Spirometer User Manual

Order Code: SPR-BTA

The Spirometer can be used to perform a variety of experiments related to airflow and lung volume, including

  • FEV (forced expiratory volume). FEV is the volume of air exhaled after a short period of constant effort. When this test is done over a one-second interval, it is known as FEV1.
  • FVC (forced vital capacity). FVC is the volume of air exhaled by a forced maximal exhalation after a full inhalation.
  • TV (tidal volume). TV is the volume of air inhaled and exhaled at rest.

Note: Vernier products are designed for educational use. Our products are not designed nor are they recommended for any industrial, medical, or commercial process such as life support, patient diagnosis, control of a manufacturing process, or industrial testing of any kind.

What's Included

Quick Start

  1. Plug the sensor into the interface (LabQuest 3, LabQuest Mini, etc.).
  2. Prepare for data collection:
    • Vernier Graphical Analysis®: Launch the app, if necessary, and click Sensor Data Collection.
    • LabQuest® App: Choose New from the File menu.
  3. Connect the interface to the USB port on your computer. The software will identify the sensor and load a default data-collection setup. You are now ready to collect data.

Using the Spirometer

Connect the probe following the steps in the Quick Start section of this user manual.

The Spirometer can be used for inspiratory and expiratory experiments.

Always use a disposable bacterial filter with the Spirometer for all experiments. According to the manufacturer’s specs, the MicroGard® filters out more than 99% of bacterial and viral aerosols. Using a cardboard mouthpiece in addition to the bacterial filter is optional.

Note: Every person must use their own bacterial filter (and mouthpiece, if desired)—do not share these.

  1. Use a noseclip to ensure that the subject is only breathing through their mouth.
  2. Connect a disposable bacterial filter (and a disposable mouthpiece if desired) to the flow head of the sensor on the side labeled "Inlet."
  3. Hold the Go Direct Spirometer vertically and still during use

Calibrating the Sensor

You should not have to perform a new calibration when using the Spirometer. The sensor is calibrated before shipping and uses a stored calibration by default. You can simply use the appropriate calibration value that is stored in the data-collection program.

For the most accurate measurements with this sensor, we recommend adjusting the calibration using a 2 L syringe. This is a simple process that takes only a few minutes.

For further calibration information, see www.vernier.com/til/3353

Care and Maintenance

Do not wrap the cable tightly around the sensor for storage. Repeatedly doing so can irreparably damage the wires and is not covered under warranty.

Note: Every person must use their own bacterial filter (and disposable mouthpiece, if desired)—do not share or reuse these.

The nose clips should be wiped clean between uses and soaked in a mild detergent after each experiment.

How the Spirometer Works

In the center of the flow head is a plastic screen. As air is forced through the flow head, a slight difference in pressure occurs between the front and the back of the screen. A tube in front of the screen and a tube behind the screen pass the pressures to a differential pressure transducer. The greater the airflow passing through the screen, the greater the pressure differential. Airflow rate (L/s) is calculated by applying a factory-derived calibration equation to the pressure data. Volume (L) is then calculated by integrating the flow rate (L/s).
