[Mechanical ventilation in infants and children].

Area of Science:

• Critical Care Medicine
• Pediatric Pulmonology
• Respiratory Therapy

Context:

• Acute respiratory failure necessitates mechanical ventilation when immediate causative treatments are not feasible.
• Understanding the unique respiratory physiology of children, including their high metabolic rate and specific respiratory characteristics, is crucial for effective management.
• The causes of acute respiratory failure extend beyond pulmonary conditions, encompassing a broader range of pathologies.

Purpose:

• To outline the indications and application of mechanical ventilation as a palliative treatment for acute respiratory failure in pediatric patients.
• To describe the different types of mechanical ventilators used for infants and children aged 28 days to 15 years.
• To emphasize the critical need for continuous supervision during mechanical ventilation in this age group.

Summary:

• Mechanical ventilation serves as a palliative treatment for acute respiratory failure when definitive treatments are not immediately available, addressing respiratory pump defects.
• Pediatric patients exhibit distinct respiratory characteristics due to their high metabolic status, influencing ventilation strategies.
• Two main categories of ventilators are employed for children aged 28 days to 15 years: continuous flow, time-controlled, limited pressure ventilators for infants, and controlled volume ventilators for older children, with modifications for younger ones.
• Continuous monitoring is mandatory for all infants and children receiving mechanical ventilation.

Impact:

• Provides essential guidance for clinicians managing pediatric acute respiratory failure.
• Highlights the importance of age-specific ventilator selection and settings in pediatric critical care.
• Underscores the necessity of vigilant patient monitoring to ensure optimal outcomes in mechanically ventilated children.
