Final answer:
A pulse oximetry level of SaO₂ at 82% in a patient with acute asthma indicates hypoxemia, a lower-than-normal blood oxygen level, which is critical and may require immediate medical intervention.
Step-by-step explanation:
When a patient is admitted with acute asthma and shows a pulse oximetry level of SaO₂ of 82%, this indicates hypoxemia, which is a lower-than-normal level of oxygen in the blood. The normal range for pulse oximeter readings is between 95-100 percent, and readings below this suggest that there is a reduced level of oxygen being carried in the blood to various organs and tissues. This condition may require prompt medical attention to restore adequate oxygen levels in the patient's bloodstream, often through supplemental oxygen and other respiratory support interventions.
