Description of intervention(s) / exposure
This study will explore newborn essential observations such heart and breathing rates, blood pressure, temperature and oxygen levels continuously for up to 6 hours per day for the duration of admission. This will be undertaken to determine the ranges and whether there are differences in each gestational age group for each of these essential (vital) signs.

Outcomes
Primary outcome [1] 306157 0

Primary outcome [2] 306201 0
Temperature as assessed by infrared thermometer
Timepoint [2] 306201 0
From 2 hours post birth then at the beginning and end of monitoring session. One monitoring period per participant.
Primary outcome [3] 306202 0
Blood pressure as assessed by automated digital sphygmomanometer
Timepoint [3] 306202 0
From 2 hours post birth then at the beginning and end of monitoring period. One monitoring period per participant.
Secondary outcome [1] 347801 0
Composite secondary outcome: vital signs during times of feeding, sleeping, awake and alert and crying.

Researcher will ask parents how their baby was during the study to provide context to any variation in vital sign ranges. For example, an increased heart rate may be due to the newborn crying.
Timepoint [1] 347801 0
From 2 hours post birth during monitoring session. One monitoring period per participant.

Statistical methods / analysis
No published studies have continuously monitored biophysical parameters of well newborns over a continuous period of any length of time, which makes calculating a sample size difficult.

To test this hypothesis we are going to conduct an interim analysis of data once 10 newborns per gestational age group have been recruited (30 newborns in total) to inform us of the total sample size required to observe a clinically significant difference between at least one gestational age group.

Parametric and non-parametric will be used to analyse data.

Summary
Brief summary
This is an observational study looking at well newborn babies’ essential observations such heart rate, breathing (respiratory) rate, blood pressure, temperature and oxygen levels (saturations) to determine the ranges for each of these essential (vital) signs. Very few studies have measured these essential observations for any length of time and many of the ranges have been adapted from paediatric studies or intermittent observations. At the present time, it is unknown whether there are differences in ranges between those babies born late preterm (greater than 34 weeks) compared to those born at term (greater than 37 weeks) or how behaviours such as sleeping, feeding or crying influence these observations as these may contribute to the early signs of deterioration. Understanding if there are differences in these essential observations is important to inform early warning observation tools and the subsequent care that babies may need.

This study will be conducted in the postnatal ward and special care nursery at the Royal Brisbane and Women’s Hospital. This study will monitor a baby’s essential observations during normal activities such as cuddling, feeding and sleeping for periods of up to 6 hours each day during hospital stay, in addition to the routine monitoring of essential observations currently undertaken. Findings will potentially inform newborn care practices in Australia and overseas and reduce unnecessary separation of babies from their mothers as a result of the baby being transferred to a nursery for closer monitoring.
