EWOT - Everything you need to know

EWOT Demo by Dr. Sircus

EWOT is the act of breathing higher concentrations of oxygen during exercise. In the past, simple masks and nasal cannulas connected directly to an oxygen concentrator were the best methods. However, oxygen concentrators only produce 10 Liters Per Minute (LPM) at maximum. When you exercise, you can easily breathe 60-70+ LPM. This means you are "blending" the 93% pure oxygen from the concentrator within the mask or around the cannula. Since these oxygen delivery products allow room air in, you're not coming close to getting the high purity and flow required. This problem is solved with EWOT.

EWOT uses an oxygen concentrator to fill a large medical grade bag that holds 900 liters of oxygen. A high-flow mask is attached to that bag. Now every breath you take is 93% oxygen with NO room air. The EWOT mask does NOT allow any room air inside. Only the oxygen in the bag is inhaled as a valve in the mask opens then, as you exhale, CO2 goes out through the CO2 port on the mask. The mask included with EWOT is the highest flow, non-restricted mask on the market. It's like breathing without one, it's that good.

The EWOT Therapy (shown at left) includes everything you need except an oxygen concentrator and fitness equipment. You can use your own oxygen concentrator or pick one of the three we offer. Any oxygen concentrator will work with the BASIC Therapy packages listed above. However, keep in mind that higher LPM (liters per minute) will fill the bag faster. A 5 LPM unit will take about three hours to fill and 10 LPM will take half that time. If you have access to your own concentrator, try to get a 10 LPM.  You can pick any one of our three concentrators before you add to cart, or choose "none" if you have your own. You can utilize as many oxygen concentrators at the same time to fill the bag faster. Simply order the EWOT Multi-Port separately. 

The second package is EWOT Altitude (switch between rich and low oxygen with adjustable hypoxic purity). This system is the BASIC Therapy package above PLUS a smaller bag, oxygen purity switch and a 10 LPM Altitude Tech concentrator is added. The system allows the user to switch between any purity (simulating sea level to 25,000 feet) and 93% oxygen. The Altitude system requires this concentrator to accommodate the small air bag that provides the adjustable oxygen levels.

Why allow switching of any purity?

Many athletes are highly conditioned and when they breathe high purity O2, they cannot get their heart rate over 110 Beats Per Minute (BPM). This is critical to dilate the arteries to maximum level and assist oxygen in reaching deep oxygen-deprived tissues. The process is to workout at a normal pace for approximately 3 minutes with 93% O2, then switch to altitude (e.g., 14% purity which is approx 9000 feet) and sprint for 30 seconds followed by an immediate switch to 93% for another 30 seconds while sprinting. Then resume to a normal pace and BPM for 3 minutes, and repeat the cycle 3-4 times. This is also very beneficial to anyone (athlete or not) as it will accelerate the benefits.


 sets ours apart from other systems?

EWOT offers the patent pending Automatic Positive Pressure System (APPS) which slowly pushes oxygen out to the mask just like an oxygen concentrator does. This is accomplished with the two white horizontal ribs shown in photos. They are attached after the bag is filled. This increases the efficiency of delivery regardless of how much oxygen is left in the bag. This does not interfere with the normal inhalation reflex. It is calibrated to make breathing as normal as possible. No other system offers this feature. In addition, the oxygen hose in other systems will constantly get in the way as your hands or arms move. We include a two-way Velcro® Strap that attaches to your fitness equipment to solve this problem. The strap has dual rotating adjustable loops so your oxygen hose can be positioned anywhere you desire. It guides the hose without restricting its movement while the other half of the strap remains fixed.


About our Masks:

There are two package types, Therapy and ALTITUDE, and each package can be ordered with or without the Medical Grade Mask to offer four different options. If you are a clinic and/or have multiple users, you will need the system with the Medical Grade Mask (BLUE). The BLUE mask can withstand repeated sanitization and sterilization procedures. The single-user mask is our CLEAR mask.

Which mask do I need?

We offer two masks in three different sizes. The CLEAR mask is included with our EWOT Therapy & ALTITUDE. It's a single-user mask. The BLUE mask is our Medical Grade mask.  The BLUE mask is ideal for multiple user purchases such as clinics or multi-user families. It will withstand long term sanitization procedures as well as sterilization (including autoclave). Green valves in both masks cannot be autoclaved and are for single-user use. Additional valves can be ordered by clicking here
