In this ventilatory strategy, ultra-high respiratory rates (180-900 breaths per minute) are coupled with tiny tidal volumes (1-4 mL/kg) and high airway pressures (25-30 mm water). [3] This is a commonly accepted ventilatory setting for premature infants and has now also been used in small critical care unit studies on patients with ARDS, with reports of improving oxygenation and lung recruitment. [4, 5]

While this setting cannot currently be recommended for routine ED use, it may in the future be found appropriate for the management of patients with ARDS.
