COURSE SUMMARY
Arterial blood gas interpretation is a critical nursing skill that supports rapid recognition of respiratory compromise, metabolic imbalance, and clinical deterioration. Yet many nurses report uncertainty when interpreting ABG results, especially in fast-paced care environments where timely decisions matter. This practical continuing education course provides a simple, step-by-step framework designed specifically for nursing practice. Learners will gain confidence in understanding ABG values, recognizing acid-base disturbances, identifying red-flag findings, and applying interpretation skills to realistic patient care scenarios.
COURSE DESCRIPTION
Arterial blood gas analysis remains one of the most valuable diagnostic tools in acute and critical nursing practice. ABG interpretation provides insight into oxygenation, ventilation, acid-base balance, and evolving physiologic instability that may not yet be obvious through physical assessment alone. For nurses practicing in medical-surgical units, telemetry, emergency departments, critical care, perioperative care, long-term care, and home health environments, understanding ABG findings can improve escalation decisions, communication with providers, and patient outcomes.¹
Despite its importance, ABG interpretation is often perceived as intimidating or overly complex. Many nurses remember formulas, memorized charts, or fragmented classroom instruction that did not translate easily into real bedside application. This course takes a practical nursing-focused approach that simplifies ABG interpretation into a structured clinical process. Learners will develop the ability to recognize common acid-base disturbances, identify compensation patterns, evaluate oxygenation concerns, and apply findings to realistic patient care scenarios. By the end of this course, participants will have a practical framework that improves confidence, communication, and clinical decision-making.²
