Abstract

The objective of the present work was to design Doppler sensors and harnesses for monitoring in real time the cardiac stroke volume and output, the cerebral flow volume and resistance and the lower limb arterial flow and resistance changes. For the middle cerebral artery investigation we used a 2-MHz transcranial pulsed wave (PW) Doppler probe (commercial probe) mounted on a rotula, fixed on the horizontal branch of a headset designed like an audio headset. The arch of the headset passed over the top of the skull. For the common carotid investigation, a 4-MHz continuous-wave (CW) or PW flat Doppler probe was inserted in a circular silicone support of 5-cm diameter and 0.6-cm thickness. This soft support could adapt to the irregular surface of the neck, and the silicone material, which is fairly adhesive to the skin, made the system stable. The transducers were preoriented at 45 degrees from the support, which provided an acceptable orientation of the Doppler beam. The aortic Doppler harness consisted of a 2-MHz PW Doppler probe, mounted on a rotula fixed on a plastic rigid support 7 x 1.5 cm2 in area (parallel to the sternum) whose length could be changed (4-7 cm) to localize the rotula and its sensor on the suprasternal area. ...Continue Reading

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
