Overnight Oximetry Studies

Sometimes a physician may order an overnight oximetry study to see if oxygen is needed for a patient while he or she sleeps.  This study requires two trips to Lodi Health’s Outpatient Services area. 

The first trip will be once an appointment is made.  Lodi Health staff will teach patients how to use a pulse oximeter and send them home with the equipment and instructions in a bag.  That night, patients wear the pulse oximeter while they sleep. 

The second trip will be to return the pulse oximeter.  You can drop it off at the same place you checked in the day before.  Once you return the pulse oximeter, Lodi Health staff download the study and have a physician read the study to determine if the patient needs oxygen while sleeping.
