Efficacy of Non Invasive Biphasic Cuirass Ventilation (BCV)
in Neonatal Piglets Comparison with Conventional

The need for prolonged IPPVdespite successful surfactant treatment
is a major risk factor for BPDCan
NEGATIVE PRESSURE VENTILATION
be a successful NON INVASIVE alternative mode of ventilation for newborns at risk for BPD
DÉJÀ VU ?DÉJÀ VU ?1970197019501950 PAST :
Effective ventilation of surfactant deficient lungs required levels of inspiratory pressure beyond the capacity of
negative pressure respirators incubator
PRESENT : Surfactant treatment restores normal lung compliance Continued prolonged ventilatory support relates to poor respiratory drive (apnea of prematurity ) BCV is a modified efficient form of negative pressure
ventilation successful in adult and children with respiratory failure due to neuromotor dysfunction

Purpose of this study:
investigate the efficiency of BCV in an neonatal animal model
Purpose of this study:
investigate the efficiency of BCV in an neonatal animal model
• Can Biphasic Cuirass ventilation successfully ventilated apneic newborn
• Does the cuirass positive pressure component used during expiration :– Enhanced its efficiency– Can this “mild” compression adversely affect FRC
in newborn who have a very compliant chest wall
• What is the optimal I:E ratio in relation to efficiency
