Nasal Cannula
1. Type of flow?
2. Oxygen concentration?
3. What is it attached to?

All Low flow devices have ______ FiO2 stability
Variable
Nasal Cannula Problems
º Skin irritation
º Nasopharyngeal irritation
º No gas flow felt from cannula
º Humidifier pop off: weird continuous sound
º Upper lip soreness from nasal cannula straps

The highest flow of oxygen given to a patient is around...
FiO2=40%
FiO2 is measured in (TEST)
decimals even though it is technically the same as oxygen concentration. Units be careful!
Oxygen Concentration is measured in (TEST)
percent
Nasal Catheter
1. Type of flow?
2. Oxygen concentration?
º Not in hospitals anymore
1. Low Flow
2. 22-45% at 1/4 to 5 L/min

Nasal Catheter Problems
º Invasive
º Gagging is common
º Chemical ammonia can happen
º Gastric distention: When a patient is swallowing excessive air into their stomach.
º Gastric distention can lead to vomiting. The acid from your stomach can go INTO the patients lungs and cause chemical pneumonia
º Complicated to install due to different uvula's in different people.
º Not good for people with excessive mucus

What does it mean by a "Pulse demand oxygen system?"
Device will only give a "pulse" of oxygen when a person is inspiring.
Transtracheal Oxygen (TTO)
1. Type of device?
2. How much oxygen does this system save?
3. How is it installed?
4. Invasive or non invasive?
5. How is it cleaned?
1. Oxygen conserving device, Low flow mask
2. Around 54 to 59%
3. Surgery of the TTO :2nd/3rd tracheal ring
4. Invasive
5. Using saline solution

Beneficial: People who do not want to be seen with a nasal cannula. They can just wear a turtle neck

Reservoir Nasal Cannula 1. Type of device? 2. How much oxygen does this system save? 3. How is it installed? 4. Invasive or noninvasive? 5. How is it cleaned?1. Oxygen conserving device, Low flow mask -Pendent version -Mustache version 2. Saves 50 to 75% O2 3. Into the nose and around your ears. Almost like glasses for your nose. 4. noninvasive 5. Doesn't need to be cleaned. Obtrusive Appearance: You will stand out if you wear this.Reservoir Nasal Cannula Problems:Pendant version: Extra weight Ear/Face DiscomfortPulse Demand Oxygen Delivery Systemº Delivers oxygen only during inspiration º Can be used with nasal cannulas, nasal catheters, and TTO catheters º Delivers flows equivalent to 1 to 5 L/min ºLow flow maskSimple Oxygen Mask 1. Type of device? 2. Flow rate? 3. Oxygen concentration? 4. Good for?1. low-flow devices -cover patient's nose and mouth 2. flow rate at 5-10 L/min 3. deliver 35% to 60% oxygen 4. Emergencies º not common use, and are use for short-term oxygen therapySimple Oxygen Mask Problemsº Uncomfortable º Have to remove when earing º Blocks vomit when unconscious: Can lead to acid in lungsPartial Rebreathing Mask 1. Type of device? 2. Flow rate? 3. Oxygen concentration? 4. Key to using this bag1. Low flow device 2. 10 L/min 3. 40-70% 4. Bag has to be 1/3 to 1/2 full º Little holes in the simple mask for room air º Reservoir bag connected to O2 gas Simple Oxygen mask+ Reservoir bag= Partial Rebreathing Mask!Nonrebreathing Mask 1. Minimum flow rate? 2. O2 Concentration? 3. Low or High FIO2? 4. What is this mask similar to? 5. Type of mask?º Looks extremely similar to the partial rebreather mask º Gives a higher amount of O2 than the partial rebreather mask. º It has two to three valves for O2 placement. Mostly 3 valves because if there are only 2 valves the patient can suffocate from no external air if the O2 tanks stop working 1. 10 L/min, or else it will collapse on inspiration 2. 60-80% 3. High 4. Simple mask 5. Low flowProblems with reservoir masksº Device displacement ---Patients who are confused or claustrophobic º System leaks and obstructions ---Flowmeter not on or leaking º Improper flow adjustment ---Humidifier Obstruction º Skin irritation ---Straps may hurtOxymaskºNeed to use pulse oximeter with it. (Inaccuracy) ºDangerous to sensitive people Ex: COPD patients (can go from 20 to 90% O2)The average adult peak inspiratory flow during tidal ventilation is approximately___________times the minute volume.threeMinute VolumeThe amount of air breathed in during each respiration multiplied by the number of breaths per minute. Tidal volume times Respiratory rate
