  2. Cervical motion tenderness - Wikipedia

    en.wikipedia.org/wiki/Cervical_motion_tenderness

    PID, Ectopic pregnancy Cervical motion tenderness or cervical excitation is a sign found on a gynecological pelvic examination suggestive of pelvic pathology . Classically, it is present in the setting of pelvic inflammatory disease (PID) or ectopic pregnancy and is of some use to help differentiate PID from appendicitis . [ 1 ]

    en.wikipedia.org/wiki/Montevideo_units

    Units are directly equal to pressure change in mmHg summed over a ten-minute window. It is calculated by internally (not externally) measuring peak uterine pressure amplitude (in mmHg), subtracting the resting tone of the contraction, and adding up the numbers in a 10-minute period. [1]

  4. Bishop score - Wikipedia

    en.wikipedia.org/wiki/Bishop_score

    Bishop score, also Bishop's score or cervix score, is a pre-labor scoring system to assist in predicting whether induction of labor will be required. [1] It has also been used to assess the likelihood of spontaneous preterm delivery. [2]

  5. Ballard Maturational Assessment - Wikipedia

    en.wikipedia.org/wiki/Ballard_Maturational...

    The New Ballard Score allows scores of −1 for the criteria, hence making negative scores possible. The possible scores then range from −10 to 50, the gestational range extending up to 20 weeks. (A simple formula to come directly to the age from the Ballard Score is Age=((2*score)+120)) / 5. Maturity Rating:

  6. Smith predictor - Wikipedia

    To check that this works, a re-arrangement can be made as follows: Here we can see that if the model used in the controller, G ^ ( z ) z − k {\displaystyle {\hat {G}}(z)z^{-k}} , matches the plant G ( z ) z − k {\displaystyle G(z)z^{-k}} perfectly, then the outer and middle feedback loops cancel each other, and the controller generates the ...

  7. Estimated date of delivery - Wikipedia

    en.wikipedia.org/wiki/Estimated_date_of_delivery

    The estimated date of delivery (EDD), also known as expected date of confinement, [1] and estimated due date or simply due date, is a term describing the estimated delivery date for a pregnant woman. [2] Normal pregnancies last between 38 and 42 weeks. [3] Children are delivered on their expected due date about 4% of the time. [4]

    Another approach calculates initial values via the Ziegler–Nichols method, and uses a numerical optimization technique to find better PID coefficients. [28] Other formulas are available to tune the loop according to different performance criteria. Many patented formulas are now embedded within PID tuning software and hardware modules. [29]

  9. Amniotic fluid index - Wikipedia

    en.wikipedia.org/wiki/Amniotic_fluid_index

    [1] AFI is the score (expressed in centimetres ) given to the amount of amniotic fluid seen on ultrasonography of a pregnant uterus . To determine the AFI, doctors may use a four-quadrant technique, [ 2 ] when the deepest, unobstructed, vertical length of each pocket of fluid is measured in each quadrant and then added up to the others, [ 3 ...
