and those that require an additional disposable mouthpiece to be added.
Complete FlowMir disposable turbines with mouthpiece are available for the MIR spirometers. These ready-calibrated disposable turbines offer a high level of precision as they are not subject to wear and tear and provide perfect patient safety at the same time.
Portable Spirometers
Handheld spirometers for mobile use are particularly popular in occupational medicine. However, they are also ideal for use in large group practices and for lung function testing during home visits. The New Spirobank II, for example, can not only be used as a mobile spirometer, but is also suitable for PC spirometry and can be connected to an iPad. The MIR Spirobank is equipped with a USB interface and features Bluetooth. Other popular portable spirometers include the NDD EasyOne® Air spirometer or the Spirobank II Basic with high-resolution display.
