Redefining Accuracy In High Definition HDpft™ 4000 High Definition All-Digital Pulmonary Function Plethysmograph HDpft™ 4000 combines the latest testing capabilities and exclusive High Definition accuracy in an innovative architecture designed to increase productivity and improve the clinical yield of pulmonary function testing. nSight™ 5 software for HDpft simplifies testing processes, shortens procedure time, automates quality assurance, and delivers flexible real-time trending and instant formattable reporting. Redefining Accuracy – Diagnostic Confidence HDpft 4000’s exclusive Single-Breath, linked maneuver delivers Diffusing Capacity (2 methods offered), Total Lung Capacity, Functional Residual Capacity, and Lung Volume results in a single 15 second examination sequence. Whole body plethysmography offers “gold standard” Lung Volume determination and Airways Resistance in seconds. High Definition accuracy in every testing process ensures the confidence you need, even when testing your most challenging patients. Redefining Accuracy – Improving Outcomes iFlow™ advanced flow sensor technology delivers the industry’s best resolution, ensuring flow & volume measuring accuracy and reproducibility at 300% more than the industry standard. iFlow’s superior accuracy permits you to identify smaller changes in lung function sooner, dramatically enhancing diagnostic precision, treatment planning decisions, and monitoring value even with the most subtle longitudinal changes in lung function. We continue redefining accuracy so you can improve patient outcomes, more efficiently and more profitably. Redefining Accuracy – Clinical Outcomes “If the variability of the results can be diminished and the measurement accuracy can be improved, the range of the normal values for populations can be narrowed and abnormalities more easily detected.” 2 Inspiring Respiratory Health

Redefining Accuracy — Clinically Proven Technology Technical Specifications • MicroGas-HD™ Analyzer. Clinically proven at two times the industry standard in accuracy and precision without the need for pre-test calibration. Real-time display and exclusive High Definition retrospective data analysis reduces the need for repeat exams. This fast response analyzer is used for both the Diffusion Capacity (DLCO) test and the optional Nitrogen Washout lung volume test. Tests Performed: Spirometry (FVC, MVV, SVC) (36 parameters), Lung Volumes (Plethysmography) (21 parameters), Diffusing Capacity (Single-Breath...
