Nurses use several methods to monitor respiratory status: - Pulse Oximetry: This non-invasive tool measures oxygen saturation in the blood and helps assess the effectiveness of breathing interventions. - Auscultation: Listening to lung sounds with a stethoscope can reveal abnormalities like wheezing, crackles, or diminished breath sounds. - Respiratory Rate and Effort: Observing the rate, rhythm, and effort of breathing can provide critical information about a patient's respiratory status.
