How is that possible? 1. Air sacs (dead space) extend into the body cavity and into the wing and leg bones 2. Alternating ‘blockers’ ensure continuous (in-&exiratory) flow thru lung alveoli, without any residual volume

Our paper on why and how Transnasal Humidified Rapid-Insufflation Ventilatory Exchange (THRIVE) works was published in Anaesthesia. Cardiogenic Oscillations are key. Attached is a video of cardiogenic oscillations in action. https://t.co/GQJFlqTDEe

Ordinarily, PaCO2 rises by 0.5kPa/minute

During THRIVE, this is reduced to 0.15kPa/min - thus permitting prolonged apnoeic periods

How is this achieved?

HFJV occurs in an ‘open airway’, so all of the following apply:

1. Apnoeic ‘bulk flow’
2. Cardiogenic oscillatory mixing of tracheal-pharyngeal gas
3. Flushing of tracheal gas (by JV)
4. Transitional Jet flow

[JetVent Collaboration @jet_vent]

With open airway and cardiogenic oscillation (intensity of which is proportional to hypercarbia), Jet Ventilation delivers tracheal flushing and a jet transitional flow

Beyond generation 17, airway gas moves by diffusion only
