During emergency medical care, oxygen masks are used to deliver oxygen efficiently to patients. These masks are available in a range of sizes suitable for adults, pediatric patients, and even infants. Non-rebreather O2 Masks, featuring a one-way valve and an oxygen reservoir bag to reduce ambient air entrapment, are among the most popular styles. High and Medium Concentration Masks are also available for patients requiring greater amounts of oxygen. QuadMed provides a comprehensive selection of Oxygen Masks for both adults and pediatrics from renowned brands like Teleflex, Smiths or Salter Labs.
