Oxygen Use in Veterinary Clinics: A Technical Overview
Reliable access to medical-grade oxygen is critical in modern veterinary practice, underpinning everything from anaesthesia to critical care. Yet traditional reliance on cylinders or bulk deliveries introduces risks—supply disruptions, escalating costs, and logistical complexity.
On-site oxygen generation offers a transformative alternative. By producing high-purity oxygen directly within the clinic, veterinary practices can enhance operational efficiency, ensure continuity of care, and future-proof their infrastructure. This article explores the technical, financial, and operational advantages of oxygen generation systems—and why partnering with an experienced integrator like EHL using AirSep technology is key to long-term success.
Oxygen is a cornerstone of veterinary medicine, used across multiple clinical functions:
1. Anaesthesia Delivery
- Oxygen acts as the carrier gas for inhalant anaesthetics (isoflurane, sevoflurane).
- Stable, uninterrupted flow is essential for precise anaesthetic depth control.
2. Critical Care & Emergency Medicine
- Oxygen therapy supports patients with respiratory distress, trauma, or cardiac compromise.
- Delivery methods include cages, nasal cannulas, masks, and ventilators.
3. Surgical Procedures
- High flow rates are required for extended procedures.
- System reliability is critical to maintain patient safety during operations.
4. Diagnostic & Recovery Support
- Supplemental oxygen improves recovery outcomes and reduces complications.
Given this broad reliance, any interruption in supply can directly impact patient outcomes and clinic operations.
What is On-Site Oxygen Generation?
Most modern systems use Pressure Swing Adsorption (PSA) or Vacuum Pressure Swing Adsorption (VPSA) technology.
How PSA Works:
- Ambient air (~78% nitrogen, ~21% oxygen) is compressed.
- Air passes through molecular sieves (zeolite material).
- Nitrogen is adsorbed, leaving oxygen enriched gas.
- Output oxygen purity typically ranges from 90–95%, fully suitable for veterinary use.
AirSep systems, globally recognised in the medical and industrial sectors, are engineered for reliability, efficiency, and continuous operation.
Cost Benefits: Moving from OPEX to CAPEX Efficiency
1. Elimination of Cylinder Rental & Refilling Costs
Traditional supply involves:
- Cylinder rental fees
- Delivery charges
- Handling and storage costs
On-site generation replaces these with:
- Power consumption
- Routine maintenance
2. Long-Term ROI
- Payback periods are often 12–36 months, depending on usage volume.
- Significant cost reductions over the system lifecycle (10–15 years).
3. Predictable Operating Costs
- Electricity costs are stable compared to fluctuating gas pricing.
- Reduced exposure to supplier price increases.
Security of Supply: Clinical Continuity Assured
Key Risks with Traditional Supply
- Delivery delays or shortages
- Supply chain disruptions
- Emergency demand spikes
Benefits of On-Site Generation
- Continuous production of oxygen on demand
- Reduced dependence on external suppliers
- Backup storage integration for redundancy
This is particularly critical for:
- Overnight emergency cases
- Long surgical procedures
- High patient volumes
Regional & Remote Clinics: A Critical Use Case
For practices outside metropolitan areas, oxygen supply challenges are amplified:
Common Issues
- Long delivery lead times
- Limited supplier availability
- Higher transport costs
- Vulnerability during weather events or disruptions
Why Oxygen Generation is Essential
- Enables self-sufficiency
- Eliminates reliance on unreliable delivery schedules
- Improves resilience in emergencies
For remote clinics, on-site generation is often not just beneficial—it is essential infrastructure.
Operational Advantages
1. Workflow Efficiency
- No cylinder handling or changeovers
- Reduced staff time spent managing inventory
2. Space Optimisation
- Eliminates bulky cylinder storage
- Improves safety by reducing high-pressure storage
3. Safety Improvements
- Lower risk of handling injuries
- Reduced hazards associated with high-pressure cylinders
4. Scalability
- Systems can be sized and expanded as the clinic grows

FAQ: Oxygen Generation in Veterinary Clinics
What is on-site oxygen generation for veterinary clinics?
On-site oxygen generation is a system that produces medical-grade oxygen directly within a veterinary clinic using Pressure Swing Adsorption (PSA) technology. Instead of relying on delivered cylinders, clinics generate oxygen on demand from ambient air, providing a continuous and reliable oxygen supply.
How does a PSA oxygen generator work?
A PSA oxygen generator compresses ambient air and passes it through specialised molecular sieves that remove nitrogen. This process produces oxygen with a typical purity of 90-95%, making it suitable for veterinary applications including anaesthesia, critical care, surgery, and oxygen therapy.
Is generated oxygen safe for veterinary patients?
Yes. Oxygen produced by modern PSA systems meets the purity requirements for most veterinary medical applications. These systems are widely used in healthcare and veterinary settings worldwide and provide a dependable source of oxygen for patient care.
What are the benefits of oxygen generation compared to cylinders?
On-site oxygen generation can:
- Reduce oxygen supply costs
- Eliminate cylinder rental and refill expenses
- Improve supply reliability
- Remove delivery dependence
- Increase workplace safety
- Reduce staff time handling cylinders
- Provide oxygen on demand 24/7
How much can veterinary clinics save with oxygen generation?
Savings vary depending on oxygen consumption and location, but many veterinary clinics achieve payback on their investment within 12 to 36 months through reduced cylinder rental, delivery fees, and refill costs.
Why is oxygen generation important for regional and remote veterinary clinics?
Regional and remote clinics often face longer delivery lead times, higher transport costs, and greater exposure to supply disruptions. On-site oxygen generation creates greater self-sufficiency and ensures critical oxygen remains available during emergencies, extreme weather events, or supply chain disruptions.
Can oxygen generation systems support emergency and critical care cases?
Yes. Oxygen generators are designed to provide continuous oxygen production and can be integrated with backup storage systems to support emergency cases, critical care patients, overnight monitoring, and extended surgical procedures.
