On-site medical air quality control

Parametric batch release quality control system.

or more information

aerALin™ is our exclusive parametric batch release quality control system - the first of its kind in Canada. It is designed to provide thorough quality control for on-site production of medical gases, including Medical air USP, Oxygen USP, or Nitrogen NF.

With aerALin™, you are ensuring your facility introduces into its medical gas pipeline only quality controlled medical air identified by batch numbers, and tested within the scope of the United States Pharmacopeia (USP). It validates your Medical air USP to meet good manufacturing practices and reflect the production quality control experience from our medical cylinder fill plants.

When made on site, the National Building Code of Canada mandates CAN/CSA Z7396.1: “The owner of the healthcare facility shall ensure that the product delivered by a compressor system used as a source of medical air meets the specifications for Air USP” 

With aerALin's precise quality control systems, hospitals can validate the medical air in their medical gas piping systems and regulate against breaches in:

  • Humidity
  • Oxygen content by volume
  • Nitrogen dioxide ppm
  • Nitric oxide ppm
  • Carbon dioxide ppm
  • Carbon monoxide ppm
  • Sulphur dioxide ppm

aerALin's quality control service includes:

  • A sensor array to validate against critical Medical air USP specifications
  • Actuated valves to prevent off-spec product entering the pipeline
  • Continuous traceability through recording of monitored parameters
  • Quality compliance reporting
  • Remote monitoring and alarm notification
  • Optional CO2 mitigation through our Patient Protect Purge Control (P3C)
  • Remote access and management through Smartphone, Tablet and PC
  • Flow monitoring and totalization
  • VOC (Volatile Organic Compounds) filtration

Key features

  • Promotes patient welfare through safe & regulated medical air

  • Recognize breaches in medical air quality through continuous monitoring

  • Available for purchase, rent-to-own, or on a monthly facility fee basis

  • Made in Canada and supported by our national service network

Prioritizing patient safety

At most facilities, you will find that Medical air USP is made on-site for economic reasons. The quality of Medical air produced is directly linked to the quality of the raw material, outdoor air.

Medical air USP is treated as a drug, and whether you supply it from an on-site source or from factory validated reserve high-pressure cylinders, your patients' welfare depends on its quality.

Maintaining Medical air USP compliance and economizing purge air loss

P3C provides a dual setting purge control, with dryer purge activation based on achieving either a specific moisture or carbon dioxide trigger level. The result is guaranteed medical air USP acceptable levels for moisture and carbon dioxide and optimal purge economization.

Medical air USP applications

Medical air USP is a critical respiratory adjunct to numerous respiratory therapies. Medical applications include:

  • Mechanical ventilation: Medical air may be used as a carrier gas to supply respirators in respiratory assistance in anaesthesia, resuscitation, ventilation and isolette environmental control.
  • Nebulisation: In aerosol treatments, medical air may be used as a gas vector for the inhaled drugs when oxygen supplementation is not required.
  • Hyperbaric chambers: For this therapy, patients enter chamber to breathe in pure oxygen for a short period in air pressure levels 1.5 to 3 times higher than average. The goal is to fill the blood with enough oxygen to repair tissues and restore normal body function.

Patients such as neonates and people suffering from acute respiratory distress syndrome have delicate respiratory systems sensitive to oxygen toxicity. They often require a precise and reliable concentration of Medical air USP to control their oxygen exposure and breathe properly.
