A blood oxygen saturation of 94% on a cardiac blood pressure monitor is not normal. Oxygen saturation reflects the ability of hemoglobin to carry oxygen in the body, and the oxygen saturation displayed on the cardiovascular blood pressure monitor usually refers to the oxygen saturation of arterial blood, whose normal value is between 95% and 100%. Oxygen saturation is only 94%, indicating that the oxygen-carrying capacity of hemoglobin has decreased, and hypoxia exists. Oxygen needs to be administered in a timely manner, and the concentration and flow rate of oxygen should be adjusted so that the oxygen saturation will slowly return to normal after regular administration of oxygen. Cardiovascular blood pressure monitor can measure some dynamic physiological indicators, if there is a blood oxygen saturation of 94% of the situation, must be timely treatment, and further examination of whether there is anemia and other primary diseases, to prevent the continued aggravation of the condition.
