2.4 Usage of Patient Circuit
• Only use the iSleep 20 with a mask and a patient tube recommended by
Breas Medical AB and your health care professional.
• Do not breathe in the connected patient circuit unless the iSleep 20 is
turned on and operating properly.
• Do not use patient hoses or tubes made of electrically conductive or static
material.
• Always use a new mask and a patient tube recommended by Breas Medical
AB when the iSleep 20 is to be used by a new patient.
• Patient connected parts and filter must be replaced regularly to ensure cor-
rect function of the iSleep 20. All replaced parts must be disposed of
according to local environmental regulations regarding the disposal of used
equipment and parts.
• If the patient is using a full face mask (covering mouth and nose), the mask
must be equipped with a safety entrainment valve.
• Make sure that the leakage ports are never blocked or obstructed. These
ports are used for ventilating the mask in order to prevent re-breathing of
exhaled air. Re-breathing of exhaled gases for longer than a few minutes
can, in some circumstances, lead to suffocation.
• At low CPAP pressures, the air flow through the leakage ports may be inad-
equate to clear all exhaled gases from the mask. Some re-breathing may
occur.
