2015, Paediatric Respiratory ReviewsCitation Excerpt :He showed that after each breathing movement, which he described as an “engulfment of air”, more gas was visible in the upper airways until it creates a positive pressure in the lungs and thereby causes lung aeration and increase of FRC [18]. The “glossopharyngeal breathing” could not be confirmed by Milner and Vyas who showed that a number of infants generated positive intrathoracic pressure prior to their first breath [19]. Although glossopharyngeal breathing has never been formally rejected as a potential mechanism, it is considered too slow and inefficient to make a substantial contribution to lung gas volumes.
Perinatal Physiology and Principles of Neonatal Resuscitation
2008, Clinical Pediatric Emergency MedicineCitation Excerpt :In most infants, FRC is gradually established in a stepwise fashion over several PPV breaths. However, when PPV is provided without PEEP, in the absence of spontaneous respiratory effort, FRC may not be established especially in surfactant deficient preterm infants [5]. Accumulating evidence indicates that it is important to hold the surfactant-deficient lung open with an adequate PEEP to minimize pulmonary edema and cytokine release and to improve compliance and the response to surfactant [4].
A consideration of neonatal resuscitation

2004, American Journal of Obstetrics and GynecologyCitation Excerpt :Physiologically, there may be a benefit to the land-based experience of giving birth. Scientific evidence suggests that intrathoracic pressure of 200 cm of water occurs by the vaginal squeeze.14,15 The process of squeezing the fetus through the birth canal may act in the same manner as the old-fashioned wringer that was used to remove excess water from wet clothes.
