TECHNICAL DESCRIPTION

The VECTOR et CPAP is a therapy device for treating obstructive sleep apnea.

In addition to the conventional CPAP-mode, the device offers in FLEXLINE-mode a pressure increase during inspiration and pressure reduction during expiration which is proportional to the individual breath flow.

To generate the necessary pressure, the device is provided with an electronically controlled blower. In order to keep the stress for the patient as low as possible, the blower has been designed with a high reserve capacity and a quick control response.

The pressure is measured directly in the mask and constantly controlled by the device. Consequently, the breathing work for the patient is a easy as possible.

There are two separate tubings in the device. One is for respiratory air and one is for the convection air required for cooling the electronics.

In addition to the mask alarm, the device offers another safety function, the power failure alarm. It automatically restarts the motor after power restoration.

The device contains a built-in microcontroller which controls all of its functions. A quartz alarm clock further adds to the comfort when using the device. Further comfort functions include a soft start ramp, the automatic start-stop function and the adjustable display brightness. While passing through the device, the air is heated a little, so that it has a higher water absorbency. When indoor air is dry in winter, the mucous membranes in mouth and nose may become particularly dry. This is unpleasant and may even cause infections in exceptional cases. For that reason, a therapy might require air humidification.

AquaDROP et, a clip-on humidifier is available as

accessory for the device. If necessary, just click the humidifier onto the device. Remove it by pressing its locking key.

The heater levels are set in the heater menu. The selected heater level is displayed as in the display of the device while the humidifier heating is switched on.

For more information please see your

AquaDROP et operating instructions or contact

your specialized dealer.

NOTES PRIOR TO FIRST USE

Never turn the device on if you kept it in a very cold environment. Wait for approx. 1 hour until its temperature compensation is completed.

Regularly check the air filter cassette and regularly exchange it as described on page 18. Never use the device without air filter.

Clean your mask system regularly and check all accessory parts, particularly the therapy tubing, the mask and the head gear. We recommend that you wash your face before going to sleep, in order to remove fat and cosmectics from your skin. This increases the service life of the mask and helps to prevent irritations of the skin.

Make sure the measurement tube is unobstructed at all times. Avoid ingress of water into the measurement tube during cleaning. If water droplets should have accidentally entered the measurement tube they must be carefully and thoroughly removed.

Please strictly observe the following setup instructions:

• Do not place the device in the vicinity of a heating source. Air circulation – particularly that below and behind the device – must not be impaired by furniture, curtains or cushions.

• Set up the device next to your bed. Place it on a firm and flat surface of your bedside cabinet.

• During mobile use, the device must also be placed on a firm and flat base, which must have an edge to protect the device from falling off.

ALARM FUNCTIONS

POWER FAILURE

If a power faiure at night would go unnoticed as a result the patient would breathe used air from the therapy tubing all night. To avoid this the device is equipped with an alarm mechanism that warns you with a 5 seconds delay if power or a fuse fail at night. You will be woken up with an acoustic signal so you can take the mask off your face and breathe fresh air. The alarm is turned off by pushing the operating button. After power supply is re-established the motor starts automatically and the display will show the following message:

CHECK POWER FAILURE WARNING

NOTE: T o check the power failure alarm, the device must have been connected to the power cord and turned on for at least half an hour.

Use the device with running blower and then pull the power plug out of the wall socket. Now the acoustic warning signal should sound. Check once a month if the signal sounds long enough (reference value: at least 3 minutes).

After pushing the operating button or turning on the power supply again the signal will stop.

MASK ALARM

This alarm function is activated only if the automatic function is turned off. If the mask has slipped off your face or if the tubing is pulled off the device, the device is not turned off automatically, but emits a visual and audible alarm. However, this additional safety function requires that you turn the device on in the evening and off and in the morning with the operating button (ON/OFF).

CHECK MASK ALARM

Use the device with running turbine in the manual mode (automatic mode OFF). The mask is open but not applied to your face. After a short time, an audible signal is emitted.

CPAP
