Diathermy: Surgical & Therapeutic Applications

High-frequency currents, apart from their usefulness for therapeutic applications, can also be used in operating rooms for surgical purposes involving cutting and coagulation. The frequency of currents used in surgical diathermy units is in the range of 1-3 MHz, in contrast to much higher frequencies employed in short-wave therapeutic diathermy machines. This frequency is quite high in comparison with that of the 50 Hz mains supply. This is necessary

Modern Medical Diagnostics and Therapeutic Innovations

Non-Invasive Diagnostic Techniques

Non-invasive techniques are crucial for diagnosing various conditions without requiring surgical entry into the body. These methods provide detailed insights into internal structures and functions, aiding in early detection and treatment planning.

  1. X-ray Imaging

    An X-ray is an image registered on a photographic plate of an object exposed to X-rays. This fundamental diagnostic tool is widely used for examining bones, teeth, and certain soft tissues.

  2. Ultrasound Imaging

Biomedical Measurement Techniques: Pressure, Flow, and ECG

Direct Blood Pressure Measurement

This method involves inserting a tube or catheter directly into the blood vessel. The catheter is connected to a blood pressure transducer, which generates a corresponding electrical signal. This method is classified into two types:

  1. Extra-vascular pressure sensor
  2. Intra-vascular pressure sensor

Indirect Blood Pressure Measurement

In this method, external pressure is applied to the artery using an instrument called a sphygmomanometer. There are two main techniques:

  1. Palpatory

Medical Diagnostic Tests: ECG, Glucometer, MRI, EEG, X-Rays, PET, Ultrasound

Electrocardiogram (ECG)

An electrocardiogram is a painless test that records the electrical activity of the heart. You will be asked to lie down while a healthcare provider attaches small electrodes to your chest. These electrodes are connected by wires to a machine that turns the heart’s electrical signals into wavy lines, which are printed on paper.

These signals show three parameters: P wave, QRS complex, and ST segment. The size of these parameters and the distance between them can reflect:

  • Damage
