Objective:
To identify the changes that occur in the physiological parameters of newborns under oxygen therapy during the collection of arterial blood gases, comparing the moments immediately before, immediately after, and five minutes after the procedure.
Methods:
A longitudinal study, of the before and after research design. The sample was composed of 67 newborns under oxygen therapy that had an arterial puncture for blood gas analysis.
Results:
The group of newborns in an Oxyhood experienced significant alterations (p<0.05) in heart rate, pulse and oxygen saturation. Newborns on mechanical ventilation had alterations in respiratory rate and pulse, while those with nasal CPAP showed no instability in physiological parameters.
Conclusion:
The painful stimulus caused by the collection of blood gases in newborns showed changes in all physiological parameters, however, for such a procedure, the changes were different for each mode of oxygen therapy.
