Individuals with sleep apnea experience low oxygen levels either due to obesity or some clamming up in the neck area. When the brain detects this reduced oxygen flow, it sends reflex signals to the heart, leading to an increased blood flow, blood pressure, and heart rate. This heightens the risk of a cardiovascular event. Once sleep apnea is diagnosed, we can observe a decrease in oxygen saturation levels during a sleep study. When oxygen levels drop significantly, we can use a CPAP machine. This device acts as a valve, preventing the airways from collapsing and ensuring a continuous flow of oxygen. As a result, patients experience improved sleep without having to wake up and cough frequently, and a drastic reduction in their risk of developing high blood pressure and an elevated heart rate, both of which are indirect indicators of increased cardiovascular risk. CPAP offers an excellent solution for patients who are obese and have a thick jugular because inadequate sleep can lead to consistently high blood pressure. Patients may find themselves switching between various medications, even up to four a day, in an attempt to control their blood pressure.
