Internal Jugular Ultrasound Measures During Respiration in Children
Project Aims: The purpose of this study is to determine the size of the right internal jugular vein (RIJV) in children with normal respiratory physiology during the respiratory cycle and evaluate the reliability of those measurements.
Hypothesis: Ultrasound measurements of internal jugular vein collapse of children can be reliably measured in the respiratory cycle.
Intervention: We will ensure that the patient is not having any respiratory symptoms or signs of dehydration. A clinical asthma score will be assigned using the Modified Woods pulmonary index scoring system. The Gorelick Dehydration Scale with also be calculated.
Using bedside ultrasonography with the Sonosite Titan ultrasound machine, each measurement will be taken with the subject lying in bed with the head of the bed elevated at 45 degrees with the subject's head in the neutral position and then turned 45 degrees leftward. Measurements of the internal jugular vein at maximal inhalation and exhalation will be recorded. Reliability calculations will be assessed.
