Tissue oxygen delivery
Specialist teams assess organ function and physiological evidence of inadequate oxygen delivery.
Severe breathlessness, chest pain, fainting, or suspected major bleeding require emergency care. Call 911; do not wait for an outpatient appointment.
Severe anemia research & care · Scottsdale & Glendale, AZ
In exceptional cases of severe anemia, hyperbaric oxygen can provide a temporary way to increase oxygen carried in plasma.
RX-O2 offers a physician-led conversation about the evidence, your diagnosis, and the role of hyperbaric oxygen therapy in your broader care plan. Our Scottsdale and Glendale teams serve patients across the Phoenix area.
Published clinical experience supports a specialized rescue role when oxygen delivery is critically limited and transfusion cannot be given. This requires urgent hospital-led care. Explore the evidence below.
Physician-led care in Scottsdale and Glendale, serving the Phoenix area.

The starting point
Hemoglobin in red blood cells normally carries most of the oxygen delivered to tissues. Profound anemia can reduce that delivery even when a pulse oximeter appears reassuring.
Under hyperbaric conditions, more oxygen dissolves directly in plasma. In selected critical situations, this can support tissue oxygenation while the team controls bleeding, treats the cause, and supports red-cell recovery.
The clinical context matters. HBOT does not replace lost red blood cells or correct the underlying cause of anemia. Blood transfusion and other definitive treatments should be used when clinically appropriate.
Connect the research to your goals
Specialist teams assess organ function and physiological evidence of inadequate oxygen delivery.
Control of bleeding and treatment of the anemia remain central to recovery.
HBOT may serve as temporary support within a carefully monitored hospital plan.
Your goals help shape the conversation and provide a useful way to follow progress if treatment is prescribed.

Literature checked
October 20, 2026
2021 · Case report
Publication indexed in PubMed. 2021.
Read the publicationA case report described a patient with a hemoglobin level of 2.6 g/dL who declined transfusion. The patient improved during treatment that included vitamin B12 replacement and HBOT.
How to interpret it: A single case cannot isolate the HBOT contribution or predict other patients’ outcomes. Treatment of the underlying vitamin deficiency was essential.
2024 · Clinical review
Van Meter KW, et al. Frontiers in medicine. 10/08/2024.
Read the publicationA 2024 review explains the use of increased dissolved plasma oxygen as temporary support in selected severe anemia when transfusion is unavailable or cannot be given.
How to interpret it: This is specialized clinical guidance and reported experience, not evidence that routine anemia should be treated in an outpatient chamber.
The clinical rationale and successful reports support a carefully selected rescue role. The decision depends on severity, the cause of anemia, available definitive treatment, and hospital monitoring. After stabilization, your treating team can advise whether any further hyperbaric involvement is appropriate.
Plan with your care team
Provide the hospital assessment, anemia cause, hemoglobin trend, bleeding status, organ function, and treatment already underway.
Review the evidence with your treating specialist and hyperbaric clinician. Identify specific outcomes to follow, the alternatives, and the reasons HBOT may or may not be appropriate.
If treatment is prescribed, discuss the schedule, travel, costs, safety screening, and how progress will be reviewed. A published study schedule does not determine an individual prescription.
Your consultation is an opportunity to ask about expected benefits, treatment experience, scheduling, costs, and follow-up. We review suitability with you and coordinate with your treating clinicians when appropriate.
The RX-O2 difference
Medical Director Marvin A. Borsand, DO, FACOS, FACCS, HCC, leads clinical oversight. A licensed medical provider reviews suitability and prescribes treatment when appropriate.
Our clinics use FDA-cleared hard-shell chambers. You breathe 100% medical oxygen through a mask or hood while the chamber is pressurized with air.
NHSA-certified hyperbaric technicians explain the visit and monitor treatment. Tell us about ear pressure, positioning, mobility, or confinement concerns before you arrive.
Before your visit
This page concerns exceptional severe anemia, not routine iron deficiency. Diagnosis and appropriate iron or other treatment should be directed by your clinician.
Its immediate purpose is to increase dissolved oxygen, not to create red blood cells. The underlying cause must be treated.
No. Critically low oxygen delivery is a medical emergency. A hospital team must direct evaluation and treatment.
RX-O2 has clinics in Scottsdale and Glendale. Bring your records or ask your provider to send a referral so that the team can review your circumstances and explain whether an outpatient consultation is appropriate.
Local care, two Valley locations
Looking for a hyperbaric consultation near Phoenix? RX-O2 offers two locations for patients across the Valley. Call the clinic closest to you for appointment availability and help planning repeat visits.
An East Valley option for patients in Scottsdale, Paradise Valley, Fountain Hills, and nearby communities.
A West Valley option for patients in Glendale, Peoria, Phoenix, and nearby communities.
After urgent medical needs have been addressed, ask your treating team whether an outpatient hyperbaric consultation has a role.
