简要总结
This study assesses the feasibility of digital data collection for a randomized controlled trial in a quaternary pediatric intensive care unit and the effect of two commonly used mechanical ventilation modes on gas exchange (CO2) in children over 2 days after randomization.
This is a single-center, open-labelled, randomized controlled trial with two parallel 1:1 treatment arms: pressure controlled (PC) vs pressure-regulated volume controlled (PRVC) mechanical ventilation modes.
Use to routine digital data is essential to enable health learning systems and to provide rapid clinical trials readiness, as the pandemic has demonstrated. Despite availability of data to perform digital trials in PICU settings, these are yet scarcely done.

入选标准
- •Informed consent provided by the participant or the participant's parents or legal guardians. In case of an emergency situation, a physician who is independent of the research project must be consulted prior to inclusion in order to safeguard the interests of the test subject.
- •Admission to PICU at the University Children's Hospital Zurich
- •Need for mechanical ventilation for >60 min during PICU hospitalization. Need for mechanical ventilation will be based on clinical decision of the treating physician.
- •Need for an arterial line during PICU hospitalization. Need for an arterial line will be based on clinical decision of the treating physician.
- •Age <18 years
- •Weight >2 Kg
排除标准
- •Substantial air leaks around the endotracheal tube (>30%)
- •Cyanotic shunt lesions
- •Intracranial hypertension (i.e. traumatic brain injury or patients admitted after neurosurgery)
- •Pulmonary hypertension under treatment (i.e sildenafil or inhaled nitric oxide)
- •Time from start of invasive mechanical ventilation until time of screening is > 24 hours
- •Previous enrolment in the study in the past 30 days
- •Inability of the parents or legal guardians to understand the study due to linguistic or cognitive reasons
