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
Heart rate and respiratory rate as assessed by Pulse oximetry
Timepoint [1] 306157 0
From 2 hours post birth then at the beginning and end of monitoring session. One monitoring period per participant.
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.
