Answer:
The CPT code for second trimester obstetrical ultrasound with a fetal anatomical evaluation to obtain fetal heartbeat and fetus’s position is CPT code 76811.
Explanation:
According to the Society for Maternal-Fetal Medicine, the CPT code 76811 ultrasound is a pregnant uterus real-time ultrasound complete with image documentation performed to diagnose fetal anomalies. It is done during the second trimester of pregnancy with various indications like twin, triplet, or quadruplet pregnancy; suspected fetal any genetic or anatomic anomalies; maternal gestational diabetes, obesity etc. Fetal anatomical structures like abdomen, chest (heart), extremities, head, face and neck, spine, and position of the fetus are examined under this ultrasound. This ultrasound provides fetal 4-chamber heart view with heart activities to identify any fetal or congenital heart defects
Answer:
3432 Hz.
Explanation:
The resonant frequency of the canal can be calculated as follows:
f = v/ 4l
Here, f is frequency, v is velocity of sound and l is the pipe length.
l = 2.5 cm = 0.025m and v = 343.2m/s.
Put these values to find the resonant frequency
f = 343.2 / 4 * 0.025.
f = 3432 Hz.
Thus, the answer is 3432 Hz.
