|
What types of patients need 100% Oxygen?
|
- someone who has recently been exposed to smoke inhalation such as a burn victim
- code situation (no pulse/no breathing) - patient having a seizure - pulmonary edema patient |
|
|
What are some symptoms associated w/ a cardiac patient?
|
- sweaty, clammy, shortness of breath
|
|
|
What type of O2 setup should a stable cardiac patient be given?
|
- 4 L nasal cannula
|
|
|
What type of O2 setup should an unstable cardiac patient be given?
|
- high flow device w/ atleast 36% FIO2 (venturi setup)
|
|
|
What is a "cool mist" therapy? What type of patient would be given a "cool mist" therapy?
|
- aerosol treatment
- post extubated patient; irritated skin can cause swelling |
|
|
What should be recommended if a CO patient is not responding well to non-rebreather mask?
|
HBO therapy
|
|
|
What type of O2 setup should the chronic lung patient w/ irregular ventilation be given?
|
precise controlled low FIO2; venturi mask at 24%-28%
|
|
|
What type of O2 setup should a stable COPD patient be given?
|
- nasal cannula (comfort for long term use)
|
|
|
What type of O2 setup should a pneumonia patient w/ low PaO2 be given?
|
- nasal cannula at 5 LPM
- moderate FIO2 concentrations - try simple mask |
|
|
What type of O2 setup should be given to a patient w/ thick, tenacious secretions?
|
- high-flow setup w/ aerosol set to 40%
|
|
|
What type of O2 setup should a patient w/ mild facial burns w/ smoke inhalation be given?
|
- high FIO2
- possible aerosol face tent |
|
|
What are the indications for low flow devices?
|
- VT 300-700ml
- RR lower than 25 BPM - consistent, regular, ventilatory pattern |
|
|
At what liter flow should O2 be accompanied by humidity?
|
- 4 liters of flow or more
|
|
|
What is the flow range for a nasal cannula?
|
- up to 6 LPM
- flows greater than 6 LPM do not significantly increase FIO2 due to a filled anatomic reservoir |
|
|
What is important to know in regards to using a nasal cannula?
|
- FIO2 is variable depending on patient ventilatory pattern
|
|
|
What is the FIO2 for a nasal cannula at 1 LPM? 2 LPM? 3 LPM? 4 LPM? 5 LPM? 6 LPM?
|
estimates rule ( 4* liter flow) + 20
1 LPM= 0.24 2 LPM= 0.28 3 LPM= 0.32 4 LPM= 0.36 5 LPM= 0.40 6 LPM= 0.44 |
|
|
What are the FIO2's of a nasal catheter similar to? How often should it be changed?
|
- similar to nasal cannula
- should be changed every 8 hours (rotating nares) to prevent skin breakdown |
|
|
What is the FIO2 range for a simple O2 mask? Liter flow range?
|
- 0.35-0.55
- 5-8 LPM |
|
|
What happens if a patient w/ a simple mask is given less than 5 LPM?
|
- may allow CO2 to build up
|
|
|
Why will a patient w/ a simple mask set to 6 LPM have a higher FIO2 than a patient w/ a nasal cannula at 6 LPM?
|
- due to increased resevoir of simple mask
|
|
|
What FIO2 can a partial rebreather mask deliver?
|
- FIO2's up to 0.60 depending on ventilatory pattern
|
|
|
What is the flow range for a partial rebreather mask?
|
- 8-10 LPM (must be adequate to prevent bag from collapsing)
|
|
|
What FIO2 can a non-rebreather mask deliver?
|
- 0.70-1.0 depending on ventilatory pattern
|
|
|
What is the flow range for a non-rebreather mask?
|
- 8-10 LPM (must be adequate to keep bag from collapsing on inspiration)
|
|
|
How does a non-rebreather mask differ from a partial rebreather mask?
|
- one-way valve between bag & mask
- 2 one-way valves on exhalation port (1 removed for safety) |
|
|
What is a transtracheal catheter?
|
- teflon catheter inserted directly into trachea
- less O2 flow is needed to maintain adequate oxygenation (as little as 0.25 may be needed) - anatomic reservoir now includes part of trachea |
|
|
What are 2 types of O2 conserving systems?
|
- oxymiser cannula & oxymiser pendant
- increases FIO2 & allows primary tank to last longer |
|
|
What must the total system output (device) be to meet all patient's demands for a high flow system?
|
- total system output must be at least 3 times the patient's minute volume
- this is due to the 1:2 I:E ratio (all inspiration occurs during first 1/3 of minute volume) - normal peak flows are about 3 times the minute ventilation |
|
|
What does a high flow system deliver?
|
consistent, predictable, & measurable FIO2
|
|
|
What is the criteria for a high flow system?
|
- patient doesn't meet criteria for low flow system
- VT not 300-700ml - RR in excess of 25 BPM - irregular or inconsistent ventilatory pattern |
