Fig 2. Heat maps depicting intensity of ventilator support in preterm lambs.

Fig 2

Types of respiratory support are graded according to decreasing invasivity and intensity of support: Red—intubated and mechanically ventilated (MV); orange–intubated with continuous positive airway pressure (ET CPAP); green–nasal CPAP (nCPAP); light blue—nasal humidified high flow (nHHF) and blue—no support (none). Lambs within Sal/Sal, LPS/Sal and LPS/hAEC groups are represented in left-to-right in the order of delivery. The first 6 days of respiratory support are presented as columns, from left-to-right, as the proportion of time spend on any mode of respiratory support on that day.
