“Sufficient oxygenation is vital to maintain life. When prioritizing nursing interventions, we often refer to using the “ABCs,” an acronym used to signify the importance of maintaining a client’s airway, breathing, and circulation. Several body systems work collaboratively during the oxygenation process to take in oxygen from the air, carry it through the bloodstream, and adequately oxygenate tissues. It is important that all parts of the system work together to ensure that oxygen is delivered appropriately to tissues within each system. Any alteration in these systems can have catastrophic implications on a client’s health.”
