A nurse administering oxygen therapy to a patient in a hospital bed
This photograph shows "The new oxygen-therapy apparatus in use.” at an unknown hospital. Manufacturers of medical equipment began to mass-produce respiratory therapy equipment in the 1920s. By the 1930s the beneficial uses of oxygen therapy were recognised, with oxygen piping systems being constructed for hospital rooms. Later in the decade continuous oxygen therapy had begun to be recognised as more beneficial than administering oxygen to patients intermittently, but there was still some reluctance amongst the medical profession.
