Bed side Monitor/ Multi-para Monitor: The Bed side monitoring system is designed to display an electrocardiogram, heart rate with high and low alarms, pulse rate, dynamic pressure or other waveforms received from external preamplifiers. The system basically consists of three circuit blocks: Preamplifier section, Logic boards and Display part. Various amplified signals are carried to a multiplexer and then to an analog-to-digital converter, included in the logic board. The central processing unit along with memory gives X and Y output for the CRT display. The character generator output is mixed with the Y output for the CRT display. The alarm settings, selection switches for different parameters and the defibrillator synchronization system communicate with the CPU. The alarm signals are also initiated under its control. The memory comprises 5K bytes ROM and 3.25K bytes RAM with 256 samples of ECG It basically co...
