Oxygen therapy
venous stasis ulcers and devitalised tissues in the lower limbs
District Madeyski Hyperbaric Chamber 2003
Oxygen therapy
We can say that oxygen therapy has been the evolution of
Hyperbaric therapy used in the last 30 years to treat
different pathologies related to deficiencies of circulation
and infection.
District Madeyski Hyperbaric Chamber 2003
Principles on which hyperbaric oxygen therapy is based
The Oxygen works by contact and because dissolved in the blood ( a modest increase is linked to the haemoglobin but a considerable
increase is dissolved in the plasma)
District Madeyski Hyperbaric Chamber 2003
Principles on which hyperbaric oxygen therapy is based
Remember that in the Hyperbaric Chamber the atmospheric pressure is increased while the
partial pressure of the oxygen remains invariable
District Madeyski Hyperbaric Chamber 2003
ULCERS AND DEVITALISED TISSUES
IN THE LOWER LIMBS
1) Venous stasis ulcers
2) Arterial ulcers
3) Traumatic ulcers
4) Collagenopatic ulcers
5) Diabetic ulcers
District Madeyski Hyperbaric Chamber 2003
THE THERAPIES
1) Medical therapy 2) Surgical therapy 3) Plastic surgery 4) Hyperbaric Chamber Therapy
District Madeyski Hyperbaric Chamber 2003
Advantages Disadvantages
increase oxygen dissolved in the plasma
-Not for all people
-Cardiac,vestibular or cochlear tract, psychological problems
-Limited availably
-Problems with travelling distances
-No Availably of bed places
-Social and public costs
Hyperbaric Chamber
District Madeyski Hyperbaric Chamber 2003
so called since resembling the Hyperbaric Chamber used by most
important Medical Centres.
The Madeyski District Hyperbaric Chamber District Normobaric Chamber
District Madeyski Hyperbaric Chamber 2003
Advantages Disadvantages
increased oxygen in contact with the lesion
Minor increase by oxygen dissolved in the plasma
Rilevant Advantage:
No local or general contraindication.
The Madeyski District Hyperbaric Chamber District Normobaric Chamber
Advantages:1) Patient satisfaction
2) Simple use and appreciation by paramedic staff
3) The lack of general contraindications.
4) The lack of local contraindications
5) Its reduced dimensions and easiness of transport
6) Its agreeable shape
7) Easily availability
8) The low cost of the device and its maintenance
9) Staff's quick training
10) Documented effectiveness

DIFFERENCES BETWEEN
THE HYPERBARIC CHAMBER AND
THE DISTRICT HYPERBARIC CHAMBER
District Madeyski Hyperbaric Chamber 2003
Differences between the hyperbaric chamber and the district hyperbaric chamber
District Madeyski Hyperbaric Chamber 2003
Whilst in the hyperbaric chamber the treatment is through contact and dissolved oxygen in the plasma, in the district normobaric chamber the increase of dissolved oxygen in the plasma is lost
This missing effect is compensated by the increased oxygen concentration in the district normobaric chamberThe concentration, in fact, reaches 95% or a set value which therefore corresponds to 4 times the value found in the hyperbaric chamber.
Differences between the hyperbaric chamber and the district hyperbaric chamber

But if an associated breathing in an oxygen mask is performed , the
dissolved oxygen quota in the plasma increases without reaching the values due to hyperbarism.

Times of application of District hyperbaric chamber
Are different according to the pathology and the local situation
Similarly the number of days in which the therapy is applied is variable and linked to the pathology and to others
contingent factors
District Madeyski Hyperbaric Chamber 2003
Times of application of District hyperbaric chamber
The average therapy is applied for the duration of one hour, twice a day
Similarly the number of days in which the therapy is applied is variable and linked to the pathology and to others
contingent factors
District Madeyski Hyperbaric Chamber 2003
Past case histories
141 patients treated with chamber in an experimental period
During this period the chamber was not the definitive one
District Madeyski Hyperbaric Chamber 2003
Present experience
196 patients so divided:
1) 150 venous stasis ulcers
2) 12 Arterial ulcers
3) 5 Traumatic ulcers
4) 3 Collagenopatic ulcers
5) 22 Diabetic ulcers
6) 1 oncocarbide Ulcers
7) 13 patients with epidermic transplants
District Madeyski Hyperbaric Chamber 2003
Results Considerations for a correct evaluation
Since we are dealing with a chronic syndrome one can't reach a definitive recovery if the ethiology is not corrected identified.
District Madeyski Hyperbaric chamber 2003
Results Considerations for a correct evaluation
Sometimes,in subjects affected by peculiar
pathology, a definitive recovery can not be reached.

Results1) Decrease of the secretions
2) Improvement of subjective sinthomatolgy
3) Improvement of objective sinthomatology
4) Cleaning of the lesions
5) Reduction of the diameters
6) Evidence of the granulation tissues since the third day of application
7) A positive result of the transplants expecially if Reverdin method is used
District Madeyski Hyperbaric Chamber 2003
The future …
1)Portable device of contained cost for the house therapy
2) Nebulising for introduction of drugs:
- vaso dilatators –- healing
- for diabetic ulcers 3) Platelets concentrated
District Madeyski Hyperbaric Chamber 2003
Conclusions The use of the Hyperbaric Chamber
with a partial increased oxygen pressure is a very useful tool, at a
low-cost and without contraindications for a large number of subjects with a
large amount of devitalised or not very vital tissues ,due to local or
general causes in the inferior limbs
