What is the blow by technique?
Used when a pt cannot tolerate a mask. Direct the aerosol toward the pt nose and mouth. A few inches away from face
107
Do we adjust neb dose for infants? Why?
No. Their airways are smaller, they breath faster, they have lower minute ventilation and they breath through their nose so less particles get deposited into their lungs

129
Tank Duration Equation and Calculation (with and with out buffer)

Water vapor in air in relation to the temperature. Often described in weather forecasts as a %
134
Isothermic Saturation Boundary (ISB) What is it? Where is it?
The point when inspired gas becomes fully saturated to 100% relative humidity at body temperature. Takes place 5 cm below the carina
135
2 Primary Reasons for Humidity and 4 Secondary Reasons
1. Humidifying Medical Gas 2. Overcoming humidity deficit when upper airway is bypassed 1. Thick, bloody secretions 2. With expired Tidal Volume less than 70% of the delivered tidal volume 3. Body temp below 32'C 4. With high spontaneous Minute Ventilation
136
4 Hazards of Humidity
1. Temp= higher Temp the more vapor (vice versa) 2. Surface Area= Greater Surface area between water and gas the more evaporation can occur 3. Contact Time= The longer gas is in contact with water the more evaporation can occur 4. Thermal Mass= the greater the mass of water & the heater, the better to transfer heat

188
Critical Thinking: Your pt. has a RLL pneumonia. What would be the expected assessment findings that would be evident with pneumonia? (Inspection, palpation, percussion, auscultation)
Inspection: Pt may be in tripod stance with an increased work of breathing and nasal flaring. This would indicate shortness of breath and respiratory distress. Palpation: Increased tactile fremitus in the posterior RLL Percussion: Dull percussion Auscultation: Would hear adventitious breath sounds in the RLL. The Chest symmetry would differ between the two lungs. There would be louder bronchial breath sounds on the RLL. Would hear crackles (rales), Rhonchi, wheezing or pleural friction rub through the stethoscope
189
Critical Thinking: Why do some patients have diminished breath sounds? List 3 diseases or disorders that pt. may exhibit diminished breath sounds.
Can be due to trauma to the lung, a disease of the lung tissue or infection present in the lungs. 1. Tension Pneumothorax 2. Pleural Effusion 3. Neuromuscular Diseases such as Guillain Barre or Myasthenia Gavis
190
Critical Thinking: Your pt. has atelectasis document on chest x-ray. What would be expected assessment findings if the atelectasis is located in the Left Upper Lobe. (Palpation, Percussion, Auscultation)
Palpation: Decreased fremitus. Symmetry of rise and fall compared to Right Lung would be lesser. Trachea would be shifted toward the left side Percussion: Dull Auscultation: Adventitious breath sounds with either no sound or Crackles (Rales). Loud Bronchial breath Sounds
191
Critical Thinking: Your pt has a long standing history of COPD. He complains of increasing shortness of breath and a productive cough. During physical exam of the chest, you notice a hyper resonant percussion note with decreased fremitus over most of the lung fields except for the RLL which has a dull percussion note and increased fremitus. Identify a possible explanation for these differences in your findings. Part 2: Based on your findings, describe what you would expect to hear on auscultation over the RLL.
The patient has hyper resonant percussion with decreased fremitus in majority of the lung fields because of the pt. history with COPD, However, the RLL has dull percussion with increased fremitus which indicates the pt. has consolidation or Pneumonia Part 2) You would hear crackles, Rhonchi, wheezing as well as abnormalities when performing the Whispering Pectoriloquy, egophony and bronchophony tests
192
Critical Thinking: Your pt. A 34 year old man, presents to the ED with left sided chest pain and shortness of breath. It is suspected that he has a left sided pneumothorax. What findings on a physical exam would help establish the diagnosis? (Inspection, Palpation, percussion, Auscultation) part two) what tests should be performed to confirm the Dx?
Inspection: There would be signs of respiratory distress by either nasal flaring, tripod stance, tachypnea, irregular RR, low O2 rate and may be 1-2-3 word dyspnea. There would be discomfort and pleuratic chest painn in the location of the pneumothorax. Palpation: Decreased tatile fremitus. The Trachea should be shifted away from the side of pneumothorax. Percussion: Abnormal percussion sounds would be Hyper Resonant Auscultation: Diminished breath sounds with no adventitious breath sounds Part two) A Chest x-ray should be completed to confirm the presence of air in the pleural cavity.
193
Why is it important to crack a cylinder before use?
To clean debris and dust that may have built up in the valve stem
194
Critical Thinking: Your patient needs to go the imaging department for a CT scan. He is currently using oxygen. What will you need to gather to ensure he can continue to use oxygen for the transport?
A Grab and Go oxygen Tank or a smaller portable oxygen tank
195
Why are the separate pipping zones for gas supply systems in hospitals?

197
Would you want to use a Bourdon Gauge or a Thorpe Tube if the O2 tank you will be using will be laying on its side, secured under the stretcher for transport?

198
Critical Thinking: A 60 year old female patient with COPD is admitted to the ED via ambulance wearing a NRB mask at 10 LPM. She was alert and awake when the ambulance arrived at her home, she is now extremely lethargic and somnolent. The ED physician order you to change the O2 delivery device to a nasal cannula at 3L. Briefly explain the most likely cause of the Pt. Lethargy. Part two: The Physican requests that you change the device to a Venti mask at a comparable FIO2 as the nasal cannula was set to. What would the FIO2 be set at on the Venti mask?
There is a possibility that the pt. has depression ventilation due to her COPD. RT would need to determine the CO2 levels to verify if this is the issue as it only affects a small portion of COPD patients. More than likely; the cause is due to the patient receiving too much Oxygen with the Non-Rebreather mask. This caused the Nitrogen to wash out which caused poor gas exchange and an increased work of breathing. Part two: FIO2= 35%. Pt was on a 3L nasal cannula. Venti mask offers 31% and 35% options, going a little above the equivalent to the nasal cannula will allow the RT to decrease the FIO2 as the patient progresses
199
Why is a minimum of 5LPM on a simple mask required?
Because CO2 can back up in the reservoir bag.
200
Why will an air entrainment mask never deliver 100% O2?
The air entrainment mask mixes with ambient air and O2 by the different FIO2 settings
201
Explain the difference between a High Flow and a Low Flow O2 delivery system and give an example of each
High Flow: Allows us to meet or exceed the pt flow demand, it mixes O2 and air to create a precise FIO2 - Air Entrainment Mask Low Flow: Provides a portion of the total patient flow, The low flow system adds to the patient's own flow, which means it is always diluted with air - nasal cannula
202
Critical Thinking: You observe a pt. wearing a non-rebreather mask and note that the bag completely deflates with each inspiration. What actions, if any, should be taken?
Turn up the flow rate
203
What oxygen delivery device would you recommend for a pt. who has just been successfully resuscitated and is spontaneously brathing?
Non-Rebreather with as much oxygen as possible as they may have been out of O2 during the resuscitation
204
List 3 factors that will affect he FIO2 delivered by a low flow oxygen System,
Inspiratory Flow rate, Tidal Volume, Respiratory Rate
