Baska FESS Mask instructions

Single Use Instructions

To ensure integrity of mask, with gloved hands, occlude the airway opening of the connector end of the device with one thumb, hold the mask head with the other hand and place the thumb over the airway opening of the mask to seal. Apply pressure for 5 seconds to confirm there is no leak in the device.


Lubricate the entire mask liberally with a water soluble lubricant. - This is the key to a succesful insertion and placement.

With the tip of the mask mildly lubricate both upper and lower lips of the patient. Place the head and neck in slightly extended position. With the mouth open insert the device all the way down holding it at its stem. Do not pull on the lower jaw. Allow the lip to cover over the teeth during insertion. Do not twist or turn the device

If required, pull the tab gently to help negotiate the palato-pharyngeal curve. Release the tab as soon as the tip of the mask has passed around the curve.

Ensure the mask has been advanced sufficiently until resistance is encountered. In this position the tip of the mask is engaged into the upper end of the oesophagus. Check that the airway is clear - by observation if the patient is breathing spontaneously, or by gently ventilating if the patient is apnoeic. It may occasionally be necessary to withdraw the mask very slowly, 3-5 mm at a time until a clear airway is obtained. At this point secure the mask in position.

Complete and check the seal by closing the breathing circuit spill valve and applying pressure to the reservoir bag

If regurgitation is anticipated or is a high risk, suction should be connected to the suction port of the device before insertion and be left running continuously until the mask has been positioned correctly. Suction should also run continuously during removal of the device at the end of the procedure. During the procedure suction can be applied intermittently as required to clear any fluids or secretions. Maintaining suction continuously throughout the procedure is not recommended as it could predispose to post-operative sore throat due to the drying action of the air flow.

The vent must remain open to atmosphere at all times.
