What does High Frequency Percussive Ventilation (HFPV) deliver?

High Frequency Percussive Ventilation (HFPV) is characterized by its delivery of rapid, low volume breaths. This ventilation strategy allows for increased lung recruitment and improved gas exchange by utilizing high frequency and low tidal volume, which minimizes barotrauma and improves ventilation-perfusion matching. The rapid breaths provided by HFPV help in effective airway clearance and can be particularly beneficial in patients with conditions like atelectasis or severe lung disease. This mode of ventilation distinguishes itself from standard mechanical ventilation methods, as it focuses on delivering breaths that can enhance pulmonary function while minimizing potential lung injury associated with higher volume ventilation strategies.
