Cleaning and Maintenance FAQs

How should I clean the exterior of my ventilator?

Wipe the exterior with a hard surface disinfectant wipe.

How often do NIPPY Ventilators require servicing?

A safety and calibration check should be carried out annually. After 10000 run hours a complete service is required.

How often should I change the rear filter?

The back air filter should be checked monthly and changed when it becomes grey. These should not be washed.

Alarm FAQs

What does the High Flow Alarm indicate?

HIGH FLOW – Requires immediate response and is signalled by a red flashing bell and is a continuous beep. This can indicate disconnection, a circuit leak or high lung volumes leading to high flows.

What does the Low Flow Alarm indicate?

LOW FLOW – Requires immediate response and is signalled by a red flashing bell and is a continuous beep. This may indicate an airway blockage, circuit occlusions or additional flows into the circuit such as oxygen.

What does the disconnect alarm indicate?

DISCONNECT – Requires immediate response and is signalled by a bell flashing and a continuous beep. This alarm activates when the ventilator senses the patient is disconnected.

What does the Apnoea alarm indicate?

APNOEA – If set, this alarm indicates cessation of spontaneous breathing. It may also alarm due to the patient becoming disconnected from the machine or a blockage in the tracheostomy tube due to secretions.

What is the mains fail alarm?

MAINS FAIL ALARM – IIf the breathing circuit becomes disconnected the alarm will be activated after 10 seconds.

What does the high breath rate alarm indicate?

HIGH BREATH RATE – If the high breath rate alarm has been set the NIPPY will alarm if the patient’s breathing rate is higher than that set.

What does the notice ‘Running on battery’ indicate?

RUNNING ON BATTERY – A warning alarm that alerts the practitioner/carer that the ventilator is running from the battery and not from mains power.

What does the low battery alarm represent?

When the battery is almost depleted the battery icon will flash and change colour to red.

When the battery is depleted an alarm will sound, accompanied by an on-screen message, “Battery Power Running Low”

When battery power reaches a critical level, the alarm will change to a continuous tone and the on-screen message will change to “Battery Power Exhausted. About to switch off. Connect to Mains Power Now”

After auto power off, the constant alarm will continue until the Mute is pressed.

Battery FAQs

What power options are there for my NIPPY Ventilator?

NIPPY S+, ST+, 3+ and Junior+ may be powered from the mains, external battery or internal battery.

What happens to the battery when I run the ventilator on mains power?

When running on mains, the ventilator will recharge its own internal and/or external battery. Charge time is normally around 8 hours, per battery, depending on the ventilator settings.

Will the battery charge when the ventilator is not running/in use?

Yes, batteries will also be charged when the NIPPY is connected to the mains supply but not running. Leave connected to the mains supply in between periods of use to keep the batteries charged or to recharge ready for the next use.

When an internal and external battery exist, with mains power connected, how are the batteries charged?

When an external battery is connected to a machine, which has an internal battery, each battery is charged to approximately 90%, starting with the internal one. When the battery(s) are charged, the charge will terminate and the battery will be monitored to maintain its charge.

Which power supply is used first?

The ventilator will select its power source, according to the power available, in the following sequence:-

  1. Mains Electricity
  2. External Battery (if connected)
  3. Internal Battery (if fitted)

In order to save battery power, the ventilator will always run on mains electricity if it is present.

What happens if the mains power fails or is disconnected?

If the mains fails or is not connected, the ventilator will select the external battery as the next choice. The external battery, if present, will always be run flat before the internal battery is selected.

If there is no external battery, the ventilator will switch to its internal battery.

If there is no internal battery the ventilator will shut down and alarm.

How do I check Battery Run Times?

Battery run times are dependent on the ventilator settings and the amount of leak. High pressures and /or high breath rates use power and therefore shorten run times. Large leaks use power and shorten run times.

The expected run time can be displayed on screen. Double press the SET button to display a bar graph of run time. The time for each battery connected will be calculated, according to the ventilator settings, and shown on the screen.

What run hours should I expect from the batteries?

