Medical air USP

Medical air USP is a critical respiratory adjunct essential for patient therapy at most healthcare facilities.

or more information

We offer commercially produced Medical air USP and specialize in providing safe, reliable, and cost-effective on-site production systems designed to ensure therapeutic quality.

Medical 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.

In order to ensure superior quality, we produce our own high-grade Medical air USP from 21% Oxygen USP and 79% Nitrogen NF.

Quality control

Quality control is essential to ensuring patient safety. At most facilities, you will find it 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.

Most Medical air USP dispensed through a facility's central pipeline system is made on-site with compressor systems.

To help ensure your patients are administered precise Medical air USP, we developed aerALin™ — our parametric batch release quality control system. It validates your Medical air USP to meet good manufacturing practices and reflect the production quality control experience from our plants.
