Health care plagued by new supply chain shortages

Details: Some hospitals around the U.S. recently began seeking donations of aluminum crutches, walkers and wheelchairs.

The FDA is investigating allegations that used medical gloves were washed and resold as new gloves.

Blood tubes and Foley catheters are also among some of the products in short supply at the University of Alabama at Birmingham, ABC 33/40 reported.

There are shortages of raw materials for manufacturing, including semiconductors, or chips commonly used in electronics, and plastic resins that can be used to make everything from car parts to heart valves.

The chip shortage hit ResMed, a company that creates ventilators, sleep apnea machines, and other respiratory equipment, San Diego Union-Tribune reported last week.
