Informationen:
                                    This BiPAP unit provides bi-level positive airway pressure,
through a nasal or nasal / oral mask, to assist patient
ventilation. An integral flow transducer senses whether the
patient is inhaling or exhaling by constantly monitoring the
amount of air flowing through the system. The system then
provides the appropriate amount of positive air pressure for
the function, i.e., more pressure during inhalation (IPAP),
less pressure during exhalation (EPAP).

The unit is available in four models: BiPAP S, BiPAP S/T,
BiPAP S-D, BiPAP S/T-D.

The BiPAP S unit offers two modes of operation:

•	CPAP (Continuous Positive Airway Pressure) - When the
control is set to either IPAP or EPAP, the unit provides
continuous pressure at the level you set for that function.

•	SPONTANEOUS - The unit cycles between inhalation (IPAP)
and exhalation (EPAP) levels as triggered by patient breathing.

The BiPAP S/T offers four modes of operation:

•	CPAP (Continuous Positive Airway Pressure) - When the
control is set to either IPAP or EPAP, the unit provides
continuous pressure at the level you set for that function.

•	SPONTANEOUS - The unit cycles between inhalation (IPAP)
and exhalation (EPAP) levels as triggered by patient breathing.

•	SPONTANEOUS/TIMED - As with the SPONTANEOUS mode, the unit
cycles between IPAP and EPAP levels as sensed from patient
breathing, but if the patient does not inhale within a
preset time interval, the unit cycles to IPAP. The time
interval is determined by the BPM (breaths per minute)
setting on the control panel.

•	TIMED - The unit cycles between IPAP and EPAP levels at
preset time intervals, determined by the BPM and % IPAP
(percent of breath cycle spent in IPAP settings on the
control panel).

The BiPAP S-D unit offers the same operating modes as the
BiPAP S, but all functions can be controlled by a Detachable
Control Panel (DCP). In addition, the following DC analog
output signals are provided for a recorder or oscilloscope:

•	P (Pressure) - The signal from the internal pressure
transducer indicates IPAP and EPAP levels (in cm H20 at the
measure point in the patient circuit).

•	Vt (Estimated Tidal Volume) - Signal from the internal
flow transducer indicates volume of air (in liters) inhaled
or exhaled with each breath during quiet breathing.

•	V (Total Flow Rate) - The signal from the internal flow
transducer indicates total air flow rate (in L/ min) through
the unit to the patient circuit. Total air flow consists of
the air flow necessary to satisfy circuit leaks (V|eak), and
patient breathing (Vest).

he BiPAP S/T-D unit offers the same operating modes as the
BiPAP S/T, but all functions can be controlled by a DCP. In
addition, it provides the same recorder output signals (
VT,7tot Vest and P) as the BiPAP S-D.	°' * ’

The Airway Pressure Monitor is designed to supplement
patient monitoring during ventilation with the BiPAP S/T-D
System. Its purpose is to notify medical personnel and/or
user of undesirably LOW (as in a disconnect situation) or
HIGH pressures at a specific point in the breathing cycle.
