ENVIRONMENT..
     Principle of low air loss
             therapy

“ Low Air Loss therapy works on the
   principles of Fluid Dynamics, Heat
  Transfer and Phase Change to create
   a favourable microclimate for that
    part of a patient’s skin in contact
    with and occluded by the support
     surface. This microclimate has
    similar temperature and humidity
  characteristics to those to which the
   non occluded parts of the patient’s
            skin are exposed “
              Controlled
             Environment

 WHY ??
 The skin of apressure can be more
  resistant to
                patient
                        ulcers if its
    surrounding environment is
    controlled

 At the areas of contact with the
  support surface, excess moisture
    and temperature weaken the skin
    and increase the level of any friction
    or shear loads it encounters
      The skin not occluded from the normal room
      environment
          • correct moisture concentration
          • correct temperature



•Insensible moisture loss and
sweat
   •Constantly remove excess
   body heat.
   •Maintains the proper skin
   temperature and integrity.
Skin occluded by a Moisture Vapour Impermeable Surface
     becomes over-hydrated & over-heated
            Why excess
             moisture?
 Insensible moisture vapour (IMV)
 Oedema (local or generalised)
 Burns
 Highly exuding wounds
 Incontinence
    Over-hydration & over-heating of the skin has some
                  significant effects...

   The sweat rate doubles for every 1.5’c
    increase in skin temp..

   The potential for increased body
    temperature. If excess heat cannot be
    removed, the thermal regulation of the
    patient may be compromised..
    Over-hydration & over-heating of the skin has some
                  significant effects...

   The shear and friction forces are doubled
    when the skin becomes over-hydrated..

   The stratum corneum is 25 times weaker…
    rise in Ph, increase in micro-organisms,
    reduces resistance of external water by
    75%…
How does low air loss
    therapy work?
 Low Air Loss -
Pressure Reducing
         Low air loss mattresses
         consist of a series of
         vapour-permeable sacks,
         with pinholes in the
         upper most side, through
         which air is lost. The air
         sacks are inflated by a
         rotary pump driven by an
         electric motor
         They help minimise
         maceration and reduce
         hypothermia

               moisture vapour passes through the cover
                and is carried away by the air flow between
                the cells & cover to the room environment


• fluids flow from a high
concentration to a low

• heat flows from a high

                pinholes in the upper

                air is lost.

                They maximise the area

            Repositioning

 Frequency of repositioning should be
    based on individual need and
    consideration of the surface upon
    which the patient is sitting or lying.

 Pressure areas should be carefully
    monitored to establish an
    appropriate time for each patient.
