(OSAHS) in patients over 30 kg, breathing spontaneously. This device is not intended to provide
assistance to vital functions. It can be used at home or in healthcare centers (hospital or clinics). It is
also designed for hassle free travelling and can be used on airplanes.
The S.Box heated humidifier is an accessory designed to warm and add moisture to the air flow
delivered to the patient by the SEFAM S.Box device, for the treatment of Obstructive Sleep Apnea–
Hypopnoea Syndrome (OSAHS). It is intended for use by adult patients in either the homecare or the
hospital environment.

Sefam S.Box Features of the device 5
NOTE: The EMISSION characteristics of this device allows the machine to be used in industrial zones
and in healthcare centres (class A defined in the CISPR 11). When it is used in a residential area
(class B defined in the CISPR 11 is normally required), this device may not provide enough protection
for communication services with radio frequencies. Users may have to take certain measures, such
as the repositioning or the reorientation of the device in order to correct for this.
Contra-indications
Studies have shown that using positive pressure can be contraindicated in certain patients with one
of these pre-existing medical conditions:
Severe bullous emphysema
Pneumothorax
Pneumocephalus, trauma or recent surgery with sequela of cranio-nasopharyngeal fistula.
Decompensated cardiac insufficiency or hypotension, particularly in case of decreased blood
volume or cardiac arrhythmia
Dehydratation
Tracheotomy.
Furthermore, due to the fact that positive pressure affects the cardiac output in certain heart failure
patients, it is recommended that patient blood pressure and heart rate are carefully monitored when
starting treatment at an effective pressure. The risks and benefits of treatment by Continuous
Positive Airway Pressure must be individually evaluated in such subjects. This evaluation must take
into account the fact that the device can be adjusted to deliver pressures up to 20 cm H2O, and under
certain defect conditions, static pressures up to 40 cm H2O are possible. The device must not be
used then, if such pressure level presents a risk to the patient.
Essential performance of the device
The essential performance of the SEFAM S.Box®is to deliver a pressure equivalent to that of the
adjusted pressure ± 0.5 cm H2O.
The device was designed to maintain basic safety and essential performance without maintenance
regarding electromagnetic disturbance during the lifetime of the machine. However, in case of failure
the device has to be repaired by authorized persons who will use original parts only.

Sefam S.Box Features of the device 7
Features of the device
The SEFAM S.Box®can operate either in constant mode (CPAP), it then delivers a constant pressure
level, or automatic mode (Auto-CPAP) where the pressure changes between a minimum pressure
and a maximum pressure depending on the detected respiratory events. When selected, the AUTO-
CPAP mode will be activated 5 minutes after starting treatment.
Heated humidification
This function allows to control the power supplied to the heater plate depending on the air flow, and
to regulate the heating power to maintain the difference in temperature between the water and the air
constant. The device is delivered with an installed side cover and depending on the selected
configuration, it may be delivered with a heated humidifier which needs installing. In this case, the
side cover must be removed from the device and replaced by the humidifier including the heater plate
and the humidifier chamber (refer to the patient manual for the setup). The presence of the
humidification system is automatically detected by the machine and the heated humidification
function starts and stops simultaneously with the device.
Intelligent Start
This feature permits the patient to start the treatment automatically at the first breathings in the
mask, without using the start / standby button . It can be activated or deactivated by following
the instructions of paragraph ”1. Setting menu” page 19.
Mask Fit & Go
Before starting the treatment and when the device is in standby mode, the patient can check the air
tightness of his/her mask by using the touch button . The level of unintentional leak is displayed
and in case of undesired leak, the patient can adjust his/her mask.
Mask unplugged
When the patient removes his mask, the device automatically switches to low power. The machine
will restore normal power when the mask is reconnected (pressure delivered above 3 cm H2O) or if
the start / standby button or the ramp button is pressed. If the mask is unplugged for more
than 5 minutes, the compliance session is stopped and recorded, and the device will automatically
turn off after 30 minutes.
Note:
If the patient uses a resistive interface (nasal pillows mask), a specific calibration of the pneumatic
configuration may be performed so that the device can detect that the mask is unplugged (Ciruit Select
function).
Comfort Control Plus
The Comfort Control Plus CC+ is intended to increase the treatment pressure while inhaling and to
decrease it while exhaling to make the patient's breathing more comfortable during the treatment. It
can be activated during the ramp or the treatment. In both cases, three levels are available in order to
get an optimal comfort.

8 Features of the device Sefam S.Box
Ramp function
The ramp function makes it possible to gradually increase the pressure to help the patient fall asleep.
If it is activated, it starts automatically when the device is switched on (if the ramp time is different
than zero). Pressing the ramp button deactivates (and by pressing again reactivates) this
function. There are two types of ramp:
T RAMP Time ramp: you can determine the ramp time
I RAMP Intelligent ramp: the ramp time is automatically determined by the device.
Time ramp
In CPAP mode, the treatment begins at a reduced pressure called Ramp pressure (ramp start
pressure), and then the pressure rises up to the prescribed pressure (during the ramp time). If the
T Ramp function is deactivated, the pressure increases immediately to the prescribed pressure.
In AUTO-CPAP mode, this function is used to delay the activation of automatic operation (during the
latency or ramp time). In the case where the Ramp pressure (ramp start pressure) is less than the
minimum pressure, a progressive increase in pressure will be done from the Ramp pressure to the
minimum pressure. If the function is deactivated, the pressure remains at the Ramp pressure within
the first 5 minutes of treatment and then switches to automatic operation.
T Ramp function in CPAP mode
T Ramp function in Auto-CPAP mode
The symbol is displayed in the status bar and you can adjust the Ramp pressure, the ramp time
or latency time and the maximum ramp time (if the Ramp pressure is below the prescribed pressure).
Intelligent ramp
The I Ramp function permits the beginning of the treatment at an adjustable Ramp pressure (ramp
start pressure), then a faster increase pressure in the CPAP mode or the activation of the automatic
operation in the Auto-CPAP mode as soon as the device starts to detect respiratory events indicating
that the patient has fallen asleep.
The symbol is displayed in the status bar. The I Ramp stops automatically when the maximum
ramp time bas been reached (45 minutes).

Sefam S.Box Information and settings 9
Information and settings
The adjustment of the therapeutic pressure must be determined by the prescribing physician for
each patient individually, with the configuration of the equipment to be used, including the
accessories. The correct installation and positioning of the patient interface are critical to the proper
operation of the device.
WARNING:
Before setting the device, confirm that the product delivers an air flow when it is in operation mode. Otherwise,
stop the machine immediately and contact the technical support.
Settings are accessible directly on the interface of the device, via a Bluetooth connection (tablets/cell
phones apps), via a configured SD card or remotely through S.Box®Wi-Fi module or S.Box®modem.
You can also adjust the device with the SEFAM Analyze software, by connecting the machine to a
computer with a USB cable or a wireless connection.
CAUTION:
The USB connection inhibits automatically any Bluetooth communication.
The most recent compliance data are recorded by sessions in the device memory and on the SD card
up to one year for 8 hours of operation per day. They can also be retrieved by wired or wireless
connection with the PC software, on the SD card or by modem. Using SEFAM Analyze, you can
analyze the compliance data, the use of the device by the patient and the treatment efficiency.
