Respuesta :
The nurse would primarily provide oxygen therapy to the child with less than 70 beats per minute and 95% of oxygen saturation.
For a 3-years old child, normal respiratory rate is more than or equal to 70 beats per minute and oxygen saturation is up to 95%. For a child, undergoing treatment for pneumonia, asthma, or bronchitis, oxygen should be provided under severe conditions.
The two main sources of synthetic oxygen are oxygen cylinders and compatible concentrators. Nasal prongs are the most reliable and safe option to provide oxygen to a child. These are small tubes generally inserted into the nostrils and are non-invasive. They do not block the entry of nasal air unless the nostrils are blocked by any kind of mucus inside.
The nurse should keep a note of the oxygen delivery with the help of a pulse oximeter. She should set the delivery at a rate of 1-2 liters per minute. She should also take care of the nostrils getting blocked by mucus inside and the position of nasal prongs.
