Artificial Carbonated Bath TherapyOur Focus

Appropriate CO2 bath therapy would revitalize vessels of whole body.
Kaikoukai Healthcare Group has been promoting artificial carbonated bath therapy, which is effective for dramatic improvement of blood flow. For example,CO2 foot bath lowers amputation rate of patients with peripheral artery disease(PAD), and improves prognosis after amputation. CO2 whole body bath contributes to treat patients with chronic heart failure.
High-concentration CO2 bath
CO2 bath refers to hot water in which carbon dioxide gas (CO2) has been dissolved. The Hot Spring Law defines that CO2 bath means water containing 250ppm or more of carbon dioxide per liter.Especially, water with 1000 ppm or more of CO2 is called high-concentrated CO2 water, which is essential for medical treatment.
Effectiveness of CO2 bath
When you take a CO2 bath, you will find small bubbles appearing on the skin. Carbon dioxide in the bubbles will permeate into the small vessels through skin holes, which will dilate peripheral vessels and improve blood flow.
Carbonated water will result in approximately three times greater blood flow compared with plain water. It is effective not only for improving sensitivity to cold, wound healing, stiff shoulder and etc., but also to promote parasympathetic nerve dominance due to lower pulse rates.
In addition, CO2 water also draws people’s attention in terms of beauty care such as astringent effect which CO2 water shrinks or constricts the skin due to its mild acidity.

Outcome of CO2 Bath Therapy


Therapy for peripheral artery disease(PAD)
Peripheral artery disease (PAD) refers to a disease that prevents the vessels from sending sufficient nutrition and oxygen due to decreased blood flow caused by stenosis or occlusion coming from arteriosclerosis of the extremities. Chronic occlusion of large vessels of lower extremities could cause sensitivity to cold in mild cases or even necrosis in severe cases.
Therapy for peripheral artery disease(PAD)
There are many cases that continuous CO2 foot bath helps to improve blood flow and salvage amputation that is necessary in usual diagnosis.


Therapy for Chronic Heart Failure

Chronic heart failure, one of very critical complications for dialysis patients, is curable through CO2 whole body bath. CO2 water helps to dramatically decrease burden to the heart by dilating blood vessels.
Continuous CO2 bath is expected to improve chronic heart failure symptoms by recovering cardiac function.

Heart Failure Hospitalization Therapy
Nagoya Kyoritsu Hospital has a “heart failure hospitalization therapy” for dialysis patients which includes CO2 whole body bath. Two-week hospitalization is expected to lead to significant improvement in blood pressure and cardiac function.
Other than heart failure, the therapy is also expected to improve or prevent every kind of diseases such as arrhythmia.
*We offer the hospitalization therapy only to dialysis patients in Kaikoukai Healthcare Group.

High-concentration Artificial Hot Water Carbonator
Artificial CO2 water producer for medical
Facilities in Kaikoukai Healthcare Group have introduced CO2 bath therapy using high-concentration artificial water carbonators for medical use. It can produce much higher concentrated CO2 water than using home use bath tablets.
Patients soak their feet or whole body in hot water with 37-38 degrees C in 10-20 minutes.

Artificial CO2 water producer for home use

People can enjoy carbonated baths using diverse sparkling bath additives or at “super sento” or spas, or experience carbonated head spas at hair salons. Under such surroundings, carbonated bath is now familiar to many people. However, because it cannot easily be used in everyday life, its effectiveness is limited and temporal.
Sparkling nano 1300, artificial carbonated water producer for home use, enables you to easily enjoy carbonated bath and its effectiveness at home, just by connecting the shower hose with Sparkling nano 1300. Carbonated water is expected to bring its effectiveness as you use every day for a long time .
