NDD Spirometer Q&A

Why does the EasyOne need not be calibrated?

The following two main characteristics make the instrument calibration free: a) The EasyOne spirometer determines flow by measuring the flight time of ultrasonic pulses. The time measurement is performed digitally using a precision quartz clock. b) The transducers that are used for this time measurement are mounted outside of the flow tube. Changing the flow tube does not change the characteristics of the transducers. In addition, the ultrasonic flow measurement is inherently independent of temperature, humidity, pressure, and gas composition. While the EasyOne does not require calibration, it is important to note that the American Thoracic Society, NIOSH/OSHA, and others recommend that the accuracy of the spirometer be verified on a regular basis. This verification is easily done using the ndd 3-liter syringe. Do you need to use a filter?

Most spirometers use some sort of flow sensor that is in direct contact with the exhaled breath. Filters are used to reduce the contamination of this sensor. The EasyOne spirometer, on the other hand, measures the flow in a completely open tube using ultrasonic transit times. Cross-contamination can be completely avoided by changing the flow tube (the Spirette) between patients.

How accurately does the EasyOne measure in low flow situations, such as testing children?

There is no problem using the EasyOne spirometer for children: The ultrasonic flow measurement is very sensitive at low flows (flow resolution is below 10 ml/s) and the flow tube exhibits an extremely low flow resistance.

Is the spirette suiotable for children?

The spirette flow tube's special ergonomical design easily accommodates a child's lips and teeth. The flow tube can be used for both adults and children down to the age of five years.

Can the predicted normals be changed?

Several predicted normal values can be selected from the Setup menu. An overview of the predicted normals is available on the EasyOne Documentation page. We appreciate your feedback if important predicted normal values are missing.

What is the internal memory size?

EasyOne automatically stores more than 700 test sessions (patient data, test results, and curves). These measurements can be selected and viewed at any time. They can also be printed individually or in ranges upon demand. Using the PC software EasyWare the measurements can be downloaded to a PC database.

Why is the EasyOne not equipped with rechargeable batteries?

The power consumption of EasyOne is very low. With two AA alkaline batteries approximately 400 measurements can be executed. Rechargeable batteries would make the device less reliable and more expensive.

Are other Sprometers easier to operate?

For the following reasons EasyOne has low operating costs: a) Due to its operational principle EasyOne does not require re-calibration. b) There is no need to buy a calibration syringe, unless you want to verify accuracy. c) You do not need to buy filters. d) The flow sensor is robust by design. e) No expensive and sensitive parts can be contaminated. f) There is no maintenance required.

Can masks be used with the EasyOne?

Yes you can use masks. There are 2 possibilities: A) commonly available masks with 22mm joint flange; cut the mouth piece part of the spirette as shown and insert the modified spirette. B) Laerdal silicone masks allow the use w/o any modification of the spirette. Fold the mouthpiece part of the spirette and insert the spirette (mouthpiece first from the front) through the mask opening. This can be important whenever you need to use unmodified original parts (Studies etc.).
