What defines open glottis pushing during labor?

Open glottis pushing during labor is characterized by the technique of pushing for a specific duration—typically between 6 to 8 seconds—repeated for several cycles, commonly four times. This method contrasts with closed glottis pushing, where women may hold their breath or vocalize, resulting in increased intrathoracic pressure.

Using an open glottis allows for more effective expiration and can help reduce the risk of pelvic floor trauma, as well as allow for better oxygenation for both the mother and fetus during the pushing phase of labor. This technique emphasizes natural physiological responses and promotes a more controlled and less straining approach to birthing. It encourages the laboring person to maintain vocalization or to exhale during pushing, which contributes to better overall comfort and safety.

In essence, the definition ties closely to the rhythm and duration of pushing efforts, emphasizing the benefit of prolonged periods of the pushing cycle following natural physiologic principles.
