1. Introduction
1.1 Device
The SLE1000 is a CPAP driver for delivering an air-oxygen treatment gas to patients via
nasal prongs or nasal mask. The SLE1000 is intended for providing CPAP to treat infant and
neonatal patients with compromised respiratory systems while in an acute or sub-acute
hospital environment.
The SLE1000 can be operated from either wall serviced, compressor or bottled pressurized
air and oxygen sources in the range 2 to 7 bar.
The SLE1000 has been designed so that it can be used with only a compressed air supply.
The SLE1000 automatically corrects the flow rate, to maintain the set CPAP or maintains the
set flow.
‘Typical’ flow-CPAP relationship is shown by the centre line in the nomogram below. This is
the relationship produced by common Nasal Generators.. The line also represents the
SLE1000 default calibration settings.
The highlighted area in the nomogram below represents the whole operating range. The
SLE1000 will alarm if the patient leak or the exhaust impedance (block) is excessive and
causes the automated flow correcting to reach a boundary of the operating zone.
