Zhou Yixian was about to leave and arrange for Zhang Xi's transfer to a general ward when his gaze inadvertently fell upon the monitor.
Zhou Yixian's eyelids twitched. I must have seen that wrong, he thought, taking two more steps forward. In the time it took for those two steps, a yellow alarm blared from the monitor. It sounded once before immediately escalating to red.
The jarring alarm instantly threw the observation ward into a tense state. Doctors and nurses not currently engaged in rescue efforts hurried towards the sound.
Zhou Yixian was startled. How could his blood pressure and oxygen saturation drop so quickly? Reaching Zhang Xi's side, he could hear the patient's shallow, labored breathing.
