Q
Internal Monitor
A
When a higher quality signal is desired it may be necessary to place in internal monitor. Conditions where this may occur include obese patients, premature fetuses, or when there is excessive maternal or fetal movement. The internal monitor consists of a spiral electrode that is gently screwed superficially into the fetal scalp. The electrical signal is sent to the console where a signal processor converts the R-R interval of the fetal ECG to a fetal heart rate and displays it as a tracing in beats per minute.
