ATI CH.53 Airway Management (Oxygenation)

What is a nursing priority with oxygenation?
-maintaining a patent airway
What is a pulse oximeter?
-a device with a sensor probe that attaches securely to the fingertip, toe, bridge of nose, earlobe, or forehead with a clip or band
Oxygen is a what kind of gas that account for what percent of atmospheric air?
-odorless and tasteless
-21%
Oxygen flow rates vary to maintain an SpO2 of __ to __ using the lowest amount of oxygen to achieve the goal without risking complications
-95% to 100%
The fraction of inspired oxygen (FiO2) is?
-the percentage of oxygen the client receives
Noninvasive measurement of the oxygen saturation of the blood for monitoring respiratory stats when assessment findings include any of the following:
-increased work of breathing
-wheezing
-coughing
-cyanosis
-changes in respiratory rate or rhythm
-adventitious breath sounds
-restlessness, irritability, confusion
Pulse oximetry readings below 90% reflect?
-hypoxemia
Additional reasons for low pulse oximetry readings include
-hypothermia
-poor peripheral blood flow
-too much light (sun, infrared lamps)
-low hemoglobin levels
-movement
-edema
-nail polish
Interventions for readings below 90% (indicating hypoxemia)
-confirm probe placement
-confirm that the oxygen delivery system is functioning and that the client is receiving the prescribed oxygen levels
-place the client in semi-fowler’s or fowler’s position promote chest expansion and to maximize ventilation
-encourage deep breathing
-remain with the client and provide emotional support to decrease anxiety
Administering and adjusting oxygen requires
-a provider’s prescription
Clinical manifestations of early hypoxemia include
-tachypnea
-tachycardia
-restlessness, anxiety
-pale skin, mucous membranes
-elevated blood pressure
-use of accessory muscles, nasal flaring, tracheal tugging, adventitious lung sounds
Clinical manifestations of late hypoxemia include
-confusion, stupor
-cyanotic skin, mucous membranes
-bradypnea
-bradycardia
-hypotension
-cardiac dysrhythmias
High concentrations of oxygen (typically above 50%), long durations of oxygen therapy (typically more than 24 to 48 hr) and the severity of lung disease may result from?
-oxygen toxicity
Oxygen toxicity manifestations include
-nonproductive cough
-substernal pain
-nasal stuffiness
-nausea
-vomiting
-fatigue
-headache
-sore throat
-hypoventilation
