Ventilation management is a crucial aspect of critical care medicine, serving as a cornerstone in emergency, internal, and hospital medicine. Several ventilation modes exist that are important for patient care in inpatient settings and for immediate stabilization. Pressure support ventilation (PSV) is a mode designed to maintain spontaneous breathing in patients with both acute and chronic requirements. PSV is characterized by patient-triggered, pressure-limited, flow-cycled breaths, and each breath is supplemented with a consistent positive pressure. Evidence-based practice emphasizes the role of pressure support mode in liberating patients from mechanical ventilation.PSV operates as a flow-limited ventilation mode, providing pressure during inspiration until a preset flow threshold is attained. The inspiratory pressure level can vary from 5 to 20 cm H2O, depending on the patient’s ventilatory needs. A pressure support of less than 5 cm H2O reduces resistance by overcoming ventilator dead space, including the circuitry and its components. Increased pressure support levels are introduced to alleviate the work of breathing (WOB) by supplementing the patient’s spontaneous effort with positive pressure. When using pressure support levels between 10 and 12 mL/kg, the ventilator takes over all the WOB. Patients consistently govern breath frequency, duration, and flow in a PSV environment. The volume of each breath is directly influenced by set pressures, patient effort, and other mechanical settings that may counteract ventilation. This activity delineates the indications, contraindications, and clinical benefits of utilizing pressure support in ventilated patients to resume spontaneous breathing.
