RESMON PRO FULL a complete and in-depth functional assessment of the human respiratory system.
Developed and manufactured by:
Distributed by:
RESMON PRO FULL is simple and easy to be used by both patients and physicians for the diagnosis and evaluation of pulmonary diseases. The forced oscillation technique (FOT) is a noninvasive way to measure the mechanical properties of the lung and airways. It is based on the assessment of the response of the respiratory system to small pressure stimuli applied to the airway opening during normal breathing. FOT provides information about the resistance and the reactance of respiratory system.
After few seconds of spontaneous breathing, it allows, in addition to standard breathing pattern index, to identify:
RESMON PRO FULL is also an essential diagnostic tool when spirometry cannot be performed as for:
• the detection of expiratory flow limitation using the ∆Xrs index ; • the assessment of the degree level of airway obstruction; • the evaluation of bronchial reversibility .
• • • •
children; elderly; subjects with neuromuscular diseases; uncollaborative people.
Moreover, thanks to its versatility, it is an ideal tool for research studies.
Built-in reference values for normality and drugs response.

PEDIATRIC APPLICATIONS
ADJUSTABLE SMART SUPPORT
80° Total dead space and load make the device compliant with international guidelines for pediatric applications (see Technical Data).
360°
INTERNAL DATABASE
RESMON PRO FULL is provided with several built-in measurement protocols:
The internal database allows to easily store and retrieve the tests.
MULTI USER ACCESS classical pseudo-random noise (5-37 Hz)
within-breath single new within-breath multiple frequency (5, 6, 8, 10 Hz) frequency (5+11+19 Hz)
Each user can have his own protocol settings.
RAW DATA ACCESS Easy export of measurement tracings for customized post processing.
