What is the primary purpose of obtaining pulse oximetry in patients with respiratory issues?

The primary purpose of obtaining pulse oximetry in patients with respiratory issues is to monitor oxygen saturation. This non-invasive method uses light absorption properties of hemoglobin to determine the percentage of hemoglobin that is saturated with oxygen. In patients with respiratory problems, it is vital to assess how well oxygen is being transferred from the lungs into the blood. A low oxygen saturation level could indicate inadequate respiratory function or hypoxemia, which requires prompt intervention.

Pulse oximetry is essential in clinical settings for ongoing assessment of a patient's respiratory status, allowing healthcare providers to make informed decisions regarding supplemental oxygen needs or interventions to improve oxygenation. While other parameters, such as respiratory rate, carbon dioxide levels, and heart rate, are important aspects of patient assessment, pulse oximetry specifically addresses the effectiveness of respiratory function as it pertains to oxygen delivery, emphasizing the importance of oxygen saturation in patient care.
