Oxygen Therapy Flashcards
Nasal cannula
Rate: 1-6 liters per minute
Concentration: 24-45%
Breathing, COPD patients with low O2 concentration
Pocket mask without oxygen
Manual CPR use
Concentration: 16% (mouth) or 21% (room oxygen)
Breathing, non-breathing
Trauma victims
Pocket mask with oxygen
6-8 L/min
44-55%
Breathing, non-breathing
Trauma victims
Simple face mask
6-10 L/min
40-60%
Breathing, mild or moderate respiratory distress
Venturi mask
4-15 L/min
24-40%
Also controls humidity
Breathing, COPD, asthma, stable patient
Bag valve mask resuscitator without oxygen
Manual/CPR
Room oxygen 21%
Breathing, non-breathing (best)
Apnea
Bag valve mask resuscitator with oxygen
10-15 L/min
90-100%
Manually with oxygen for apnea or inadequate ventilation
Partial rebreathing mask
8-15 L/min
60-80%
Breathing, non-breathing
Non-breathing mask
10-15 L/min
90-100%
COPD, carbon monoxide poisoning, smoke inhalation, or any patient who require high flow oxygen and do not need breathing assistance
Retrolental fibroplasia
Oxygen therapy in premature infants can lead to irreversible blindness
Absorption atelectasis
High alveolar oxygen concentration can cause alveolar collapse. The increased oxygen causes the alveoli to collapse due to the replacement of nitrogen leading to abnormal surface tension
Oxygen toxicity at __% for extended periods __. Symptoms include. What to do?
More than 60%
3-24 hours
Chest pain, cough, SOB
Monitor patient and lower oxygen concentration if they complain
Caution with oxygen therapy
Patients with COPD since they have high PCO2 which causes them to lose primary drive for breathing.
If placed on high flow oxygen they will not be able to ventilate leading to increase PCO2 and RESPIRATORY FAILURE!!!!!
Goal of oxygen therapy
SaO2 greater than 90%
Cyanosis detected at
Less than 85%
Frank cyanosis at 67%
