- 中文摘要: 本文描述以微處理機為基礎並配合數位訊號處理技術所完成之床邊監視器設計原理及其功能。此床邊監視器以Z80A微處理機作為中央處理單元。能夠同時監視心電圖波形,心跳速率、血壓、呼吸及溫度。並具有語音警告,心室早期收縮診斷及心律不整時自動記錄心電圖波形等特殊功能。這些功能可以藉助系統軟體及診斷程式的改良,配合少許的硬體修改而增強其功能,故而具有相當之發展潛力。
- 英文摘要: In this article the designing principles and functions of a microprocessor-based bedside monitor alongwith the digital signal processing techniques are described. This bedside monitor based on a Z-80A CPU hasthe capabilities of monitoring the electrocardiograph (ECG) waveform, heart rate, blood pressure, reSpiTa-tion rate, and temperature of patients. In addition,it also provides the special functions of speech alarm,ventricular premature contraction (VPC) diagnosis and auto-recording of abnormal ECG waveforms whenarrhythmia are detected. These functions and capabilities can be easily improved by modifying the systemcontrol software or diagnosis programs accompanied with a little change in hardware circuits.
