Suitable symptom:
It could do local physical temperature decreasing for high fever or brain disease with body (included pulse, temperature and blood oxygen) check.

Suitable Departments:
Paediatrics department, Newborn department, Emergency departments and any clinics with high fever patient.

Contraindication:
Raynaud's disease, thromboangiitis obliterans, hypertension, coronary artery disease, atherosclerosis, renal, bladder diseases. Cold allergy, excessive sensitivity to cold, cold induced hemoglobinuria.

SpO2 blood volume parameter measure principle:

Blood Oxygen saturation measured by pulse oximetry , which is a continuous, noninvasive determination method of hemoglobin oxygenation saturation .

It determines light quantity from sensor light source through the tissue of the patient (e.g. fingers or ears ), to another receiver. The pierced light quantity depends on many factors, most of which are constant. However, one of these factors is the artery.

Blood flow changes with time, because it is ripple. It is possible to get arterial blood oxygen saturation by measuring absorbed light during pulse. The pulse detection can give a" blood volume" waveform and pulse rate signal.
