Clinical Definition
Pressure support involves:
- Ventilatory Assistance: Reduces work of breathing
- Pressure Differential: IPAP minus EPAP
- Breathing Support: Assists with ventilation
- Adjustable Support: Can be customized for individual needs
- Comfort Enhancement: Makes breathing easier and more comfortable
Pressure support typically ranges from 2-20 cm H2O, with higher values providing more ventilatory assistance.
Etymology & History
Reference Values & Interpretation
Normal Values
Effective pressure support should provide adequate ventilatory assistance while maintaining patient comfort and good patient-ventilator synchrony.
Abnormal Values
Pressure support that is too low may not provide adequate ventilatory assistance, while excessive pressure support may cause discomfort or hyperventilation.
How It's Measured
Pressure support is determined by setting the difference between IPAP and EPAP during bilevel PAP titration, adjusting based on ventilatory needs and patient comfort.
Role in Diagnosis
Pressure support is used in bilevel PAP therapy for patients who need ventilatory assistance, including those with neuromuscular disorders, obesity hypoventilation syndrome, or respiratory muscle weakness.
Role in Treatment
Pressure support is essential for effective bilevel PAP therapy in patients who need ventilatory assistance beyond simple airway patency.
