Oxygen is a common practice in sick children.
- It is very important to remember that oxygen is now considered as a drug and it needs to be prescribed by a doctor before it is administered
- Like any Drug, excess of this can cause side effects to the patient and hence it needs to be used very judiciously
- Oxygen is always given as FiO2 or the fractional inspiration of oxygen
- Methods of giving oxygen
- The various methods of administration provide different quantities of oxygen (FiO2)
- The choice of oxygen device is made based on the age of the child and the requirement of Fio2.
- In children less than 8 months, the head box or nasal prongs can be comfortable
- In older children you can use the nasal prongs or the masks.
- Most of these techniques supply dry air which can irritate the respiratory system. So for prolonged use beyond a couple hours, you may need to humidify it.
|Method||Maximum FiO2||Ideal Flow rate|
|Nasal prongs||50%||< 1 L to 5 Liter|
|Mask without reservoir||50%||5 to 10L|
|Mask with reservoir||90%||5 to 10L|
|Head box||95%||5 to 10L|
