The Active Servo Lung 5000 Adult/Neonatal Breathing Simulator, a powerful new software package, is based completely on LabVIEW, National Instrument's acclaimed instrumentation software. Spontaneous breathing can be simulated with any breath profile, including coughs and active exhalation -- even actual patient recordings. The ASL 5000's modeling parameters are software configured, allowing users to specify precisely the response of any active or passive lung model. (Photo: Dr. Stefan Frembgen)
