I have been asked to give my opinion of the NDD Easy One Air Spirometer for a group that is looking to buy a large number of them. The unit is a small, hand held Ultrasonic Spirometer that has a display and stores up to 10,000 pt tests.
I have not seen one in person but I am quite familiar with other Pulmonary Function Equipment, I was just wondering if anyone has seen this unit or had any experience with it.
My concern is that since it is small and portable it may encounter drops while being used, I am just not sure how rugged the unit is with the ultrasound flow detector in side.
