Forced Maneuvers

Similar to spirometry in cooperative humans, Buxco's Forced Maneuvers systems provide comprehensive pulmonary function data for preclinical applications. The systems – available for mouse, rat/guinea pig, and larger subjects – are highly-automated and include all necessary hardware and software.

For the FRC maneuver, subjects must be spontaneously-breathing. For other maneuvers, subjects may be ventilated (ventilator included) or spontaneously-breathing. Subjects are anesthetized.

Available maneuvers

• Resistance and Dynamic Compliance
• Boyle's Law FRC
• Fast Flow Volume
• Quasistatic Pressure Volume
• DLCO and Multi-breath DLCO (except mouse)

Features

• Preferred system for COPD research
• Software-driven system, highly-automated
• Fast-response valving, low dead space
• Complete a series of maneuvers in just minutes
• Determine FRC and other lung capacities
• Software reports FEV(x), FEF(x) and many other values
• Ability to study small rodents - even mice
• Direct measurement of lung resistance and dynamic compliance
• View results immediately, use overlays to compare repeated maneuvers
