This guideline describes the technique for priming and calibrating an arterial line using the Kids Kit™ Closed Blood Sampling System from Medex.
This Guideline is applicable to all registered nursing staff / clinicians working in neonatal units in Greater Glasgow and Clyde who have had the appropriate training to perform this procedure.
An indwelling arterial line may be used when:
The WoS Neonatal MCN recommends the use of a closed circuit system to reduce the risk of infection secondary to repeated sampling from indwelling arterial lines.
A sterile technique should be used when priming the system and attaching to the patient. The intravenous fluid prescription chart should be checked by 2 nurses or a nurse and doctor against the baby’s ID band to confirm that the correct solution and rate has been prescribed.
To zero the system – open zero 3-way tap to atmosphere and off to patient. Press zero calibration button on monitor until zero complete is acknowledged (-1 to +1 mmHg). The transducer dome should be aligned approximately at the level of the right atrium.
