ABG Acid-Base eval 1.7

ABG Acid-Base evaluation guides clinicians through a systematic approach to analyzing arterial blood gases and electrolytes in order to identify acid-base disorders and formulate diagnostic hypotheses for unwell patients. The methodology is primarily based on a worksheet developed by Dr. Erik Rupard derived from medical literature. This resource not only provides solutions but equally emphasizes the importance of stepwise analytical thinking and fundamental concepts being learned during the process. Users, whether clinicians or learners, will acquire valuable insights that enhance patient care and are likely to enhance their own knowledge and independence for future occurrences. It serves as a valuable tool for clinicians who occasionally conduct these tests and may not have every detail memorized. The differential diagnoses encompass well-known mnemonics such as MUDPILERS, CHAMPS, CLEVER PD, and HARDUPS, supported by detailed explanations and examples.

The application addresses various common inquiries including the causes of metabolic acidosis and respiratory alkalosis, methods to calculate predicted pCO2 and corrected bicarbonate, identification of the primary acid-base disorder, and the presence of any additional acid-base imbalances along with their identification.

This application is tailored for practicing clinicians such as internists, family physicians, emergency room physicians, cardiologists, pulmonologists, intensivists, hospitalists, resident physician trainees, medical students, nurse practitioners, physician assistants, and other fellow clinicians alike. As both an educator and clinician, feedback is welcomed with appreciation in efforts to enhance this tool.

Key Considerations:

1. Several thresholds and cut-offs are subjective and subject to debate; hence interpreting the presence and severity of disorders suggested by the application requires sound judgment.
2. The application aids in data evaluation. In case an error occurs, the tool does not oppose you but eventually offers a comparison of your findings against the disorders identified using the same algorithm.
3. Patients transcend their numerical values and data; each one is unique. Utilize this information as a foundational assessment for your patient while encouraging critical thinking throughout your evaluation process.
