Labor Watch
Contractions – is a rhythmic tightening of the musculature of the upper uterine segment that begins
mildly and becomes very strong late in labor
The duration of the uterine contraction is the time from the beginning of one contraction to the end of
that same contraction
During labor, the duration of the contractions will start out short (25 to 35 seconds long) and ultimately
get to 70 – 90 seconds long.
Real contractions follow a consistent pattern, while Braxton-Hicks contractions vary in duration and
frequency.
FREQUENCY
The frequency of the contractions is measured from the beginning of one contraction to the beginning
of the very next. This not only includes the duration of one contraction, but also the rest period between
the two. So if you have a contraction at 8 pm and it lasts for 60 seconds, and then you have another
contraction at 8:15 pm, the contractions have a duration of 60 seconds and a frequency of 15 minutes.
INTENSITY
The intensity of the contractions also changes as labor progresses. Early labor contractions are often
described as mild menstrual cramps. Contractions in later labor, have been described by some stand-up
comedians as feeling like your lower lip was stretched up over your head! While this analogy is
humorous, it is true that with normal labor, the intensity of the contractions does increase, and this is a
good sign that labor is progressing well.
INTENSITY
Mild - the uterus is contracting but does not become more than minimally tense (tip of the
nose)
Moderate - the uterus feels firm (chin)
Strong - the contraction is so intense that the uterus feels as hard as wood at the peek of
contraction (forehead)
