Brief Summary:
Respiratory disorders are the leading cause of respiratory failure in children. Thousands of children are admitted to a pediatric intensive care unit each year and placed on mechanical ventilators. Despite over 40 years since the first pediatric-specific ventilator was designed, there has been no specific cardiopulmonary directed therapy that has proven superior. While mechanical ventilation is generally lifesaving, it can be associated with adverse events. There is evidence building to suggest that adopting a lung protective ventilation strategy by the avoidance of lung over-distension and collapse reduces death. Therefore, timely discovery of these two lung conditions is extremely important in order to mitigate the effects associated with positive pressure mechanical ventilation. The investigators research team has extensive research experience with a non-invasive and radiation free medical device called electrical impendence tomography (EIT). EIT is intended to generate regional information of changes in ventilation. Meaning it can detect this collapse and overdistension. This additional source of information could help fine tune the mechanical ventilator. A baseline of understanding of how often this occurs in the patients the investigators serve is required. Therefore the investigators propose an EIT observation study in their pediatric ICU patient population.

Mechanical Ventilation
Infants and Children requiring mechanical ventilation

Primary Outcome Measures :
  1. Distribution of Ventilation [ Time Frame: Every 24 hours or after PEEP changes ]
    Distribution of ventilation as determined by changes in impedence in layers or quarters.

Secondary Outcome Measures :
  1. Distribution of Ventilation Changes Over Time [ Time Frame: Every 24 hours for the duration of mechanical ventilation ]
    Changes if the distribution pattern over time

Other Outcome Measures:
  1. EIT Guided Ventilation Algorithms [ Time Frame: Images pre change in PEEP compared to post change ]
    Comparision of distribution of ventilation algorithms

Study Population
In a prospective observational trial we will objectively measure regional distribution of ventilation by EIT in patients who require mechanical ventilation.

Inclusion Criteria:

  • All patients who require mechanical ventilatory assistance. This includes invasive and noninvasive ventilation.
  • Ages 1 day (full term defined as > 37 wks GA) to 17 years of age.

Exclusion Criteria:

  • Patients with unstable spinal injuries or diseases
  • Body mass index > 50
  • Active implant such as pacemaker, ICD, or diaphragm pacer
  • Patient who is having cardiac arrhythmias
  • Skin integrity issues in the area that the belt / electrodes will be placed, such as ulcers or open wounds
  • Dressings or chest tubes that prohibit the placement of electrodes in the proper plain.
  • Open chest
  • Flail chest within the regional plain of the belt / electrodes
  • If the medical team feels that the patient is not appropriate to enroll in the study based on medical, social or emotional concerns
  • If the patient is too unstable to position the belt / electrodes and/or transition to the Draeger ventilator
  • Patient has been supported on mechanical ventilation for longer than 48 hours prior to enrollment
  • Post-operative spinal fusion patients
