1.	What is the interval of uterine contractions in a normal patient in spontaneous active labour?(a) 1 to 3 minutes(b) 3 to 5 minutes(c) 5 to 7 minutes(d) 7 to 9 minutesI had been asked this question in an interview.Enquiry is from Ear Oximeter topic in chapter Oximeters of Biomedical Instrumentation
Answer» The correct answer is (c) 5 to 7 minutes The best explanation: During labour, the uterus muscle starts CONTRACTIONS of increasing intensity in a bid to EXPEL out the child. The intrauterine pressure can reach values of 150 mmHg or more during the EXPULSION period. However, a normal patient in spontaneous active labour will demonstrate UTERINE contractions occurring at intervals of three to five minutes, with a duration of 30 to 70 s and a peak intensity of 50 to 75 mmHg.
