I would like to relate an experimental protocol recently developed by one of our younger ( and brighter ) staff members. He originated the idea and assembled all parts into a working model in less than two days-------after his original inspiration. The original problem manifested as a result of our fruitless search for some effective procedure for attacking the bilateral form of those bacterial pneumonias which have proved non-responsive to all of the antibiotic protocols. This challenge has been especially dear to our hearts since one of our engineers lost his 47 year old wife ( a wonderful school teacher ), at the age of 47--------nine years ago.

We have used this system on 3 volunteers----and this only----within the past four weeks. However, we have been absolutely astounded by the results. One 75 year old asthma sufferer, unable to gain more than momentary relief during the past 8 years, was able to dispense with his very labor-intensive ( unbelievably costly ) hospice-assisted protocols............18 days after undertaking this protocol. We now suspect that his asthma was the result of some form of secondary bacterial pathogen......this because of the speed and degree of his recovery.

Another of our volunteers ( 71 years ), was afflicted with a sub-clinical bronchial infection which was non-responsive to any protocol including Rife Beam Ray Therapy. He has improved by at least 75% within the past 21 days and shows every indication of complete resolution within the next week or so. This volunteer was in perfect health in every other way -- except for the bronchial disorder ( complicated by a minor but persistent postnasal drainage ).

The third volunteer was an 81 year old male, completely non-responsive to all therapies for bilateral pneumonia of a bacterial nature. This condition had persisted for 6 months and he was approaching a moribund state, and very rapidly. 24 hours after beginning this protocol, he encountered a very serious crisis evolving from a major Herxheimer's Reaction. Pustule formation was so rapid and intense, 100% oxygen support was required -- and the treatment protocol was suspended for two days while the volunteer's condition was stabilized. Two days after resumption of the Oxygen-Colloidal Silver protocol, no supporting oxygen therapy was required as the subject was fully able to breathe unassisted. The volume of sputum/pus fluid was massive. Excepting a very sore chest area ( from prolonged coughing ) the volunteer was much improved. Within five days he became very alert and began to overcome his narcoleptic tendencies. Within ten days he became ambulatory again. Within 15 days his lungs were unobstructed enough he could breathe fully, with no audio evidence of fluid presence in the pulmonary tract. Yesterday ( the 21st day ) his lungs checked out to be 90% clear, with only one tiny spot in the lower left quadrant of the left lung. His MD pulmonary specialist is in a state of "shock" over the developments. His analysis is that this is the most pronounced case of "spontaneous remission" in his 30 years of practice. No one has informed the MD of our experimental protocols used on this volunteer. Our volunteer's immediate family is so irate over the fact that his allopathic pulmonary "team" was totally unable to reverse his decline toward immediate life-departure ( the crisis management team did offer to place him on 100% life support until clinical death ), they wanted to instigate some form of legal action. We reminded them of their earlier agreement with us, that regardless of the outcome of our experimental protocol, "neither the procedural result nor the protocol itself, would be broached with the volunteer's allopathic counsel." Additionally, based upon the anecdotal nature of this one case, there is no way to prove efficacy.


The protocol consists simply of using a nebulizing system constructed from a conventional artist's airbrush assembly, with modified pneumatic plumbing facilitating its connection to a pressure-regulated pure oxygen supply. The airbrush mechanism was chosen because it provides an exceptionally economical means of furnishing a very small particle aerosol fog ( in the 4 micron vicinity ). Using a very simple adapter from the airbrush pressure regulator, attached to the oxygen supply hose coupling, plus a standard welding system size oxygen fitting (female), the assembly is connected directly to the oxygen port outlet from either a small medical-type oxygen bottle -- or a standard welding system oxygen bottle outlet ( they both contain the same oxygen purity ).

Using the small fluid-supply bottle which comes in the airbrush kit and filling the supply bottle approximately 3/4ths full ( about 1/2 ounce ) of 5 ppm CS, we were ready to start. The oxygen system ( we used two-stage regulators ) was SLOWLY set for constant regulation at 35 psi, at which point the system was ready for use. We placed the airbrush in the hand of the volunteer, who in turn pressed the push-valve button when they wanted to direct the oxygen/colloidal silver fog mixture into their mouth. The volunteer then inhaled it directly into the pulmonary system. At the end of each inhalation, the volunteer simply released the pressure on the button and shortly exhaled. This procedure was repeated until the entire contents of the airbrush supply bottle was below the intake point of the supply-siphon tube ( about 50-75 breaths total ). This protocol was employed twice daily (24 hours) for the entire duration of these researches.

