Oxygen Delivery Methods Flashcards
1
Q
Flow-by Indications
A
- Initial triage
- Well tolerated by most
- FiO2 25-40%
2
Q
Flow-by Considerations
A
- Short term only
- Doesn’t provide high flow
- Not always effective if patient non-compliant
3
Q
Mask Indications
A
- Allows simultaneous assessment and treatment
- Good for obtunded patients
- FiO2 50-70% (if properly fitted)
4
Q
Mask Considerations
A
- Awake patients may not tolerate
- May rebreathe CO2 if mask tightly fitted
- Dangerous increase in humidity and temp may occur
5
Q
Hood Indications
A
- Patients who can’t have/won’t tolerate nasal lines or too big for O2 cage
- Usually well tolerated
- FiO2 30-40%
6
Q
Hood Considerations
A
- May not be well tolerated in cats
- May cause hyperthermia
- Excessive CO2, moisture and humidity may cause distress to compromised patient
7
Q
Cage Indications
A
- Good for stressed patients who won’t tolerate other methods
- Good option for small animals/cats
- Minimally invasive
- Convenient
- FiO2 <90%
8
Q
Cage Considerations
A
- Lack of direct access
- Cant hear patients (care with unstable cardiac or upper respiratory obstruction patients)
- Loss of O2 when door opened
- Expensive
- Hot and humid
- Can take a while for FiO2 to build up
9
Q
Nasal Indications
A
- Good long term option
- Simple to place
- Mostly well tolerated
- FiO2 40-70%
10
Q
Nasal Considerations
A
- May not be tolerated in some as can be irritating
- Cannot be used in some cases (increased ICP, coagulopathies)
- Can cause epistaxis (nasal bleeding) if overzealous with placement
11
Q
Intra-tracheal Indications
A
- Upper airway obstruction
- Fairly well tolerated in sedated/anaesthetised/severely dyspnoeic patient
- FiO2 40-60% or up to 100% on ventilator
12
Q
Intra-tracheal Considerations
A
- Labour intensive
- Technique/training required
- Need sedation/induction drugs
- Potential for intro of bacteria into lungs
- Expensive
