One common symptom of<unk>  is cyanosis, a bluish discoloration of the skin resulting from an inadequate amount of oxygen in the blood. If<unk>  remains without any treatment, cardiac arrest will occur within minutes of hypoxemia, hypercapnia or both. At this point, patients will be unconscious or about to become unconscious. Symptoms of<unk>  compromise can differ with each patient. Complications from<unk>  compromise are increasing rapidly across the clinical spectrum, partly due to expanded use of opioids combined with the lack of standardized guidelines among medical specialties. While<unk>  compromise creates problems that are often serious and potentially life-threatening, they may be prevented with the proper tools and approach. Appropriate patient monitoring and therapeutic strategies are necessary for early recognition, intervention and treatment.
