Assessing Oxygenation in Acute Care
June, 21, 2012 10:00 a.m. EST (U.S.) - 7:00 a.m. PST (U.S.) - 14:00 CET (Europe)
Proper assessment of oxygenation is of paramount importance in acute care. To fully understand the patient’s status, healthcare professionals must look beyond calculated estimates of oxygen saturation. Evaluating hemoglobin levels, identifying dyshemoglobins, and measuring arterial blood gases, help to tell a more complete story. Effective treatment demands recognizing the clinical impact of these values, understanding the technologies used to quantify them, and having confidence in the underlying measurement principles.
This webinar provides an overview of the capabilities, limitations and differences in three oxygenation measurement technologies: pulse oximetry, pulse CO-oximetry, and CO-oximetry with arterial blood gases. Through a series of case examples, the hemoglobin-oxygen relationship and the clinical relevance of dyshemoglobins are explored. The importance of pO2, pCO2, pH, bicarbonate, and base deficit blood levels in a patients’ clinical presentation is discussed. Underlying measurement principles for pulse oximetry and CO-oximetry is also included.
At the conclusion of the seminar, attendees should be able to:
- Identify key differences in pulse oximetry, pulse CO-oximetry, and CO-oximetry with arterial blood gases
- Identify a number of hemoglobin abnormalities, their causes, and clinical manifestations
- Define the principles of CO-oximetry measurement
