Automatic External Defibrillator / Advisory External Defibrillator (AED):


Automatic External Defibrillator / Advisory External Defibrillator (AED):

  • Automatic or Advisory external defibrillators (AEDs) are capable of accurately analyzing the ECG and making reliable shock decisions.

  • AED are designed to detect ventricular fibrillation then deliver (automatic) or recommend (advisory) an appropriate high energy defibrillating shock.

  • AED require self-adhesive electrodes instead of hand-held paddles.

  • A critical factor in the safety and performance of an automatic external defibrillator is the ability of the device to accurately assess the patient’s heart and make an appropriate therapy decision.

  • The defibrillator performs this evaluation by sensing electrical signals from the patient’s heart via electrodes and using a computerized algorithm to interpret the electrical signals.
  • The algorithmused in the modern defibrillators looks at four key indicators to determine whether a rhythm is shockable or non-shockable. These four indicators are heart rate, conduction, stability and amplitude.

  • It is small, light and virtually maintenance-free.The device is powered by a long-life disposable lithium battery with enough capacity for 75 discharges.

  •  It uses a low energy biphasic waveform.

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...

DC defibrillator principle & defibrillator.

                          DC DEFIBRILLATOR:   In almost all present-day DC defibrillators, an energy storage capacitor is charged at a relatively slow rate (seconds) from the AC line by means of a step-up transformer and rectifier arrangement or from a battery and a DC to DC converter arrangement the energy stored in the capacitor is then delivered at relatively rapid rate (millisecond) to the chest of the patient.             The basic circuit diagram of a DC defibrillator is shown in Figure. A variable auto-transformer T1 forms the primary of a high voltage transformer T2. The output voltage of the transformer is rectified by a diode rectifier and is connected to a vacuum type high voltage change-over switch. In position A, the switch is connected to on...

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...
