A home sleep test (HST) is a sleep test to assess for sleep apnea. You can do it in the comforts of your home at your convenient sleep time schedule. The test measures your respiratory airflow (breathing), respiratory effort, body position, pulse rate, oxygen, snoring. Some of the recent HST equipments have sleep monitoring as well. 

 

HST can be done on one night or two nights to assess any night to night variability.
