What can a vitalograph measure? The Vitalograph is the standard instrument used to measure the forced expiratory volume in one second (FEVI) and the forced vital capacity (FVC). A pocket spirometer (Micro Medical Instruments Ltd) which measures FEV, and FVC as well as peak expiratory flow rate, is more portable and convenient to use.

Is a vitalograph a spirometer?
Vitalograph flow-measuring spirometers feature a Fleisch Pneumotachograph which is an established technology, developed by Professor Alfred Fleisch in Lausanne in 1953. Fleisch pneumotachograph flow measuring technology is the most accurate, precise and reliable flow measuring technology.
Is a spirometer A?
Spirometer. A spirometer is a diagnostic device that measures the amount of air you're able to breathe in and out and the time it takes you to exhale completely after you take a deep breath. A spirometry test requires you to breathe into a tube attached to a machine called a spirometer.
What Cannot be determined by a spirometer?
Functional Residual Capacity, Residual Volume, and Total Lung Capacity. These three volumes cannot be measured with a spirometer (a device that measures the volume of air being exhaled or inhaled) because there is no way of knowing the volume remaining in the lung after a maximal expiration (i.e., the RV).
Is spirometer good for lungs?
Your health care provider may recommend that you use an incentive spirometer after surgery or when you have a lung illness, such as pneumonia. The spirometer is a device used to help you keep your lungs healthy. Using the incentive spirometer teaches you how to take slow deep breaths.
What is a good number on a spirometer?
Normal values in healthy males aged 20-60 range from 4.5 to 3.5 liters, and normal values for females aged 20-60 range from 3.25 to 2.5 liters.
What is a good number on an incentive spirometer?
Most people start with a goal of 500 mL or cc. Your healthcare provider may change your goal and have you aim for higher numbers as you heal from surgery. The package your incentive spirometer came in should also have a chart. You can use the chart to set your goal based on your age, height, and sex.
What happens when you breathe into a spirometer?
Breathing slowly with a spirometer allows your lungs to inflate fully. These breaths help break up fluid in the lungs that can lead to pneumonia if it's not cleared.
What are normal levels for a spirometry test?
Interpretations of spirometry results require comparison between an individual's measured value and the reference value. If the FVC and the FEV1 are within 80% of the reference value, the results are considered normal. The normal value for the FEV1/FVC ratio is 70% (and 65% in persons older than age 65).

Our mission is to improve patient lives by designing and manufacturing market leading products and services
We have decades of experience in the manufacture and supply of respiratory diagnostic devices trusted by both medical professionals and patients alike.
Reflecting on Medica
We were at the very first Medica trade fair in Düsseldorf, showcasing our innovative spirometry technology. Both Medica and Vitalograph have come a long way since 1968.
Vitalograph provides fast accurate and simple to use telehealth devices for remote monitoring
50 + year designing and manufacturing respiratory medical devices & services to improve patient lives in over 113 countries worldwide.
The Challenge
Patients with respiratory diseases like COPD, Asthma or others need to be monitored on a regular basis. Doctors & nurses need reliable data to ensure a good and useful treatment to improve patient lives.
The Solution
For over two decades, Vitalograph has been providing products and services for remote cardio-respiratory monitoring in clinical drug trials. Vitalograph has extensive experience in supporting remote monitoring programmes for asthma, COPD, cystic fibrosis, ILD, sarcoidosis, post-transplant patients and other respiratory diseases.
Key Benefits
Ideal for remote or in-clinic monitoring for primary or secondary care or occupational health. For chronic conditions such as asthma, COPD, cystic fibrosis, ILD, post-transplant patients or any other respiratory monitoring. All useful parameters are shown, stored, and transferred.
What is the preferred technology used in Vitalograph diagnostic spirometers for flow measurement?
Today, the preferred technology used in Vitalograph diagnostic spirometers for flow measurement is the Fleisch Pneumotachograph, and for volume measurement is the Rolling Seal. We use Lilly-type screen pneumotachographs in our lab spirometers and stator-rotor flow measuring technology in our monitoring and screening devices.
Why does Vitalograph not use hot wire?
Vitalograph does not use hot wire measuring technology due to its fragility and the added complexity of patient safety incurred by including electrical parts within the flowhead. Technology. Gas flow past an electrically heated wire element causes a temperature decrease in proportion to the mass of gas and its flow.
How does a Lilly screen pneumotachograph work?
Lilly screen pneumotachographs measure flow in a similar way to Fleisch technology, employing a fine wire mesh screen with low resistance to air flow. Flow is calculated by measuring the pressure differential across a screen or series of screens. This type of device is very accurate and stable. A screen pneumotachometer is slim, allowing space in the flowhead for other features e.g. demand valves and other gas inputs and outputs making it suitable for lab spirometry requiring additional gases for tests such as DLCO and nitrogen washout.#N#The screen used in a Lilly-type Pneumotachograph is very easy to clean and service. The heated screen provides stable measurement for protracted periods of testing, although the additional electronic components in the flowhead render it less suitable for office spirometry than Fleisch flowhead technology.
What is a rotor spirometer?
Small and lightweight, the simple digital signal produced by the spin of the rotor provides accurate results for monitoring and screening of respiratory parameters such as PEF, FEV1 and FEV6. On Vitalograph devices, a simple LCD screen provides immediate results and the device stores several hundred tests that can be downloaded to view trends in patient data. This spirometric measuring technology is often referred to as a ‘turbine’, although a true turbine has a curved blade and requires no stator.
Is FEV6 a surrogate?
FEV6 is an acceptable surrogate for FVC.
Does Vitalograph use ultrasonic?
While this technology is very sensitive, Vitalograph does not use ultrasonic flow measuring technology as it is prone to errors before measurement with low flow profiling from ambient air movement and does not measure low flows accurately 3. Accuracy depends on a developed flow profile that is not found in turbulent expired air, therefore flow rates must take into account the turbulent gas flow profile; in ultrasonic technology this is corrected by software algorithms based on Gaussian probability. Turbulent airflow is overcome in Fleisch, Screen and Stator-Rotor and turbine measuring technology by design elements that manage airflow i.e. the swirl induced by the stator in stator-rotor devices, laminar flow induced by capillaries in the Fleisch and the mesh in Lilly technology.#N#Hygiene in ultrasonic devices is dependent on expensive disposable flow tubes with additional filters required for infection control.
