Picture of a T-piece resuscitator device with humidified T-piece circuit attached to a Neopuff.
T-piece resuscitator device with humidified T-piece circuit and heater in place. Proximal, distal and distal attachment of the pressure transducer are indicated.
Figure 4.
PIP (cmH2O) measured at different places in the ventilation circuit.
A) standard tubing, B) heater with associated tubing (not heated), C) associated tubing without heating, D) distal associated tubing and E) heater with associated tubing heated. The box plots show median values (solid black bar), inter quartile range (margins of box), and range of data proximal (white boxes) and distal (grey boxes).
Figure 5.
PEEP (cmH2O) measured at different places in the ventilation circuit.
A) standard tubing, B) heater with associated tubing (not heated), C) associated tubing without heating, D) distal associated tubing and E) heater with associated tubing heated. The box plots show median values (solid black bar), inter quartile range (margins of box), and range of data proximal (white shaded boxes) and distal (grey shaded boxes).