The run time may be as long as 12 hours for low values of CPAP with only moderate leak or as short as 4 hours for Pressure Support at maximum pressure with quite severe leaks. Battery run times will typically be 20% more in IPPV mode because of the absence of the exhale port leak.

Run times will be shortened by higher breath rates and/or higher EPAP levels. Typical Running Times with EPAP set to minimum @ 20BPM.


Run Time (Hours)

Min Run Time (Hours)



















How can I test the internal battery?

Testing your battery regularly (once a month at least) is good practice but should also be carried out if the battery if the running time seems low, a fault is suspected, or to confirm that the battery is in good working order.

  1. Ensure the battery is fully charged.
  2. Run the ventilator from the battery until the low battery alarm operates and record the running time. Look up run time in the table. If the battery is not achieving minimum run time arrange to replace it.
  3. If the battery is good, fully recharge it immediately after testing.

How should I maintain my battery for reliable operation?

  1. Always make sure that the battery is fully charged before use.
  2. If you are in doubt about your battery’s state of charge, charge for at least 24 hours.
  3. If running time suddenly seems considerably shorter than normal, make sure that the battery is fully charged, if the run time remains short after full charging, please contact technical advice.
  4. Check the running time of your system regularly; allow the battery to run to low charge once a month (Please see How can I test my battery as above).

How frequently should the external battery be replaced?

The end of life is defined by the maximum running time falling to 75% of that of a new battery. For a battery that is used occasionally service life is 2 years.

Replace the battery when running times drop below those indicated or after 2 years.

How frequently should the internal battery be replaced?

The internal battery should be replaced every 2 to 3 years or after 10000 hours use. It should also be replaced if the run times are shorter than expected.

Who should replace the battery?

The user cannot replace the battery. Please refer your ventilator to a suitably qualified technical personnel for battery replacement.

Can other types of batteries other than those issued from Breas Medical be used with the NIPPY range of products?

No, please DO NOT attempt to fit any battery other than the approved type. Fitting of any other type of battery could lead to personal injury and damage to the ventilator.

Travel FAQs

Can I travel with my NIPPY Ventilator?

All models in the NIPPY 3+ range are equipped with a universal input power supply. This means that you can travel anywhere in the world and plug into the local electrical supply, provided you use the correct mains lead or an adaptor.

The voltage must be between 100 and 240 volts ac. Please check before travelling. Some countries have very unreliable supplies. You should consider this before travelling.

What are the transport regulations about travelling with batteries on aircraft?

The transport of lithium-ion is regulated by various bodies (IATA, IMO, ADR, US-DOT) that follow the United Nations “Recommendations for the transport of dangerous goods.”

Certain restrictions apply to the carriage of lithium-ion batteries even when carried by passengers as baggage. Only batteries that have successfully passed the tests outlined in Part III, subsection 38.3 of the UN Manual of test and criteria may be carried on board an aircraft.

These restrictions are set out in the 2009/2010 Edition of the ICAO Technical Instruction for the Safe Transport of Dangerous Goods by Air and the 50th Edition (2009) of the IATA Dangerous Goods Regulations (DGR)

Subsection of the International Air Transport Association (IATA) Regulations States:

“Lithium-ion batteries exceeding a watt-hour rating of 100Wh but not exceeding 160Wh may be carried as spare batteries in carry-on baggage, or in equipment in either checked or carry-on baggage. No more than two individually protected spare batteries per person may be carried.”

The batteries used for the NIPPY have passed the UN tests and they are rated at 116 Watt hours, so they are permitted with the above restriction.

What should I tell my airline?

If you are travelling by air, it is best to tell the airline that you are travelling with a ventilator and batteries at the time of booking the flight. This gives them plenty of time to gather information about your equipment. They will not allow this type of equipment on board unless they are satisfied that it is completely safe.

There are no safety issues regarding air travel with these ventilators, but the airline need to be able to show that they checked.Your airline may want to know about the type of batteries you plan to take on board.

Your airline may want to know about the type of batteries you plan to take on board.

  • They are Lithium ion
  • The nominal voltage is 18.5 volts
  • The capacity is 116 Watt-hours
  • Each battery contains the equivalent of 10.2 grams of lithium
  • They are sealed
  • They cannot leak or spill.

