Veterinary Oxygen Therapy Resource Hub

Oxygen therapy is a cornerstone of veterinary critical care. Whether managing post-surgical recovery, respiratory distress, or chronic conditions, understanding oxygen delivery systems and best practices helps veterinary teams provide better patient outcomes.

Oxygen concentrators produce oxygen from ambient air on demand, while tanks store a finite supply that needs refilling or exchange. Concentrators suit clinics seeking a standalone supply or backup for central oxygen; tanks remain useful for mobile work and power outage backup. Compare flow requirements, patient volume, space and operating costs before choosing a source.

Frequently Asked Questions

Most veterinary ICU patients benefit from an FiO2 of 40-60%. Concentrations above 60% should be used cautiously and for limited durations due to the risk of oxygen toxicity. Modern oxygen cages allow precise FiO2 control to maintain therapeutic levels.

Oxygen concentrators offer lower upfront cost, no tank storage requirements, and continuous supply. Central oxygen systems provide higher flow rates suitable for multiple patients simultaneously. The best choice depends on patient volume, space, and budget considerations.

Traditional oxygen cages use soda lime canisters to absorb CO2. Soda lime-free systems like AERAFLOW technology use controlled airflow engineering to manage CO2 levels without chemical absorbents, reducing maintenance costs and eliminating chemical waste.

Oxygen therapy should be initiated when SpO2 drops below 94% or when clinical signs of respiratory distress are present, including increased respiratory rate, cyanosis, open-mouth breathing, or orthopnea. Early intervention generally produces better clinical outcomes.
