Pulse oximeter method as an indicator of blood perfusion in neonate patients / Naszariah Mohd Noor

Blood gas measurements normally provide critical information on oxygenation, ventilation and acid-base status. In critically ill neonates, where peripheral perfusion may drop below the minimums required for tissue oxygenation and cellular respiration, the risk associated with rapid changes in oxy...
