68c Ph2 Exam 5

Oxygen Therapy

QuestionAnswer
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
