Aqua gel, also known as ultrasound gel or coupling gel, is a specialized gel used as a medium to transmit ultrasound waves between the transducer probe and the patient's skin during various medical imaging procedures such as ultrasound imaging (USG), cardiotocography (CTG), and fetal Doppler monitoring. Here's more information about aqua gel for USG, CTG, and fetal Doppler: Purpose: The primary purpose of aqua gel is to serve as a conductive medium that facilitates the transmission of ultrasound waves between the ultrasound probe and the patient's skin. This allows for the production of high-quality ultrasound images and accurate Doppler signals during imaging and monitoring procedures. Composition: Aqua gel is typically water-based and contains ingredients that provide viscosity, lubrication, and acoustic coupling properties. Common ingredients may include water, glycerin, propylene glycol, cellulose derivatives, preservatives, and sometimes colorants or fragrances. Conductivity: Aqua gel is formulated to have optimal acoustic properties, ensuring efficient transmission of ultrasound waves while minimizing air pockets or impedance that could degrade image quality or Doppler signals. High-quality aqua gel ensures clear visualization of anatomical structures and accurate assessment of blood flow. Viscosity: The gel's viscosity is designed to be suitable for easy application and spreadability on the skin without dripping or running. It should provide sufficient contact between the ultrasound probe and the skin surface while allowing for smooth movement during scanning. Non-Irritating: Aqua gel is typically formulated to be hypoallergenic, non-greasy, and non-irritating to the skin. It should be gentle and comfortable for patients, even those with sensitive skin, to ensure a positive imaging or monitoring experience. Compatibility: Aqua gel is compatible with a wide range of ultrasound transducers and probes used in various medical imaging applications, including abdominal, obstetric, vascular, cardiac, and musculoskeletal ultrasound examinations. It is suitable for use with both standard and specialized ultrasound equipment. Application: Before applying aqua gel, the skin should be cleaned to remove any oils, lotions, or dirt that may interfere with ultrasound transmission. A generous amount of gel is then applied to the skin at the imaging or monitoring site before placing the ultrasound probe or Doppler transducer. Hygiene: Aqua gel should be stored in a clean and dry environment to prevent contamination. Single-use disposable packets or bottles with dispensing caps are commonly used to maintain hygiene and prevent cross-contamination between patients.
