OVERVIEW
Supplemental O2 is provided to patients with adequate spontaneous respirations (ventilation) but inadequate oxygenation. The need for supplemental O2 may be determined by clinical assessment of the patient, pulse oximetry, and arterial blood gas analysis or venous blood analysis when indicated. Supplemental O2 is defined as delivery of O2 in a concentration greater than room air (21% O2) or a fraction of inspired O2 (FIO2) of 0.21.
The provision of supplemental O2 should be treated with the same respect and caution as when administering any drug. Oxygen delivery has safe dosing ranges and may produce effects; toxic effects are possible, especially with delivery of high concentration or with prolonged use.
PATIENT AND FAMILY EDUCATION
- Tell the patient and family members not to smoke while supplemental O2 is in use.
- Explain that the mask should be removed only to eat, blow the nose, expectorate, or vomit, then replaced immediately; the make may be replaced with a nasal cannula for eating.
- Explain the proper position of the mask and the importance of s snug fit. Explain that both prongs of the cannula must be in the nose.
-Encourage questions and answer them as they arise.
