-1-6 liters(24-44% total oxygen)for adult
- can eat and talk
- dries mucous membranes ( can humidify)
Nasal Cannula: FiO2 24-44% at 1-6 L/min; client is able to eat, talk and ambulate, watch for skin breakdown and dry mucous membranes and easy dislodging; use water soluble gel to prevent dry nares and provide humidification for flow rates above 4 L/min |

Term

Definition
- good for mouth breathers
- 4-10 liters ( 35-50% oxygen)
- "suffocating"
Covers the clients nose and mouth
FiO2 of 40-60%; 5-8 L/min
Easy to apply, more comfortable than nasalC, simple delivery
-5 L/min or lower may cause Co2 rebreathing
-Poorly tolerated with claustrophobia/anxiety
-Caution with high risk aspiration or airway obstruction
-Secure fit and wear NC during meals |
|

Term
|
Definition
- 4-10 liters (24-50% oxygen)
- exact amount of O2 delivery
- not as drying to mucous membranes
- can't eat, talk
FiO2 of 24-55% at 2-10 L/min via different size adaptors
Delivers most precise oxygen concentration
-No humidification required
-best for clients with chronic lung disease
-expensive
-assess flow rate frequently and make sure tubing is free of kinks |

Term
| What does a pulse oximeter measure? |
|
Definition
| Arterial oxygen saturation via a wave of infrared light that measures light absorption by oxygenated and deoxygenated hemoglobin in arterial blood |
|

Term
|
Definition
- 6-10 liters ( 35-60% oxygen)
-Re-breather some of your exhaled volume
- easy to humidify
- bag fills on exhalation
- partial collapse on inhalation
covers nose and mouth
FiO2 of 60-75%, rate 6-11 L/min
-Mask has a reservoir bag with no valve; client rebreathes up to 1/3 exhaled air together with room air
-Complete deflation causes Co2 buildup
-NC during meals; secure fit
-Caution: aspiration or airway obstruction risk patients |
|
|
Term
|
Definition
- 6-15 liters (60-100% oxygen)
- highest possible oxygen concentration without being on ventilator
-drying, confining,and can't eat or talk
-only breathing oxygen.. not en-training form the "outside air"
-bag will not totally deflate on inhalation
FiO2 of 80-95% at 10-15 L/min to keep bag 2/3 full during I and E
Delivers highest O2 concentration possible without intubation
-one way valve allows client to inhale max O2 from bag, two E flaps cover to prevent room air from entering
-Caution: clients with high aspiration/obstruction risk, NC during meals
-Perform hourly assessment of valve and flap |

Definition
Below 91% requires interventions to help client regain acceptable levels (using lowest amount possible)
Below 90% indicates hypoxemia
Below 86% is an emergency
Below 80% is life threatening
Lower the level, the less accurate the value |
|
|
Term
| Order of what to do if SaO2 is below 90% |
|
Definition
This indicates hypoxemia
-Confirm that sensor prove is properly placed
-Confirm that oxygen delivery system is functioning and that client is receiving prescribed levels
-Place client in Semi-Fowlers or Fowlers
-Encourage deep breathing
-Report significant findings
-Remain with client and provide emotional support to decrease anxiety |
|
|
Term
| Early/late signs of hypoxemia |
|
Definition
Early: tachypnea, tachycardia, restlessness, pale skin and mucous membranes. elevated BP, symptoms of respiratory distress
Late: confusion and stupor, cyanotic skin and mucous membranes, bradypnea, bradycardia, hypotension, cardiac dysrhythmias |

Definition
Face tent-fits loosely around the face and neck, and tracheostomy collar-small mask that covers surgical opening of trachea
FiO2 of 24-100% at at least 10L/min
Humidification is provided
-Use with clients who cant tolerate masks well; clients with facial trauma, burns and thick secretions
-Frequent monitoring due to high humidification; ensure adequate water in canister
-Empty condensation
-Make sure tubing does not pull on tracheostomy |
|
|
Term

Definition
.s.: nonproductive cough, substernal pain, nasal stuffiness, n/v, fatigue, headache, sore throat, hypoventilation
-Use lowest level of oxygen to maintain sats
-Monitor ABGs and notify if Sats are outside range
-Use o2 mask with: CPAP-continous positive airway pressure, BiPAP-bilevel positive airway pressure, or PEEP-positive end=expiratory pressure
-Reduce FiO2 as soon as condition permits |

Definition
Rely on low levels of arterial oxygen as their primary drive. It is a chronic condition of hypoxemia and hypercapnia. High levels of oxygen can decrease or eliminate respiratory drive
-Monitor RR and pattern, LOC, and SaO2
-Lowest liter flow; a venturi mask if tolerated for precision
-Notify provider of resp depression (low RR or LOC) |

Post No Smoking, Oxygen in Use signs
-Know where extinguisher is
-Educate about fire hazard of smoking with oxygen
-Have client wear cotton gown; synthetic or wool generate static electricity
-Ensure all electric devices work properly and machinery is grounded
-Do not use volatile, flammable materials near client (alcohol, acetone) |
