ECG/respiration monitor calibrator

This paper describes an ECG/Respiration monitor calibrator used by the Biomedical Staff to check such units quickly, inexpensively and accurately. The calibrator can be constructed by the Biomedical Engineering Staff in one day for a parts cost of less than fifty dollars. Once the calibrator is connected to the patient cable of an ECG/Respiration monitor, the calibrator will generate concurrently a calibrated rate and amplitude ECG-pulse and respiration waveform.
