This is a plug-and-play PC-based spirometry device, most suited for a paediatric environment or for those with learning difficulties. The spirometer plugs directly into the USB port of a PC or laptop, without the need for an additional docking station or data uploading.

SpiroUSB performs open and closed-loop spirometry, and pre- and post-bronchodilator testing. The databases can be exported for further individual reporting. The large patient database allows results to be saved or transferred as required.
