“LUMENA”
Aerosol Minimizing NIV Mask for Adults Instructions For Use

Please read the following operating instructions carefully. They are a part of the product and should be available at all times.

Mask Description

The “Lumena” aerosol minimizing mask is an interface accessory meant to be connected to a ventilation device providing air/oxygen flow for patients in need of Non-Invasive Ventilation (NIV) The device is designed to generate the required pressure for the therapy whilst minimizing potentially harmful emissions into the environment.
The mask is comprised of several components, as shown in the following figure. Figure Index

Intended Use

The “Lumena” is a disposable, single-patient-use, oro-nasal mask intended to provide a patient interface for application of Non-Invasive Ventilation (NIV) to adults >30kg, while minimizing dispersion of bio-aerosols and aerosolized drugs into the surroundings. The mask is designed as an accessory for continuous single or double limb ventilators.
The AAV variant is meant for ventilators that do not contain a single fault safety mechanism. while the SE variant is to be used with ones that have adequate alarms and safety systems for ventilator failure, or an auxiliary safety mechanism such as a Whisper Valve to avoid airway obstruction/asphyxiation.
Warnings

• Do Not use the “Lumena” mask with patients not able to remove it independently, or with patients suffering from regurgitative conditions or a tendency to vomit. Doing so may cause asphyxiation.

• The mask is a non-vented mask. Always use an expiration valve in single limb setups – See “Use Setups” for further elaboration.

• In case of mask readjustment, or when removal of the mask is required, lower the ventilation pressure prior to mask removal to ensure safe adjustment.

• Use the “Lumena” mask only within the therapy pressure ranges indicated (i.e., 4-30 cmH2O); Exceeding said limits may lead to CO2 rebreathing / leakages.

• When using the Standard (Blue) elbow variant with a device without an adequate alarm, an auxiliary anti-asphyxiation valve (AAV) must be connected to prevent rebreathing in the event of ventilator failure.

• Patients with limited spontaneous respiration must be supervised at all times. The appropriate negative pressure / leak alarm on the ventilation device must be activated.

• Patients with obstructive and restrictive lung diseases should be assessed on an individual basis for suitability for the “Lumena” mask (e.g., with regard to the rebreathing of CO2).

• Do not place the mask over the patient’s face unless the therapy unit is switched on immediately.
  Doing so may increase the risk of CO2 rebreathing or result in an adverse effect on the therapy quality.

• When using the “Lumena” mask with an automatic trigger ventilator, exercise extra vigilance for patient ventilator asynchrony.

• Discontinue use of the mask if the patient has ANY adverse reaction to the use of the mask such as skin damage / irritation.

• There is a risk of fire associated with Oxygen equipment and therapy. Do not use near sparks or open flames.

• If oxygen is used, the oxygen flow must be turned off when the mask is not in use, so that unused oxygen does not accumulate within the device enclosure and create a risk of fire.

• When, and if applied, use only sealing gels or lubricants that are labeled “compatible with O2”.

• During oxygen usage, do not smoke in the vicinity of the device.

• Do not lubricate fittings, connections, tubing, or other accessories to avoid the risk of fire and burns.

• At a fixed flow rate of supplemental oxygen flow, the inhaled oxygen concentration will differ based on patient breathing pattern, leak rate, pressure settings used and mask selection.

Precautions

• The “Lumena” mask is intended for short-term use of up to 14 days. Do not use beyond said limit.
• The “Lumena” mask is meant for use in medical facilities by trained medical professionals.
• Do not use the device if the “Use by” date indicated on the package label has passed.
• The device is intended for single patient use only. DO NOT reuse, reprocess or sterilize. Reuse, reprocessing or sterilization may compromise the structural integrity of the device and / or lead to device failure, which in turn, may result in patient injury, illness or death. Reuse, or reprocessing may create a risk of contamination of the device and / or patient infection or cross- contamination, including, but not limited to the transmission of infectious disease(s) from one patient to another. Contamination of the device may lead to injury, illness or death of the patient.
• Inspect the mask package and contents to verify that no damage has occurred as a result of shipping, handling, and / or storage, and that no parts are missing from the pack. If any parts are noted as missing, DO NOT USE the device. Retain the package with the contents and notify your Inspir Labs Ltd. representative.
• In case of irritation from headgear, first, take off and readjust or try a different mask size. If irritation persists, cease usage of the mask.
• In case the mask does not fit, use the dimensions specified in Specifications section and refit a different size mask.
• Ensure that the suction tube is new and not reused or blocked for any reason.
• The kit contains small parts that can pose a choking hazard, keep away from children under 5 years.

Operations

Compatible Devices and Accessories
The “Lumena” mask can be combined with all units designed for carrying out the therapies described under “Intended Use”. Note that if unsuitable device combinations are used, the actual pressure in the mask may not correspond to the required therapy pressure.
Use Set-Up
The “Lumena” Mask is best used in the following circuitry:
Dual Limb:
Dual limb with Bacterial-Viral filterDual limb no Bacterial-Viral filter – For integral filtering ventilators Single Limb:
Note: Both single limb set-ups require a Bacterial-Viral filter and an expiration device.
Single limb with AAV modelSingle limb no AAV Note: The Standard elbow (Blue Elbow) model must be used, with either ventilator, with adequate alarms or a circuit that contains an AAV to provide access to room air in case of ventilator malfunction
Wearing the Mask
Caution! Always connect the expiration device downstream to the filter! Failing to do so may result in contamination of the environment.

1. Leave one of the lower headgear clips free.
   Make sure the oxygen port cap is tightly secured.

2. Place the headgear over the patient’s head and hook the headgear free clip back onto the mask.

3. Adjust the headgear so that the mask seals on the face but is not too tight.

Exhaled Air System
Warning! The “Lumena” mask does not have its own exhalation system! It may only be used in combination with therapy devices or circuits which have an active exhalation valve! Otherwise there is the risk of CO2 rebreathing and suffocation.
Therapy Pressure Ranges
The “Lumena” mask is meant for usage in a particular therapy pressure range (4-30 cmH2O) only.
Connecting the suction tube to the wall suction
Push the suction tube into the wall outlet as shown in the figure below. Ensure that the connection to the hose is secure and airtight. Connecting the Suction Tube to the “Lumena” Mask
Connect the other side of the suction tube to the suction port of the “Lumena” mask as shown in the Figure.
Ensure that the connection to the port is secure and airtight. Connecting the Hose to the “Lumena” Mask
Push the hose of your therapy unit into the machine outlet. Ensure that the connection to the hose is secure and airtight. The connection must not be loosened by the therapy pressure.
When using a set-up with a Bacterial-Viral filter, connect the filter to the Elbow as shown in the Figure.
Caution! – Do not connect the filter upside down. Push the Hose onto the mask elbow/filter and ensure the hose fits tightly. Humidifier
The “Lumena” mask can be used with both cold and warm-air humidifiers. Never set the humidification level so high that condensation forms in the air hose or in the mask. Follow the instructions for use of your humidifier and therapy unit.
Mask Removal
To remove the mask, pull the Blue quick release clip to the side, and pull the mask and headgear up and over the patient’s head.

Cleaning

The “Lumena” is a single patient disposable mask that should be replaced in case it is heavily soiled with the patient’s secretions. However, if it is only lightly soiled, the mask may be cleaned using soap and water. Do not disassemble the mask when cleaning.
Always follow the cleaning instructions. Some cleaning products may damage the mask, its parts and their function, or leave harmful residual vapors.

Disposal

After use, this product may be a potential biohazard. Handle and dispose of in accordance with accepted medical institutional practice and applicable local, state and federal laws and regulations.
