What does the medical order "sos" mean?

　　The medical order "sos" stands for "siopussit," meaning to administer the medication once if necessary. The detailed explanation is as follows:

　　Siopussit is a type of temporary medication order, used for diagnostic tests or temporary treatments such as surgery or X-ray imaging. It is valid within 12 hours, during which it can be administered only once. If the patient does not receive the medication within the 12-hour period, "not used" should be recorded on the medical order sheet, and the order then becomes invalid. If the patient receives the medication within 12 hours, the administration time must be documented on the order sheet to indicate that the medication has been given. If the patient requires medication more than 12 hours later, the physician must issue a new medical order.

　　Under normal circumstances, a temporary medical order only becomes effective after being signed by a physician. During this period, any issues should be promptly communicated with the doctor. Patients are required to actively cooperate with their treatment and strictly follow medical instructions. They must not arbitrarily increase or decrease dosages to avoid causing serious harm to their health.
