The importance of tidal volume and its monitoring during high-frequency ventilation

Abstract

Even though High-Frequency Ventilation (HFV) meets criteria defining so called protective ventilatory strategy, HFV is not widely used in the clinical practice. Rational initiation of HFV and consequent maintenance of a constant ventilation belong to the limiting factors.

Tidal volume is a parameter playing a crucial role in HFV. In the initial phase of HFV, monitoring of tidal volume allows reaching normocapnia promptly.
