Figures

Figure 1
Figure 1
Shows an example of a mask with an inbuilt leak and anti-asphyxia valve.
Figure 2
Figure 2
Shows suggestions for switching from a vented mask to a non-vented mask attached to an antibacterial/antiviral heat moisture exchanger (HME) filter, then attached to a controlled leak (Whisper swivel II (Philips, Murraysville, USA). Left picture shows a child mannequin wearing a non–vented nasal mask. Centre picture a full face mask and right picture a total face mask. Note the position of the HME and Whisper Swivel controlled leak (labelled and circled).
Figure 3
Figure 3
Top left hand photograph demonstrated that oxygen should be entrained using a dedicated connector where possible (circled). If this is not possible the top right hand photograph illustrates the position of an oxygen connector attached to the ventilator tubing (circled). It can also be placed on, before intentional leak (bottom left photograph) or before the “active valve”, bottom right photograph.
Figure 4
Figure 4
Picture shows a child mannequin wearing a non–vented nasal mask with the active valve circuit set up. Note the position of the HME and active valve in the circuit. The same set-up can be used for a face mask or a total face mask.
Figure 5
Figure 5
The three photographs show a child mannequin with a tracheostomy. The left picture shows a active valve circuit. The centre picture a controlled leak circuit and the right picture a double limb circuit.
Figure 6
Figure 6
This picture shows the set-up of heated humidification if required in a child with a tracheostomy. Note the position of the filter on the expiratory limb to protect the ventilator and the environment.
