Alejandro Jauregui

I am one of the lead RST at El paso sleep center lab, I have been with the company for the past 7 years. As a sleep technician, I am in charge of the patients that come in at night to receive a sleep study. This requires attaching electrodes and sensors to patients to observe their breathing irregularities, sleep patterns and movements during sleep to ensure every detail is documented with precision. This helps us determine if the patient has sleep disorders and how we can treat it. I love what I do, It gives me satisfaction knowing that I help patients get a step closer to receiving a better night’s sleep.
