What is the key treatment in respiratory care?

The key treatment in respiratory care is Oxygen Therapy.

Respiratory Care practitioners utilize this technique to administer Oxygen directly into a patient's breathing passages to improve respiration. Oxygen Therapy supports and improves breathing by maintaining and regulating its levels within the bloodstream by administering a higher fraction of inspired oxygen (FiO2), aiding individuals unable to meet oxygenation and ventilatory needs on their own.
