02 airway support
when does transient tachypnoea of the newborn present?
within the fist few hours of life
what are the risk factors of meconium aspiration?
past dates
maternal diabetes
maternal hypertension
difficult labour
what are the symptoms of meconium aspiration?
cyanosis increased work of breathing grunting apnoea floppiness
what is the management for meconium aspiration?
suction below cord
airways support - intubation and ventilation

placental problem long, difficult delivery umbilical cord prolapse infection neonatal airway problem neonatal anaemia
what are the 2 stages of birth asphyxia?
1st;
- within minutes without oxygen
- cell damage occurs with lack of blood flow and oxygen
2nd;
- re-perfusion injury
- can last days/weeks
- toxins are release from damaged cells
