PAR and BR bulbs share the same voltage of 120VAC and have the same Kelvin degree color code as all light bulbs: 1  2700K (warm white). 2  4100K-5000K (cool white). + 3 5000K (daylight color).
Wandering baseline is signal noise or artifact on an ekg caused by loose connections, patient breathing, etc. .. But nothing to do with the activity of the heart. In brief: Not to worry. Wandering baseline is signal noise or artifact on an ekg caused by loose connections, patient breathing, etc. .. But nothing to do with the activity of the heart.
Each patientâs ECG is unique. The patientâs physical size, skin type, age, and pathology as well as where the electrodes are. placed, influence the results of the tracing. Poor signal quality can cause noise or artifact on the ECG, which in turn leads to. inaccurate analysis of the ECG.1. This document will guide you through all the elements that can affect ECG tracings and provide you with tips on how to. reduce artifact in your practice.
