68c Ph2 Exam 5
Oxygen Therapy
| Question | Answer |
|---|---|
| Hypoxemia | Decrease of O2 in the blood (arteries) |
| Cyanosis | Bluish color to tips, fingers, and toes from low O2 in blood' increase of CO2. |
| Nasal Cannula benefits | appropriate for all PT; PT can talk, eat, and don't feel they are sufficating |
| Pros and cons of Mask | pros: Can start a 6L Cons: PT can't talk, feel they are sufficating, |
| Non-rebreather | 80-100%; fills up when inhale; never fully collapses on exhale; MOST EFFECTIVE |
| SS Hypoxemia | decreased LOC, anxiety, apprehension, fatigue, vertigo, Tachycardi and bradycardia if not corrected, respirations increase if not corrected shallow and slowed, B/P elevated then decreased if not corrected, cardiac dysrhythmias, pallor, cyanosis, clubbing |
| pallor | reduction in O2 in skin caused by illness or emotional shock; loss of color; decrease in melanocytes in skin |
| External respiration | change between lungs and air we breathe |
| internal respiration | cellular exchange between cells |
| clubbing | most commonly in heart or lung disorder; fingernails become round and swollen from decreased O2 |
| cyanosis S/S | Pallor; dark skinned individuals may have a grayish color; do to excessive concentration of CO2 in blood |
| Precautions in Oxygen therapy | Fire, smoking, electrical equipment, drying of tissue, oxygen toxicity, wool blankets, secure portable O2 cylinder; oral hygiene every 3-4 hours; cotten balls around ears if NC |
| Oxygen does not burn, but it... | supports combustion; "feeds the fire" |
| Nasal cannula | 4-6Liters; USUALLY 2L; semi-fowler's position; put in water and blow out at 6L/min to ensure patent; higher rate reduces respiratory rate; easily dislodged |
| Mask | 24-55% @ 3-7 Liters; |
| Simple mask | low to med concentrations > 5L per min |
| Partial Rebreather | 60-80% concentrations; when you inhale it fills up and collapses when exhales |
| COPD Patient | Body is used to lower levels of O2 and higher level CO2 so giving too much can knock out hypoxia drive |
| normal level of O2 | 85-100% |
| PT over 80 normal level O2 | possibly 75%+ |
| Venturi | Consistent FiO2 (fraction of inspired O2) delivered; different colored tubing |
| face tent | mostly for pediatric patients |
| goal for O2 Admin | improve or maintain systemic oxygenation |
| Patient education | Reason for treatment, safety issues, activity restrictions, stop smoking, home care |
| is oxygen considered medication | YES; but if PT is totally deSat, do it |
| as we give O2... | Patient symptoms should reverse |
| Complications | dryness of mucus membranes, if skin cracks it gives way for infection |
