In medical cables,especially coil cables,AED cable and doppler cord are the two main forms custom doppler cord for doppler probe, 2Mhz to 8Mhz is the main frequency in Fetal Doppler And Vascular Doppler Probe . higher Frenquency for more peripheral the detection will be.Choose the right doppler cord for your doppler probe,you will get more accurate detection.With the correct matchable probes, Many dopplers have the ability to assess fetal heartbeats and what gestation periods or will you be assessing vascular blood flow.(in this sense,it is a fetal doppler and vascular doppler at the same time)
How To Choose A Right Probe For Doppler ?
Doppler cord is not equal to doppler probe,ususally a doppler probe compose a detector and a suitable cord whose frequency is suitable for the detector. As the dectors are usually 3-8 MHZ (≥3MHZ is called High Frequency)),it is meanningless to mention High Frequency here. Vascular and obstetrical probes work on different ultrasound formats and it is highly improbable that you will be able to effectively assess the opposite sounds with accuracy to which the probe is designed.
Obstetrical Applications.
With hand held dopplers, all probes less than a 3MHz will be used for obstetrical application.
2MHz fetal doppler probe– This is a later term obstetrical probe and will attain deeper penetration. This is often the choice for anything after 21 weeks gestation. It is also often available in a waterproof version for tub labor or assessments in the shower.
