SpiroAir volumetric pulmonary function testing system

Beside spirometry and lung volumes measurement by Helium dilution, several options can be added in the SpiroAir to have a full pulmonary function testing equipment in your lab.

Lung diffusion capacity:

The SpiroAir offers 3 possibilities of lung diffusion capacity measurement (DLCO):

• Traditional Single breath DLCO with Helium tracer gas, using exhalation bag.
• Single breath double diffusion of CO and NO (DLCO-NO) with Helium tracer gas, allowing measurement of membrane diffusion (Dm) and capillary blood volume (Vc).
• Rebreathing DLCO with Helium tracer gas, using rebreathing bag.

For single breath technique, you can choose the method to inhale the mixture:

• the fastest and most economical: through a demand valve.
• the most physiological, especially for patient with less cooperation: through an inhalation bag.

Bronchoprovocation and Special Resistance Testing:

• Provo 4 Provocation System: automated, software controlled, accurate and safe bronchial provocation testing.
• RINT: resistance measurement using flow interruption technique. Ideal for children.
• NEP (negative expiratory pressure): alternative method to detect and quantify expiratory flow limitation, which does not require performance of forced expiratory efforts nor a body plethysmography test.

Respiratory Mechanics Testing:

• MIP – MEP (maximum inspiratory and maximum expiratory pressure): indicator of respiratory muscle strength.
• SNIP: maximal nasal inspiratory pressure using a nasal cannula. A non-invasive indicator of diaphragmatic muscle fatigue.
• P0.1: inspiratory occlusion pressure at 0.1 seconds, for respiratory muscle drive evaluation.
• Static and dynamic compliance and resistance: measured by intra-esophageal balloon catheters.
