Flow differential pressure as measured at the patient wye using the bi-
directional transducer. Differential pressure is measured between the
high and low side proximal sense lines.

0
Flow differential pressure as measured at the patient wye using the
narrow scale transducer. Differential pressure is measured between the
high and low side proximal sense lines. The narrow scale transducer is
only used for differential pressures between -0.35 cmH

O and 0.35
cmH

O (approximately -15 Lpm to 15 Lpm).
FTb xx.xx Lpm
Flow in Lpm calculated from the differential pressure measured at the
patient wye using the bi-directional transducer.
