Eligibility
Key inclusion criteria
Premature infants with a corrected gestational age of 28-34 weeks, admitted to the Neonatal Intensive and Special Care and treated with nasal CPAP.
Minimum age
28 Weeks
Maximum age
34 Weeks
Gender
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Infants with sepsis, organ failure, necrotizing enterocolitis, seizures, or identified by the clinical team to be too sick to participate in the study will be excluded.
Infants will be excluded if they have congenital heart disease including a haemodynamically significant patent ductus arteriosus (PDA), atrial septal defect (ASD)/persistent foramen ovale (PFO) and/or ventricular septal defect (VSD). Infants will also be excluded if they are treated with fractional inspired oxygen (FiO2) of more than 40%, and/or treated with a PEEP higher than 7 cmH2O, or nasal intermittent mandatory ventilation (nIMV).

Summary
Brief summary
The aim of the study is to determine changes in blood flow in the heart associated with low or high air pressures given with the nasal prong breathing support to the prematurely born infant. Research studies have shown that nasal CPAP can influence the way the blood flows in premature infants.
We want to find out if the CPAP machine affects the function of the heart and the blood flow to the lungs. So that we can learn what is the most appropriate level of CPAP for infants with different types of lung disease that provides respiratory support with least affect on heart function.
