Prolonged weaning: from the intensive care unit to home

Area of Science:

• Critical Care Medicine
• Pulmonology
• Respiratory Therapy

Background:

• Mechanical ventilation weaning is classified as simple, difficult, or prolonged based on duration and spontaneous breathing trial (SBT) success.
• Prolonged weaning, defined by failing 3 SBTs or persistent ventilation after 7 days, impacts a small but resource-intensive patient group.
• Understanding individual patient factors is crucial for effective treatment and prognosis in prolonged weaning.

Purpose of the Study:

• To define the characteristics and management strategies for prolonged mechanical ventilation weaning.
• To highlight the role and success factors of specialized weaning units (SWUs).
• To address the needs of patients requiring long-term home mechanical ventilation.

Main Methods:

• Review of prolonged weaning definitions and classifications.
• Discussion of the criteria and benefits of transferring patients to SWUs.
• Consideration of challenges in long-term home mechanical ventilation.

Main Results:

• Prolonged weaning necessitates significant ICU resources.
• SWUs provide specialized, protected environments for stable but ventilated patients.
• Key SWU success factors include staffing, goal setting, and psychosocial support.

Conclusions:

• Individualized patient assessment is paramount for managing prolonged weaning.
• SWUs are vital for optimizing care for complex weaning patients.
• Careful planning for caregivers and equipment is essential for successful long-term home mechanical ventilation.
