Final answer:
Aerosol masks generally deliver an FiO2 of 35% to 65%, face tents deliver 30% to 50%, and trach collars can provide 40% to 100% FiO2, with various flow rates depending on the device and patient needs.
Step-by-step explanation:
The aerosol mask, face tent, and trach collar are devices used to deliver oxygen therapy to patients who need more oxygen than is present in the room air. These devices are capable of providing variable amounts of oxygen, often referred to as the fraction of inspired oxygen (FiO2).
It's important to note that the actual amount of oxygen delivered can vary based on factors such as the patient's breathing pattern and the specific device used.
