Tektronix entered the medical products field after the company was founded. Initially, Dick Ropiequet worked on 160 series instruments specifically for medical applications for the University of Oregon Medical School. These early instruments were intended to continue the work done by Dr. Tunturi on the nervous system.

1971 proved a stressful year for the company.  Jack Murdock died in an airplane accident, sales dropped 11.6% from $165.2 million to $146 million, and inventory was at an all time high.  In late May of 1971 Howard Vollum suffered a heart attack.  While recovering in the hospital he knew Tektronix could develop even better medical products and they did so with the introduction of the Model 414 portable patient monitor in 1976.  The museum has a 414 monitor on display.

The museum also has a 413 neonatal monitor on display.  The 413 front panel opens up to access the full capability of the instrument.  It could display heart, respiration, and blood pressure/pulse on a three trace display.  Digital readouts could display two temperatures or difference, heart rate, respiration rate, or blood pressure.  We do not have any probes for this monitor.
