pulse oximetry
This noninvasive measurement expresses the percentage to which hemoglobin is filled with oxygen, with a normal value typically being greater than 95%
peripheral oxygen saturation (SpO2)?
This simple and comfortable device is adequate for short- or long-term use and allows the patient to breathe through the mouth or nose.
nasal cannula?
To prevent fire hazards, oxygen delivery systems should be kept at least this many feet away from any heat source or open flame.
5 to 10 feet?
This must be added to a low-flow oxygen system whenever the flow rate is ordered at 4 L/min or higher to prevent drying of the mucosa.
humidification?
This is the specific type of rigid, minimally flexible plastic catheter used to remove thick pharyngeal secretions from the mouth
To ensure accurate readings, a nurse should remove these two items from a patient's finger before applying a pulse oximetry sensor
nail polish and artificial nails?
This cone-shaped high-flow device uses various sized entrainment ports to deliver a precise concentration of oxygen
Venturi mask?
patient transport?
1 to 6 L/min?
This is the frequency at which a pulse oximeter sensor should be relocated, or more often if skin integrity or tissue perfusion is compromised
at least every 4 hours?
When using a mask with a reservoir bag, the nurse must ensure the bag remains in this state to prevent the patient from rebreathing carbon dioxide
fully (or partially) inflated?
While applying a nasal cannula or mask can be delegated to nursing assistive personnel (NAP), this specific skill related to oxygen administration must be performed by a nurse.
initiating or adjusting oxygen flow rates?
60% to 90%?
To avoid stimulating the gag reflex or causing vomiting, a rigid suction device should never be reached beyond this area
oropharynx (into the laryngopharynx)?
ear or the forehead?
This shield-like device is used primarily for humidification or for patients who cannot tolerate a tight-fitting mask.
face tent
These four symptoms—confusion, headache, decreased LOC, and somnolence—are signs of this oxygen-related complication
oxygen toxicity (or carbon dioxide retention)?
High-flow nasal oxygen therapy can provide warmed, humidified oxygen at rates up to this many liters per minute.
50 L/min?
This is the recommended position for a recovered patient with a decreased level of consciousness to encourage drainage after suctioning
left lateral recumbent?
These three specific factors can interfere with accurate SpO2 readings because they affect how much light is reflected from or absorbed by hemoglobin.
carbon monoxide, jaundice, or intravascular dyes?
For a patient with chronic obstructive pulmonary disease (COPD), the nurse should aim for this specific target SpO2 range.
88% to 92%
To ensure safety, oxygen and IV lines should be routed in this direction, while enteric lines are routed toward the feet
toward the head?
This occurs when high oxygen concentrations "wash out" nitrogen from the alveoli, potentially causing them to collapse.
absorption atelectasis?
In addition to replacing the device if it's soiled with blood or vomitus, the rigid suction tip and tubing must be changed at this minimum interval
every 24 hours?
