For assistance, contact your network support team.Saskatchewan Awareness of Post Polio Society Inc.Breathing muscles require impulses from the brain to make them function.The area of the brain responsible for
this automatic breathing is the medulla.The medulla is sometimes called the "bulb", which is a
part of the brain stem (the lowest part of the brain).However, when you want to hold your breath
or take an extra deep breath, the super computer of the brain (the cerebral cortex) takes over.Chemical receptors in the chest and in the medulla detect the amount of carbon dioxide,
oxygen and hydrogen ions in tile blood.These sensors send input to the medulla which then
triggers breathing at the right time.Firing of these anterior horn
cells causes a chemical message to be sent to the breathing muscles.When the muscles get this
message, they contract, causing you to breathe.The diaphragm is shaped like an upside down bowl.It is attached to the lower ribs, the
bottom of the breastbone and the front and sides of the lower lumbar vertebrae.Thus, on inspiration (breathing in), the diaphragm moves down.The downward movement of the diaphragm and
the outward movement of the rib cage create a negative pressure within the lungs and air is
drawn in.They are active on every breath in.They lift and expand the rib cage during inspiration.These muscles are attached to the breastbone and run between the rib cartilages in a
downward and outward direction.These muscles function when you are
working harder to breathe, i.The internal
intercostals (muscles between the ribs) also work to push the air out when you are working hard.Therefore, weakness or lack of nerve supply to the abdominals not only hinders the
action of the diaphragm on inspiration, but hampers the ability to ventilate at higher than resting
levels because these muscles cannot be recruited to help out on expiration (to push the air out
quickly).Therefore you get extreme
enlargement of the motor unit (up to 7 times the normal size).Hubble hypothesis states that prominent enlargement of motor units by
axonal sprouting is not indefinitely stable and that enlarged units undergo progressive loss of the
terminal axon sprouts with time after polio.This notion was based on data that single fiber EMG
jitter linearly increased with time after polio.In other words, muscle fibers supplied by the same
nerve fibers area getting the message to contract at different times.Increased jitter may be due to poor conduction along the ends of the axonal sprouts or to
inadequate release of neurotransmitter at the neuromuscular junction.After acute polio, recovery of muscular strength can occur by terminal axonal sprouting
of surviving motor neurons, with partial or complete reinnervation of denervated muscle fibers.These enlarged motor units are undergoing a process of continuous remodelling, with constant
denervation and reinnervation after acute polio.In acute polio some anterior horn cells are lost and the muscle fibers they supply lose their
innervation.The baby nerve fibers are not very efficient and neither are the
geriatrics.In PPS, the
transmission defects are believed to be due to poor transmission along the sprouts.Another cause of poor transmission may be due to limitations in
the number or size of packages containing neurotransmitter at the motor nerve terminals.When
the water finally gets to the sprinkler, there isn't enough volume to make the water push itself
up through the sprinkler holes.If you have had bulbar polio there are several problems that this causes for breathing.Firstly, because of damage to the respiratory center in the medulla, there may be a lack of drive
to breathe, particularly when you are asleep.Secondly, there will likely be problems with the
motor nerves that supply the respiratory muscles themselves.In addition, the respiratory muscles
may themselves not be strong due to atrophy of some muscle fibers and overuse of others.In emphysema, the elastic recoil of the lung tissue is lost, hindering
expiration and causing air trapping.This causes the person to have hyperinflated lungs.As was
said previously hyperinflation causes the diaphragm to flatten.Because much of the accumulation of excess fat is deposited in close proximity to the
chest wall, severe obesity increases respiratory muscle load and markedly impairs pulmonary
function.Kyphoscoliosis causes increased work of breathing due to increased stiffness of the chest
wall and impaired muscle action due to the altered shape of the ribcage.When you have a
situation of inspiratory muscle weakness, the increased work of breathing due to changes in the
lung or chest wall may result in a relative overload being imposed on the breathing muscles.However, because they must contract repetitively, they have no
opportunity to rest and may become fatigued or injured under conditions of overload.Because of
the vital fiction of these muscles, care must be taken in progression of exercise because undue
fatigue could cause or exacerbate (make worse) respiratory failure.This would further
weaken the inspiratory muscles and could potentially result in an increased need for ventilator
support.How Do We Train Respiratory Muscles?Flex to do
training of the inspiratory muscles of a few patients.It is similar to
breathing through straws of progressively smaller diameters.In general, this technique has
been known to work well for those individuals who are breathing independently (no ventilator)
but become short of breath with exercise.The general idea is to start at the easiest level on the device.The number of
breaths taken and the resistance level recorded.However, at level five he was able to take only
three breaths.Flex
and was placed on oxygen at night.Do this only with the approval of a physician and the supervision of a physiotherapist
or respiratory therapist.Don't use it if you require ventilator support for prolonged periods (more than l 5 minutes)
while you are awake.Vital Capacity is defined by Sproule as "the greatest amount of air that the subject can expire
following a maximal inspiration".You are already working against an
increased load.Don't use it on a day that you feel totally exhausted.Stockton Record, serving the San Joaquin County and the Mother Lode.Must have recent Quickbooks and Excel experience.Looking for conscientious individual able to work independently in a busy CPA firm environment.Pleasant working conditions,flexible hours,permanent position.Recruiters, please don't contact this job poster.
