Jane comes to the ER with breathing difficulties, she tells the doctor that she had a minor car accident, after which she was briefly hospitalized and released to home treatment the next day. Her cervical spine is fixed with a soft collar. The next day she started having trouble breathing, which is getting worse. The doctor listens to her heart and breathing with a stethoscope and tells her that further tests are needed. Jane lies down on the bed and the doctor listens to her again with a stethoscope and then gives her oxygen, first using an oxygen nasal cannula. The doctor puts a probe on her finger to measure oxygen saturation and then measures her BP on her other arm. During the pressure measurement, Jane coughs again and her saturation is still low. You can see her real and fluctuating saturation and pulse values on the monitor. The doctor replaces the oxygen nasal cannula with an oxygen mask with a reservoir to help Jane breathe better, and listens to her again with a stethoscope. Then he sits her down and helps her partially remove her clothes and listens to her again with a stethoscope. Her saturation is still low, the doctor inserts a Guedel airway into her mouth and also provides an intravenous line for administering medication. The doctor then puts a BP cuff on her other arm and connects it to a 5-lead ECG. The video is edited from several camera angles, the soundtrack is edited from the original audio, which unfortunately also includes background music.
