PC Spirometer ProSpiro N
The ProSpiro N enables essential pulmonary function tests to be performed. Requiring no external power supply, the device can easily be used on the go with a laptop.
The database is integrated into our DDC (Digital Diagnostic Center) software, allowing all key examinations to be viewed at a glance.

Measurement Modes
Forced Expiration and Inspiration
The patient performs a maximal inhalation, followed by a maximal exhalation at maximum effort and speed.
In this operating mode, the device determines the following parameters:
FVC Forced Vital Capacity
The total volume of air exhaled with maximum effort after full inhalation.
FIVC Forced inspiratory vital capacity
The volume of air inhaled with maximum effort after complete exhalation.
FEV1 Forced Expiratory Volume 1 sec
The volume of air exhaled during the first second of forced expiration.
FEV1/FVC
Ratio of FEV1 to Forced Vital Capacity
FEV6 Forced Expired Volume 1 sec
The volume of air exhaled during the first 6 seconds of forced expiration.
PEF Peak Expiratory Flow rate
The maximum flow rate achieved during forced expiration.
FEF25 Forced mid-Expiratory Flow rate
Expiratory flow rate at 25% of FVC
FEF50 Forced mid-Expiratory Flow rate
Expiratory flow rate at 50% of FVC.
FEF75 Forced mid-Expiratory Flow rate
Expiratory flow rate at 75% of FVC.
MMEF2550 Maximum midexpiratory flow
Mean flow rate calculated over the middle 25–50% portion of forced expiration.
MMEF2575 Maximum midexpiratory flow
Mean flow rate calculated over the middle half (25–75%) of forced expiration.
FET Forced Expiratory Time
Total duration of forced expiration.
FIV1 Forced Inspiratory Volume 1 sec
Volume of air inhaled during the first second of forced inspiration.
PIF Peak Inspiratory Flow rate
Maximum flow rate achieved during forced inspiration.
FIF25 Forced inspiratory flow at 25%
Inspiratory flow rate at 25% of inspiratory volume.
FIF50 Forced inspiratory flow at 50%
Inspiratory flow rate at 50% of inspiratory volume.
FIF75 Forced inspiratory flow at 75%
Inspiratory flow rate at 75% of inspiratory volume.
EV
Static Vital Capacity
The patient performs a maximal exhalation, followed by a slow, continuous, and maximal inhalation.
In this operating mode, the device determines the following parameters:
VC Vital Capacity
The maximum volume of air exhaled after maximal inhalation.
IVC Inspiratory Vital Capacity
The volume of air inhaled from maximum exhalation to full inhalation.
IC Inspiratory Capacity
The maximum volume of air that can be inhaled after normal resting exhalation.
ERV Expiratory Reserve Volume
The maximum volume of additional air that can be exhaled after normal resting exhalation.
TV Tidal Volume
Average volume of air inspired and expired during resting breathing.
TI Inspiratory time
Average duration of resting inspiration.
TE Expiratory time
Average duration of resting expiration.
VE Ventilation at rest
The total volume of air inhaled and exhaled per minute at rest.
RR Respiratory rate
Number of breaths per minute.
TV/TI Tidal Volume / Inspiratory time
Mean resting inspiratory flow rate.
TE/TI Expiratory time / Inspiratory time
Ratio of expiratory time to inspiratory time.
Maximum Voluntary Ventilation (MVV)
The patient inhales and exhales maximally and continuously over a set period.
In this operating mode, the system determines the following parameters:
MVV – Maximum Voluntary Ventilation
Total volume of air exhaled during maximal voluntary breathing, extrapolated to one minute.
A PCS-3000 calibration syringe (3,000 ml) is recommended for daily calibration.