As a word of encouragement for those unable to afford $680.00 for a hospital-type nebulizer, the total cost of our assembly, less the oxygen bottle and regulator, was less than $20.00. Additionally, our particle size was BETTER from the $10.85 Taiwanese bargain-brush than from our $680.00 hospital-grade nebulizer ( at least our measurements indicated so ). I will also tell you where you can purchase these airbrush kits . We purchased 20 units and outfitted them, and have given them away to very needy Experimental Volunteers of a charity nature. Within the next 8 weeks, we should have some useable "raw" data, which I will attempt to share with interested list members.

My excitement over this exceptionally low-cost----and promising protocol, has been keeping me awake nights......lately!

The following is a list of the components required for enabling the protocol we used in the experimental researches I outlined above:

The airbrush kit we used was obtained from a mail-order concern specializing in myriad hardware/electrical/hand-tool items. Their quality is toward the low-end industrial, but quite adequate for the home/hobby user. Our machine shop/prototype builders have used them for years. The company is Harbor Freight, located in Camarillo, California. They now have outlets in one or two other cities. We obtained our airbrush kits from the Fort Worth, Texas store (we are located in Fort Worth). The stock number is #6131. Our purchasing person informed me this item cost us less than $10.00 each, and the last 20 purchased cost less than $8.00. As of last Wednesday, this store still had some of these units. Included in the kit are two liquid supply bottles ( one 1/2 and one 1 oz ), one air hose which couples between the pressure regulator and the airbrush assembly, one air pressure regulator; and the airbrush assembly itself. The additional parts required are for a hose assembly which facilitates coupling the input side of the air pressure regulator with the external oxygen supply used to power the nebulizer.

Please note that any similiar airbrush kit can be converted... Including this one at Harbor Freight:

NOTE: PURCHASE BRASS FITTINGS ONLY. Oxygen is the preeminent combustion supporter.

All of the additional components can be obtained from any commercial outlet stocking pneumatic system parts.


One 1/4" Compression X 1/8" Male NPT fitting
This is very important, for without it you cannot connect the O2 hose to the airbrush pressure regulator.

One 1/4" Barb X 1/8" NPTF Fitting

One 1/4" X 9/16 RH Oxygen Fitting
This will have a barb fitting on one end and the female coupling on the other.

Approximately 4 feet of any good 1/4 I.D. 200+ PSI air hose.
Tell the clerk you are going to use oxygen in the hose.

Any small screw or compression type clamp to secure the hose to the barb fitting.

Any small clamp to secure the hose to the airbrush assembly

An oxygen bottle or arc welding oxygen container/bottle ( about 1/2 - 1 cubic foot capacity )

A two-stage oxygen regulator
[ We have found that a single-stage regulator is sufficient ]


Assemble the parts as follows:

1. Screw the Compression fitting into the 1/4" Barb X 1/8" Male NPT fitting.

Do not worry, only one end of the Compression fitting is compatible with the Barb fitting.

2. Insert the barb end of this fitting assembly into the air hose.

Push the hose on until it is jammed against the shoulder of the fitting. Any small screw or compression-type clamp may be used to add security to the hose/fitting end.

3. Insert the barb end of the Oxygen fitting into the remaining hose end and secure with any satisfactory clamp.

Your assembly is now complete.

Next, carefully screw the exposed male end of the Compression fitting into the bottom of the airbrush pressure regulator. Now connect the small-diameter airline between the airbrush assembly and the pressure regulator ( it is foolproof, as there is nowhere else this tiny hose can connect).

Select the small fluid-supply bottle and fill approximately 75-80% of capacity with 5-10 ppm Colloidal Silver and insert the angled tip assembly into the bottom of the airbrush assembly. You are now ready to connect to your O2 supply and operate.

Connect the two-stage oxygen regulator to the oxygen bottle. Then, connect the 9/16" Oxygen-fitting to the oxygen outlet from the Two-stage regulator (also foolproof, as there is nowhere else to connect).

