|---|---|---|---|---|---|
| show | Do not meet the patients inspiratory flow demands.,Normal inspiratory flow rate is 25 to 30 L/min,Additional flow comes from RA
🗑
|
||||
| show | Nasal Cannula,Nasal,Catheters,Transtracheal Catheters, Simple masks, Partial Rebreathing Masks, Non-rebreathing Mask
🗑
|
||||
| show | Venturi Mask or air-entrainment masks,Aerosol Mask, Face Tent, T-Piece, Trach Mask, Oxygen Tent
🗑
|
||||
| Nasal Cannula and Nasal Catheters | show 🗑
|
||||
| Nasal Catheters position | show 🗑
|
||||
| show | deep insertion can cause air swallowing and gastric distension , must be repositioned every 8 hours to prevent breakdown
🗑
|
||||
| show | Delivers low flow rates (1 to 3 L/min) directly to the trachea through a small incision, Requires less oxygen (lower flows) because the upper airway deadspace is bypassed
🗑
|
||||
| show | Can develop infection and irritation at site and there is a risk of accidental removal, If pt becomes SOB or has increased, Flush with saline, Cleaning Rod, reposition
🗑
|
||||
| Cannulas | show 🗑
|
||||
| show | reservoir just below the nose stores ~ 20 mL of O2 ,allows for lower flows because of increase O2 delivery
🗑
|
||||
| Pendent reservoir | show 🗑
|
||||
| Pendent reservoir limits | show 🗑
|
||||
| Simple masks | show 🗑
|
||||
| Partial Rebreathing Masks | show 🗑
|
||||
| Partial Rebreathing Masks Cons | show 🗑
|
||||
| Non-rebreathing Mask | show 🗑
|
||||
| show | air entrainment mask, mechanical aerosol systems, Gas Injection Nebulizer- need high flow flowmeters, High FiO2 Misty Ox- for FiO2 of .60+ , Blender and titration system
🗑
|
||||
| show | all of the inspiratory flow required by the patient at consistent FiO2s, These devices are normally attached to nebulizers (Venti-mask may or may not be)
🗑
|
||||
| Venturi Mask or air-entrainment masks | show 🗑
|
||||
| show | Increasing flow will not alter FiO2 (precise) The size of the entrainment port determines FiO2 The larger the port, the more RA entrained, the lower the FiO2
🗑
|
||||
| show | Delivers 21-100% FiO2 depending on nebulizer setting, Flow rates of 8 to 15 L/min
🗑
|
||||
| show | On 100% the device will probably not meet flow demands.(>60%) (No air entrained so flow = flowmeter setting)
🗑
|
||||
| show | 21% to 40% depending on nebulizer setting Flow rates of 8 to 15 L/min
🗑
|
||||
| show | Used mainly for patients who can not tolerate a mask
🗑
|
||||
| T-Piece | show 🗑
|
||||
| show | Used on intubated or trached patients
🗑
|
||||
| Trach Mask | show 🗑
|
||||
| show | Adequate flow shown by mist flowing out the exhalation port at all times
🗑
|
||||
| show | 21 -50% at flow rates of 10 to 15 L/min Used mainly on children with croup or pneumonia
🗑
|
||||
| Oxygen Tent Risks | show 🗑
|
||||
| High FiO2's Important Points | show 🗑
|
||||
| show | A restriction, such as a kink, or water in the tubing, causes back-pressure into the nebulizer. This decreases the amount of RA entrained and INCREASES the delivered FiO2. increasing flow on a high flow device will not increase FiO2, only total flow
🗑
|
||||
| show | small, clear plastic enclosures over infant's head or head and upper torso
🗑
|
||||
| Head boxes allows | show 🗑
|
||||
| show | .60 1:1, .50 1.7:1, .40 3:1, .35 5:1,.30 8:1
🗑
