How do you measure duration of contraction?
Duration is measured from the beginning of one contraction to the end of that contraction. Time the duration of a contraction by starting your timer when a contraction starts and stopping the timer when the contraction ends. Somewhere in the middle, you’ll feel a peak in intensity but wait until all sensation has stopped before you stop the timer.
How do you find the frequency of contractions?
Frequency of contractions – “How far apart are they?” Frequency is based on the time between the start of one contraction and the start of the next contraction. Time the frequency of contractions by noting the time when one contraction starts and the time when the next contraction starts.

How do you calculate contraction strength?
subtract the resting tone from the peak intensity of the contraction. add the 3 contractions together to get the MVUs. Montevideo units are calculated by obtaining the peak uterine pressure amplitude and subtracting the resting tone. Then adding up those numbers generated by each contraction within a 10-minute window.

What determines the strength of a mm contraction?
The higher the recruitment, the stronger the muscle contraction will be. The greater the cross-sectional area of the muscle, the more muscle fibres that can be activated simultaneously.
How is the contraction frequency calculated?
Contraction frequency is calculated from the start of one contraction to the start of the next one. For example, if the first contraction starts at 10 a.m. and the next contraction starts at 10:10 a.m., the contraction frequency is 10 minutes.
