HAPP100 : Frequently Asked Questions




Will my medical conditions prevent me using a HAPP ?

With spinal injury and even with tracheotomy ventilation, users have found no problem producing sufficient pressure by simply using their cheeks. Like all severe conditions the precise limitations are subtly different between individuals so no guarantee could reasonably be given. Testing is strongly advisable, also see below for tests you can do at home to ascertain if a breath controller is a possible solution for you.

With conditions such a MND it is common that the ability to blow is seriously compromised yet suck remains reasonably strong by comparison. Usually the special sensitivity adjustments configurable within the HAPP by the user or by Celtic Magic prior to dispatch can compensate for this disparity.


How much do I need to blow & suck ?

The HAPP100 has a very sensitive pressure transducer at its heart.   It resolves pressure down to better than +/- 0.002psi, which is better then any other regular Sip & Puff device we know of.

To use a HAPP100 the user needs to be able to blow and suck at 400Pa or around 0.06psi.  In  practice, it is easier to think of this as how high can you suck water up a straw, or how deep can the straw be under the water and you can still blow bubbles.  400Pa is about 2" or 50mm of water depth.   Try at home to see if you can achieve this.

In addition any user has to be able to hold that pressure for about three seconds. (not blowing bubbles for three seconds - just hold that static pressure)


Anything else I need to be able to do to use a HAPP ?

As the HAPP is controlled by mouth pressure it is important that any intended user can seal their lips around the small 3mm control pipe. Any weakness to seal reliably will compromise the practicalities of using a breath-controlled device.



Can I use a HAPP100 for Emergency calling 

A HAPP100 can certainly be used to call for assistance and is very good at that especially the HAPP100/B model that easily can connect to other support equipment.

However it can only be as reliable as the PC/Mac operating system it is connected to which are reliable these days but are not rated for critical life support.

Most assistive aids are similar to this in that they are not technically rated for true life dependant calls for assistance, but an assessment of risk needs to be made between...

a) Is this the most practical way for a user to call for help
vs
b) The chance of a simultaneous complete failure of the PC & HAPP100
vs
c) The chance that such a call is truly threatening to life or just very inconvenient 

This is an assessment the user / healthcare professional has to judge as acceptable or not for an individuals circumstances.   In the case of a healthcare professional any such decision should be documented as a formal risk assessment having assessed reasonable alternative means of raising an alarm, if any.



Does the HAPP work with an iPad?

Unfortunately no, it doesn't.  The iPad is designed around a touch screen, and does not have a mouse interface. 


Does the HAPP comply with legislation?

The HAPP100 is CE compliant and with FCC standards in the USA.   It is a Class 1 medical device (non sterile and non measuring).  Outside of Europe legislation varies and even differs within different local areas, states & organisations so please check with your local legislators for your particular use before purchase.


Which model is right for me?

Q1.  Do you have reasonable movement of your neck & head?

Yes: Use a good quality web camera for use with any HAPP model in Camera Mode 
No:   Use a standard model HAPP on its own (it's just a bit slower)

Q2.  Can you operate a button with some convenient part of your body?

Yes: Consider a HAPP/A model as it will make things faster for you

Q3.  Do you have or plan to have another assistive aid with 3.5mm jack inputs, perhaps to control your TV, answer a phone or control your environment?

Yes: Consider a HAPP/B model
