How does a cpap machine detect apnea? Automatic CPAP machines vary slightly in that they can detect a collapse of the airway by measuring resistance and react by increasing the pressure as needed during the night to further resolve the sleep apnea. These devices will also test lower pressures and adjust downward if possible.
How does CPAP machine detect events? The algorithms for event detection used by these devices are based on measurements of airflow, vibration, and airflow profile flattening. Clinicians use the event detection information recorded by these PAP devices to assess treatment efficacy.
How many apneas per hour is normal? That’s because it’s considered normal for everyone to have up to four apneas an hour. It’s also common if your AHIs vary from night to night. For some CPAP users, even higher AHIs are acceptable, depending on the severity of your sleep apnea.
How does CPAP detect events per hour? When you have an apnea, air stops flowing to your lungs for 10 seconds or longer — that is, you actually stop breathing. A hypopnea is a partial blockage of the airway that lasts for 10 seconds or longer. Your CPAP machine notes the number of breathing events you have in each hour.

Can full blood test detect ovarian cancer?
The CA-125 blood test measures the amount of a protein called CA-125 in the blood. Many women with ovarian cancer have high levels of CA-125. This test can be useful as a tumor marker to help guide treatment in women known to have ovarian cancer, because a high level often goes down if treatment is working.
How to detect mycoplasma?

Can a blood pressure monitor detect a heart attack?
Blood pressure is not an accurate predictor of a heart attack.

Is there a device that can detect a heart attack?
