Oxygen Therapy Flashcards
What are 5 indications for oxygen therapy
-Documented hypoxemia
-Acute care situation where hypoxemia is suspected
- severe trauma
- acute myocardial infarction
-short term therapy or surgical intervention
Are there any contraindications for o2 therapy
There’s none
What are the 6 precautions/ complications with o2 therapy
- If PaO2 is greater than 60 torr causing ventilatory depression which can occur with evelated PaCo2
- absorption atelectasis, oxygen toxicity, or depression of ciliary and leukocytic function can happen with an Fio2 greater than 0.5
- should be cautious delivering supplemental oxygen to paraquat poisoning patients
- deliver minimal levels of o2 during laser bronchoscopy to avoid intratracheal ignition
- fire hazard
- bacterial contamination
What are the 6 low flow o2 devices
Nasal cannula, simple mask, oxymask, oxymizer, partial rebreather mask, and non rebreather mask
What are the 3 high flow o2 decides
High flow nasal cannula, air entrainment mask, air entrainment nebulizer
What is the Fio2 range for nasal cannula and its special considerations
Egans: 24-40%
Rule of 4: 24-44%
Special considerations:
-Liter flow: 1/4-6 LPM
-Use a bubble humidifier when flow is at. 4 LPm or greater
- O2 concentration depends on patients breathing pattern ( tidal volume and minute ventilation)
What’s the Fio2 range and special considerations on an oxymizer
Up to 6 LPM- Use rule of 4 (24-44%)
Special consideration:
-Never use a bubble humidifier ( condensation)
- cuts o2 in half to conserve o2
- not recommended for long term high flow use
What’s the Fio2 range and special considerations for a simple mask
35-50% / 5-10 LPM
Special considerations:
-Never use bubble humidifier
- short term use only
- never use less than 6 LPM
What is the Fio2 range and special considerations on a partial rebreather mask
40-70% / Flow must be >10 LPM
Special consideration:
- short term only
- reservoir bag shouldn’t collapse
- No bubble humidifier
What’s the Fio2 range and special considerations for a non rebreather mask
60-80% / Minimum flow 10-15 LPM until reservoir bag is flushed ( full)
Special considerations:
- Never remove one way valves
- reservoir bag shouldn’t collapse
-short term
What’s the Fio2 range and special considerations for a oxymask
24-90% / 1-15 LPM
Special considerations:
- use bubble humidifier for flow < 6 LPM
- has widest range of Fio2 and liter flow
- less claustrophobic
What’s the Fio2 range and special considerations for an air entrainment nebulizer
28-100% / 10-15 LPM
Special consideration:
-Never use flow <8 LPM
- muse use sterile water
- can be paired with other masks
Fio2 range and special considerations for air entrainment mask
24-50% or 24-60%
Special consideration:
- Never cover entrainment port
- most accurate when delivering Fio2
- best for Co2 retainers or hypoxia drive patients
Fio2 range and special considerations for high flow nasal cannula
21-100%
Adults: 20-35 LPM
Infants: 4-8 LPM
Special considerations:
-heated and humidified
- precise Fio2
- reduces work of breathing
- alternative for those who can’t tolerate BIPAP
What type of patient can use a nasal cannula
Stable patients or acute care patients
Who would use an oxymizer
Patients who are discharged
Who would use an simple mask
Post op or mouth breathers
Who would use an oxymask
More complex patients
Who would use an air entrainment mask
COPD patients
Who would need a non rebreather mask
Pts who need high amounts of Fio2 the quickest ( Emergency situations)
Who would use a high flow nasal cannula
Pts who are long term, have secretions, COPD, Asthmatics
Who would use an air entrainment nebulizer
Anyone who needs cool aerosolation to reduce upper airway inflammation seen in stridor, post extubation, croup, upper airway edema
What should you do before entering a room
Wash hands, don gloves, verify physician order and review chart
What should you do when in the room with patient
Verify pt name, DOB, and MRN
Introduce yourself
what is the normal HR
60-100
Normal Spo2
93-98%
Normal RR
12-20
When calculating vitals what do you do
Count for 15 seconds and multiply the number by 4
