Assessment of Cranial Blood Volume Changes Using Non-Invasive (BIA) Technique

Publication date: Available online 9 July 2016 Source:Perspectives in Science Author(s): Kashif Javed, Bharat Bhushan Sharma, Munna Khan Bioelectrical impedance analysis (BIA) is a extensively technique used for estimating body composition. It is simple, rapid, non-invasive, fast and cheap method to characterize any matter. Unlike various complicated methods, bio-impedance measurement technique is simple, less time consuming and non-invasive method for various applications including medicine, biotechnology. However, despite of intensive research in this field from more than six decades, only a few applications have been established. This paper presents a novel approach towards the development of Bioelectrical Impedance Analysis technique as a future health care technology. Electrical impedance plethysmography (EIP) is also extremely valuable technique for prospect use in hospital (ICU). The system consists of BIA analyzer and electrical components. The system is based on the principle that accurate percentage change occurs in the cranial impedance range measured on the human subject's scalp due to increase or decrease in cranial blood volume. Measurement of impedance was performed on fifteen healthy subjects of different age group to establish a baseline. Measurement of Cranial Impedance (CI)were performed using multi-frequency current in the 50-200 KHz frequency group using four specially designed electrodes placed on human subject's scalp. Cranial blood volume suc...
