Extremely low saturation blue-gray medical environment, cold and blue hues dominate the ward. Heart monitor central light source structure, unstable green/white waveform flickers strongly, forming overall tension in the space.

Medicycera is performing CPR compressions from the side of the patient's chest, arms straight, leaning forward with body weight for vertical compression, hands precisely fixed on the center of the chest, repeating strong compression rhythm. Face is in a state of extreme tension, jaw and mouth area are stiff, and forehead is tense, gaze fixed on the patient's chest. Qusera, a Korean woman nurse in her 20s, full-body. Ash pale pink hair, short twin tails, voluminous curls naturally swaying with the CPR wind and movement. Small nurse cap, Red Cross. Rose pink+white corset. Rose pink tiered skirt.

The overall environment is dominated by a single heart monitor in an extremely low saturation ICU, maintaining a tense emergency situation.