SLOWLY open the oxygen control knob on the oxygen regulator and set the inlet pressure to your nebulizer assembly [ this is the adjustment knob/handle on the oxygen regulator itself ] to a maximum of 35 Pounds Per Square Inch ( PSI ). Next, screw the AIRBRUSH air pressure regulator control knob (the tiny knob on top of the air pressure regulator ) all the way closed.. Now, open the control knob about 2 and one-half turns [ experimenting with this control can yield excellent results for a variety of uses, but always pay careful attention to create the finest mist possible when using the unit as a nebulizer ]. Next, trigger the control button on the Airbrush head until you see a fine fog each time you press down on the button. The mist is so fine, you may have to hold it against a dark back ground to see it. You are now ready to go.

Our best results were obtained by the volunteer inserting the discharge nozzle about 1 inch inside their OPEN mouth and breathing deep-- and long-- on each inhalation; holding the breath for a count of 3 or 4 and then executing a complete exhalation. Ideally, there should be about 1/4" circular clearance around the airbrush head ( while inside the mouth ), as this provides the optimum venturi action for incorporating air with the oxygen. In acute circumstances, the volunteer can close his/her mouth completely around the nozzle and breathe 100% oxygen-- this works great.

Remember: NEVER USE PURE OXYGEN NEAR OPEN FLAMES OR COMBUSTIBLE MATERIALS. To do so would make this protocol quite irrelevant!

Any serviceable airbrush assembly could be used. However, try to obtain one that will yield the smallest size particle possible.


I failed to include a suggestion which some may find of critical importance. If you do not have immediate access to an O2 supply, and encounter an EMERGENCY experiment, you can connect into any available air compressor outlet (however, you may have to change out the Compressor-side fitting). To be safe, let the air compressor charge to 35 psi and disconnect it from the power grid. There will be ample air pressure to execute your protocol. The airbrush will function quite well to below 20 psi. Although your air-supply may be contaminated....the alternative to getting CS into the VOLUNTEER animal/pet may be a much more grave situation.

We had excellent, but less spectacular results using compressed air as the driving medium in some animal experiments in 1998, when addressing some serious pulmonary compromises involving felines.

There is a POSSIBLE modification that may be required. It involves the 1/4 inch Compression X 1\8 inch NPT
pipe fitting and the Pressure Regulator of the Airbrush system. There is a synthetic rubber "O-Ring" seal located in the bottom of the disc-shaped regulator assembly [ you will see this o-ring when you obtain the parts, and purchasing an extra one at a hardware store is a simple task ]. Sometimes, the regulator-end of the hose fitting does not bottom properly against the "O-Ring", thus allowing a small oxygen leak at this point. The solution is to obtain a second "O-Ring" ( from any hardware store ) and install it on top of the first "O-ring". This will solve the problem ( take the old "O-ring" with you for proper size gauging).

Also, there is a simple solution to this which both reduces the parts count and improves the system operation. This is, to obtain, from Harbor Freight, a little 1/4" Air Brush Couple part # P-1655 (cost about $1.00). This fitting is actually a reducing coupling which allows the elimination, entirely, of the air brush pressure regulator (which is furnished as a part of the purchased assembly package) and facilitates connecting the small air brush inlet hose - directly to the O2 or air source. This procedure eliminates all of the air sealing problems surrounding the original assembly usage

One other point; it is not necessary to run at 35 psi oxygen pressure for satisfactory results. In fact, many prefer to run with
20 to 25 psi. 35 is the UPPER LIMIT of operation, for satisfactory use of this system.

A word of caution for persons contemplating constructing any form of "home-built" device; a very important consideration is TRANSPORT FLUID (O2 or air) ATOMIZED PARTICLE SIZE. The larger the particle, the more likely for it to agglomerate (attach to) with its neighbor. For this reason I would caution all Experimentors NOT TO INHALE either air or O2 as transporter using conventional throat atomizers. Besides causing excessive and uncomfortable coughing, the particles are, simply, too large to yield any reasonable degree of penetration into the deeper portions of the pulmonary network.

Please remember these are RESEARCH protocols and are not intended to be used as any form of medical practice.
