DEFIBRILLATOR ELECTRODES

                    DEFIBRILLATOR ELECTRODES:
  • Generally three types of Electrodes are used:
1)                  External Electrodes: Used for transthoracic stimulation. It consists of metal discs about 3-5 cm in diameter and areattached to highly insulated handles. Most of the conventional electrode systems are circular, alittle concave with insulated back-side.Electrode gels are usually employed to reducecontact impedance of the interface.


2)                  Internal Electrodes:Used for direct cardiac stimulation. For internal defibrillation when thechest is open, spoon-shaped electrodes are used.They are made-up of polished, surgical-quality stainless steel. These paddles are overmolded with durable plastic.
 

3)                  Disposable Electrodes:Used externally on chest wall. Pre-gelled and self- adhesive electrodes have been used for Automatic External Defibrillator.

MICROPROCESSOR BASED VENTILATOR

Microprocessor based Ventilator   Figure shows the block diagram of microprocessor controlled ventilator.(given below). It consists of two inter-connected systems: The Pneumatic flow system and an Electronic control system. The pneumatic flow system enables the flow of gas through the ventilator. Oxygen and medical grade air enter the ventilator at 3.5 bar (50 psi) pressure. These gasses enter the air/oxygen mixer where they combine and gasses then enter a large reservoir tank. An electronically controlled flow valve proportions the gas flow from the reservoir tank to the patient breathing circuit.   As the gasses leave the ventilator, they pass by an oxygen analyzer, a safety ambient air inlet valve and a back-up mechanical over pressure valve. The microprocessor controls each valve to deliver the desired inspiratory air and oxygen flows for mandatory and spontaneous ventilation. The electronic control system may use one or...

BED SIDE MONITOR/ MULTI PARA MONITOR

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...
