Spirometer Pod

Spirometer Pod

The Spirometer Pod is suitable for differential pressure measurements of dry non-corrosive gases such as air flow and pulmonary function measurements. The Spirometer Pod is a compact respiratory signal conditioner for use with PowerLab data acquisition systems. The Spirometer Pod is a differential pressure transducer with low noise and low air flow resolution, which interfaces with respiratory flow heads to measure air flow rates for humans and animals. When used with ADInstruments respiratory flow heads and the Spirometry LabChart Extension (software), compensated volume and forced respiratory parameters can also be determined.

Transducer Capability:

The Spirometer Pod is suitable for operation with ADInstruments respiratory flow heads including MLT1L, MLT10L, MLT300L and MLT1000L.
Hans Rudolph flow heads are also compatible with the Spirometer Pod.

System Compatibility:

The Spirometer Pod connects to any PowerLab hardware units with Pod ports (8-pin DIN inputs). PowerLab and MacLab (except 4s, 8s and 16s) units without Pod ports can connect to Pods by using the FE305 Pod Expander.

The Spirometer Pod is supported by the following versions of LabChart and Scope software:

WINDOWS

• LabChart v3.4.8 or later

• Scope v3.6.3 or later

MACINTOSH

• LabChart v3.6.3 or later

• Scope v3.6.3 or later

Note: Earlier software versions do not support Pods.

Theory of Operation:

Air flowing through a wire mesh in the respiratory flow head creates a pressure difference on either side of the mesh. A larger airflow creates a greater difference. This pressure difference is transmitted to the Spirometer Pod via two tubes and converted to an analog voltage proportional to the air flow rate. The Spirometer Pod also provides low-pass filtering fixed at 30 Hz.

Stacking and Unstacking Pods:

Pods stack by clicking into place on top of each other. To separate stacked Pods, push the top Pod towards the back and then pull them apart from the back.

Caution - The Spirometer Pod?s differential pressure sensor is position and movement sensitive. For consistent recordings always keep the Pod in the same orientation. Keep the Spirometer Pod on a stable surface while recording. Any movement will result in unwanted artifacts.
