Sci-ed 3D - Respiratory Card
Need to convert litres of oxygen to oxygen percent (FiO2)? Well this reference card does it for you.
Line up the litres per minute with the oxygen device and this grid will give you an approximate FiO2. We know that atmospheric oxygen at sea level is 21% FiO2. So, one important measure of respiratory status is to know what oxygen percent you’re delivering with nasal prongs, Hudson mask, or non-rebreather mask. On the flip side of the card are the names/examples of important types of patient positioning.
