From: Bench experiments comparing simulated inspiratory effort when breathing helium-oxygen mixtures to that during positive pressure support with air

Figure 2

a) The relationship between pressure drop and flow rate, and b) the inspiratory effort during simulated unassisted spontaneous breathing at a fixed tidal volume (V t ) and respiratory rate (RR) are compared between non-linear (2xRp5) and nominally linear (2xFilter) airway resistances for medical air and for helium/oxygen 78/22.
