A Fontanometer can be presented as an altered copy of the Schiotz tonometer. This medical system is used for guesstimating the comparative state of intracranial pressure in an children. The standardization and a more accurate value is understood in an easier way only after a much wider series of eases already been studied, and evaluations are carried out on the basis of direct, simultaneous quantification of intraventricular pressures with without the intervention of a manometer.
For the period in-between, in spite of the fact that the explicit quantitative values simply can't be attributed to the present readings, the instrument is proffered as an undemanding and easy clinical method of calculating intracranial pressure in infants without any turning to ventricular on spinal puncture. A Fontanometer is, therefore, designed so when it comes to make non-invasive measurement of ICP in infants with the help of the principle relating to applantation of the fontanelle.
A high frequency response provided with Fontanometers presents a good and helpful display of respiratory and pulse pressure waves. Item or service has been into medical use for significant years. Moreover, the balloon featured with sensor allows the baseline to be investigated by equalizing the pressure below and above the sensor in situ. Above all, the instrument could be sterilized easily by the way of cold aqueous solutions of detergicide (like Cidex) or perhaps by ethylene oxide oil. It is advisory to watch out and not use sodium hypochlorite remedy.
The main specifications found in a Fontanometer include:
Sensor is one among the the important features such as a metal diaphragm inclusive of directly deposited resistive strain gauges. Excitation standardized with regard to the Fontanometer vitiates 5V AC r.m.s - 1VDC. Bridge resistance. Level of sensitivity. Linear pressure range. Compensates temperature range. Temperature co-efficient of zero. Temperature co-efficient of sensitivity. Linearity and hysteresis error. Overpressure. Catheter, made form flexible silicone rubberized. Connector.
The main benefits working in using a Fontanometer lie in its being highly non-invasive while measuring ICP in children. Another important advantage of a Fontanometer is its compatibility with most strain gauge pressure monitors involving the usage of extension lead type EL-1, with right connector, fitted by the consumer. Besides, the Fontanometers furthermore safe for they could be sterilized thus mitigating the prospects of infections.
The Fontanometers have congregated the will need a reliable, continuous, and regular non-insidious monitoring in infants who are usually a chance of developing RICP in addition to those who already the increased emotional stress. Moreover, it contains an electronically inactive implant and can identify proximal shunt malfunction if positioned in line.
The Use of Fontanometers
The regarding Fontanometers, the usual full term neonatal full-term ICP by way of fontanometry has been confirmed to be approximately six.4mmHG, which differs significantly from the common range of neonatal lumbar CSF demands. The use of a Fontanometer allows CSF drainage to conducted on a limited basis while the ICP remains high in spite of the therapy.
A Fontanometer, therefore, aids in continuous monitoring that produces large variety of raw data, which will have to be interpreted carefully.