Copies of the manufacturer’s safety data sheet are available to the airline from B&D Electromedical.

Should I check my ventilator into the hold?

We would advise strongly that you always carry your NIPPY onto a plane as cabin baggage even if you will not be using the ventilator during the flight.

Can I use my NIPPY during the flight?

The NIPPY 3+, Junior+, ST+ and S+ comply with RTCA/DO-160, Section 21, conducted emissions 150kHz – 152MHz and radiated emissions 100Mhz – 6GHz to category M limits and are therefore considered to be FAA compliant.

NIPPY Clearway FAQs

Can the same mechanical insufflator–exsufflator be used with different patients?

The device should be cleaned between patients and each patient should have a single-use circuit and filter; settings should be checked prior to commencement of treatment. A high-efficiency bacterial filter should be placed between the patient circuit and device. If you are treating a patient with suspected H1N1, a filter should be placed at the device end and also at the distal end of the circuit before the interface to double filter and protect the device.

The device should not be taken from dirty to clean areas as defined by local infection control policy.

How can I be sure that my patient is receiving the settings I have programmed?

The NIPPY Clearway is an extremely effective and accurate device. Digital settings ensure accurate titration and setting of pressures. The device also measures and monitors pressure at the patient end via the external pressure line.

How many times a day should MI-E be used?

MI–E can be used as many times during a 24-hour period as required to clear your patient’s secretions. However it is important to remember that prolonged coughing does induce fatigue, so ensure that you allow adequate rest periods.

Does MI-E negate the need for suctioning?

Using MI–E does not necessarily negate the need for suctioning to clear secretions, especially when initially using the technique, due to the success of the therapy. Suction equipment must always be available when treating patients with MI-E.

Should the NIPPY Clearway be used if there are no secretions present?

If it is considered that there is an area of collapse and/or consolidation on chest x-ray, combined with a patient who has an ineffective cough, MI-E can be indicated.

Patients who have a device at home can use it daily to ensure that there are no secretions present. Additionally, the NIPPY Clearway can be used to provide a stretch to the chest wall and used as a method of IPPB.

Are there any suggestions for community use and training?

It may be advisable within the community to have a programmed mode to enable use by only one carer. The settings can be titrated and set and then locked before discharging the patient, ensuring safe and accurate treatment within the community setting. There are competency documents available for carers and clinicians.

What information should patients go home with?

The patient and carers should be trained as per the competency guidelines. The patient should always have a written or photocopied document of their settings. The patient or carer can then check the settings against the record. You may want to give the patient some indication of the changes in settings that may be required for when they are unwell.

How often does the tubing in circuits need replacing?

Manufacturers’ recommendations are that tubing can be used for up to 7 days.

However, in the community setting, for single-patient use, local infection control policies may be adopted.

Can I use a circuit without a pressure line?

The NIPPY Clearway is designed to be used with a pressure line to ensure that accurate pressure measurements are delivered to your patient, which enhances performance. Not using a pressure line would cause the performance and accuracy to be reduced.

Can we use AB filters that are different?

Yes, but the resistance of the filter should be checked to ensure that the device and the patient are protected and that the performance is not affected. Filters should be within resistance levels of 0.4 mbar at 30LPM and 0.7 mbar at 60LPM.

Can I entrain oxygen into the circuit when using the NIPPY Clearway?

Yes. The NIPPY Clearway has been designed to be used with low pressure oxygen; it is possible to entrain up to 15 l/min of oxygen into the device. We recommend that this is done distally, at the patient end of the circuit.

Is it possible to use nebulisers when using the NIPPY Clearway?

Yes, it is possible to entrain nebulisers into the circuit for patients using the NIPPY Clearway. We recommend you entrain the nebuliser at the patient end after the AB filter, to ensure that the machine is protected from water or drug particles.

What options are available if my patient requires the NIPPY Clearway to be used away from the home?

For use of the NIPPY Clearway away from mains supply, you can use an external lithium-ion battery, providing up to one hour’s use, or an in-car inverter.
