Final answer:
Safe oxygen rates for a patient without a medical order are often between 1-2 liters per minute, although oxygen therapy should be guided by a healthcare provider to prevent complications like oxygen toxicity or respiratory suppression.
Step-by-step explanation:
The question asks for the safe oxygen (O2) rate for a patient without a specific medical order. Generally, without a healthcare provider's prescription, oxygen should be started at a conservative flow rate, which is often 1-2 liters per minute. However, it is critical to note that oxygen therapy without a physician's guidance can be dangerous as oxygen delivery needs can differ greatly among patients. Each individual may require different levels of supplemental oxygen due to a variety of factors including their overall health, level of distress, and specific medical conditions.
Therefore, it is essential for a patient's oxygen levels to be closely monitored, and any supplemental oxygen should ideally be administered under the guidance and prescription of a medical professional. Notably, administering too much oxygen can also result in deleterious effects, such as oxygen toxicity or suppression of a patient's drive to breathe.\
