MH CUSTOM DESIGN & MFG

Pulmonary Waveform Generator (PWG) systems, designed and manufactured by MH Custom Design & Mfg. L.C., have long been used as the industry standard to test the accuracy of spirometers and peak flow meters. Using state-of-the-art technology patented by MHC, PWG systems are also being used to measure the work-of-breathing through endotracheal tubes, their adapters and numerous other pulmonary devices. PWG systems are computer-controlled, servomotor-driven air syringes, which can deliver any computer-stored pulmonary waveform file within system specifications (0 to 12 liters volume, 0 to 20 liters/second flow). PWG systems incorporate user-friendly software with precise delivery of all ATS Standard Waveforms and user-defined waveforms (constant flow, exponentially-shaped flow and custom flow).
