Microcirculation refers to the network of capillaries, the smallest of the blood vessels, which are found in all parts of the body and are the site for gas and nutrient exchange between the blood and the tissues.
Oxygen therapy works by first improving the microcirculation and cell metabolism;  this will then lead directly to improvements in organ function.  There is a direct relationship between the level of tissue oxygen tension and wound healing.

Microvascular Assessment

Transcutaneous tissue oximetry and laser doppler flowmetry are used together to assess the functioning of the microcirculation in a MicroVascular Assessment.  This is a non-invasive, painless procedure, and a very important tool; it’s used for initial assessments (prior to starting HBOT) as well as for monitoring the progress and success of hyperbaric oxygen therapy.  The results of the initial assessment will tell us whether hyperbaric oxygenation is likely to be effective, and provides a precise estimate of many sessions will be needed.

Transcutaneous tissue oximetry and laser doppler flowmetry are well understood, widely accepted and validated procedures.  When justifying the reimbursement of hyperbaric oxygen therapy the insurance agencies (in the USA) require microvascular assessment reports.  At BaroMedical, we perform complete microvascular assessments and are Canadian leaders in the use of this technology.

Electrical Stimulation | BaroMedical

When nerve is stimulated such as in people who lost the control of their muscles (i.e. stroke, brain injury, spinal cord injury) we can elicit a functional movement. Electrical stimulation is the therapy where electrical currents are delivered trhu the skin electrodes to activate muscle contractions or nerve conduction.


Services | BaroMedical

Oxygen stimulates the budding and growth of new blood vessels -a process known as angiogenesis, which further improves delivery of oxygen and nutrients, and tissue granulation. Initially, inflammation swelling and pain are reduced via vasoconstriction, while an elevated level of oxygen directly helps to initiate healing while reducing scarring.


Hyperbaric Oxygen Therapy | BaroMedical

When breathing pure oxygen at pressures higher than normal additional “hyperbaric” oxygen dissolves in the blood plasma greatly increasing the quantity of oxygen transferred to any tissue in the body. BaroMedical’s chambers are certified for operation up to 3 atmospheres for which hyperbaric oxygen therapy has been proven effective and safe in infection control and wound healing.


Wound Care with Hyperbaric Oxygen

Electrical stimulation will further promote the circulation of superoxygenated blood deeper in the wounded area and combined effect is magnified.Oxygen initiates healing from within the body by mobilizing the growth factors and preparing the wound bed for the right combination of topical wound therapy.
