The labor force is like a bowel movement but not exactly like a bowel movement. Labor force is generally in the second stage of labor after the opening of the mouth, let the mother feet stirrups on the delivery bed, both hands holding the handles of the delivery bed, contractions deep inhalation and then hold the breath, and then like defecation-like downward pressure to increase abdominal pressure, and between contractions to let the mother free breathing and the whole body muscle relaxation, and then contractions do the same hold the breath to accelerate the progress of labor. Bowel pushing is a simple increase in abdominal pressure and may be combined with anal sphincter contraction activity. Labor pushing requires more skill than bowel pushing, and is best combined with breathing. It is recommended that the mother keep a good mindset during labor, not to be nervous, and can do more deep breathing movements to ease the tension, and according to the guidance of the midwife to cooperate with the force, and pay attention to the preservation of energy before the birth, it is best not to yell or overwork, so as not to affect their own labor.
