Final answer:
The oxygen concentration in standard transport ventilators can vary, with some capable of delivering from 21% (room air) to 100%. Monitoring oxygen delivery is crucial to prevent oxygen toxicity, using tools like pulse oximeters to measure blood oxygen percent saturation.
Step-by-step explanation:
For standard transport ventilators, the oxygen concentration is usually fixed at a specific percentage. This percentage is often set to deliver a certain fraction of inspired oxygen (FiO2) to the individual using the device, however, the fixed percentage can vary depending on the model of the ventilator and specific clinical settings. Most transport ventilators are capable of delivering FiO2 ranging from 21% (equivalent to room air) up to 100%. In emergency or standard pre-set hospital ventilators, oxygen concentrations can be often fixed at 100% unless titrated to a lower percentage based on the patient's oxygenation status and clinical goals.
It's important to note that while oxygen is essential for life, too much oxygen can also be harmful, leading to oxygen toxicity, especially at high concentrations over a long period. Thus, the administration of oxygen via ventilators must be carefully managed and monitored using devices such as pulse oximeters, which measure percent saturation of oxygen in the blood, with normal readings ranging from 95-100 percent.
