SAIPAN — The Commonwealth Healthcare Corporation says its medical oxygen supply remains unaffected by disruptions reported in Guam, reassuring the public that patient care at its facilities is not at risk.
CHCC said it does not rely on liquid oxygen systems, which are at the center of the supply concerns affecting Guam. Instead, the hospital operates an on-site oxygen generator using Pressure Swing Adsorption technology, which produces high-purity oxygen directly from ambient air. The system was replaced in 2020 and continues to function normally. CHCC’s oxygen cylinder refilling station is also fully operational.
“Our Oxygen Generator System was replaced in 2020 and is an advanced, industrial or medical-grade machine designed to produce high-purity oxygen directly from ambient air,” said Jesse M. Tudela, chief operating officer of Ancillary and Support Services. “It offers a cost-effective, safe, and continuous alternative to purchasing, storing, and replacing traditional compressed oxygen cylinders.”
Tudela said the PSA system typically produces oxygen at 90 to 95 percent purity or higher. Routine maintenance includes checking air filters and periodically replacing zeolite sieve material, which has a long lifespan under normal operation.
CEO Esther L. Muña said there is no impact to oxygen availability at CHCC facilities.
“We remain committed to ensuring uninterrupted, high-quality care for our community,” Muña said.
