Mask leak in one-person mask ventilation compared to two-person in newborn infant manikin study

Abstract

Two-person mask ventilation technique reduces mask leak by approximately 50% compared to the standard one-person mask ventilation method. NP mask ventilation has higher mask leak than Laerdal SIB for both single- and two-person technique mask ventilation.

An instructional video enhanced bag-mask ventilation quality during simulated newborn resuscitation

“…All participants watched a five‐min teaching (Video S2), which demonstrated: (a) correct positioning of the head , (b) Two point top hold position during round mask ventilation , (c) correct positioning of an air cushion mask , (d) one‐person versus two‐person mask ventilation technique and (e) mask ventilation guidance by observing adequate chest rise . The two‐person mask ventilation technique was demonstrated according to Tracy et al.…”

“…with one member holding the mask on the upper rim at four points while the third to fifth fingers curled under the mandible to apply jaw thrust, lift the face into the mask, and correct head positioning. The other person stood to the side of the manikin and used the bag . In addition, potential pitfalls of mask ventilation including overextension and flexion of the head , airway obstruction and applied force to achieve an airtight seal were demonstrated.…”

“…Prior to baseline recording participants reviewed images of one‐person and two‐person mask ventilation technique for both facemasks . The pair performed two‐person mask ventilation with one member holding the mask and the other person standing to the side of the manikin and using the bag . Prior to each recording, participants were given time to familiarise themselves with the equipment.…”

“…However, human and technical factors interfere significantly with the effective ventilation of newborn infants . Mask type, finger position and number of resuscitators have been shown to influence quality of PPV . Immediately after birth, newborn infants are supported by healthcare professionals with varying experience and training in neonatal resuscitation, ranging from specialised neonatal healthcare professionals, anaesthesiologists or gynaecologists in smaller community hospitals to midwives assisting births in midwife led hospitals and during home births.…”

“…There may be situations in which two hands will be required to achieve an adequate seal around the face mask. In such situations, the two-person technique is recommended, one person holding the face mask and the other ventilating the patient [28,30,32,86,88]. Re: 5.…”
