Forced ex-and inspiration
Hard inhalation, followed by a fast expiration and a fast, deep inspiration.

In this mode the device measures the following parameters:

• FVC Forced Vital Capacity
• The amount of air, which the patient moves while exhaling as fast and as deep as possible.
• FIVC Forced inspiratory vital capacity
• The volume change of the lung between a maximal expiration to residual volume and a full inspiration to total lung capacity.
• FEV1 Forced Expiratory Volume 1 sec
• The volume of air exhaled during the first 1 seconds.
• FEV1/FVC
• The ratio of FEV1 and the Forced Vital Capacity.
• FEV6Forced Expired Volume 1 sec
• The volume of air exhaled during the first 6 seconds.
• PEF Peak Expiratory Flow rate
• The greatest exhalation flow during forced exhaling.
• FEF25 Forced mid-Expiratory Flow rate
• The calculated flow at 25% of forced exhaling.
• FEF50 Forced mid-Expiratory Flow rate
• The calculated flow at 50% of forced exhaling.

• FEF75 Forced mid-Expiratory Flow rate
• The calculated flow at 75% of forced exhaling.
• MMEF2550 Maximum midexpiratory flow
• This is the average expiratory flow over the middle half of the FVC.
• MMEF2575 Maximum midexpiratory flow
• This is the average expiratory flow over the middle half of the FVC.
• FET Forced Expiratory Time
• The time of forced expiration.
• FIV1 Forced Inspiratory Volume 1 sec
• The amount of air inhaled during the first 1.0 seconds of forced inhalation.
• PIF Peak Inspiratory Flow rate
• The greatest flow during forced inhalation.
• FIF25 Forced inspiratory flow at 25%
• Forced inspiratory flow at 25% of inhaled volume.
• FIF50 Forced inspiratory flow at 50%
• Forced inspiratory flow at 50% of inhaled volume.
• FIF75 Forced inspiratory flow at 75%
• Forced inspiratory flow at 75% of inhaled volume.

Static vital capacity measurement
Vital capacity is the amount of air inhaled after a full exhalation.

In this mode, the device measures the following parameters:

• VC Vital Capacity
• The volume change of the lung between a full inspiration and a maximal expiration.
• IVC Inspiratory Vital Capacity
• Inspiratory vital capacity is the amount of air, which the patient inhales after a full exhalation.
• IC Inspiratory Capacity
• The maximum amount of air a person can expel from the lungs after first filling the lungs to their maximum extent and then expiring to the maximum extent.
• ERV Expiratory Reserve Volume
• Expiratory reserve volume is the largest volume of air a patient is able to expiration from an average relaxed expiratory endpoint.

• TV Tidal Volume
• The breath volume is the average amount of air moved during relaxed breathing cycles.
• TI Inspiratory time
• Resting inspiratory average time
• TE Expiratory time
• Resting expiratory average time
• VE Ventilation at rest
• RR Respiratory rate
• The number of breaths per minute
• TV/TI Tidal Volume / Inspiratory time
• Resting inspiratory average flow
• TE/TI Expiratory time / Inspiratory time
• The ratio of TE and TI

Maximal voluntary ventilation
Maximum amount of air during continuous breathing.

In this mode the device measures the following parameters:

• MVV Maximal Voluntary Ventilation
• he volume of air moved in one minute during maximal voluntary respiration.
