What is the Difference between Clean, Disinfect and Steril

A

Clean= Only removed dirt matter
Disinfect= 3 levels.

Q

MIP vs. MEP
Normals?
How is the test performed?

A

Normals:
MIP Males: -125 cmH2O
MIP Females: -90 cmH2O Inadequate= Less than -20 to -25 cmH2O

MEP Males: 230 cmH2O
MEP Females: 150 cmH2O
Inadequate= Less than 40- Requires ventilation

How it’s performed= MIP and MEP are done 3 times each to obtain the best of the 3 scores.

(Note: must have nose clips on, and it will feel as if the pt cannot breathe into the tube or suck air from the tube)
MIP: Pt blows all the air out of their lungs and takes a deep breath in on the manometer.
MEP: Pt takes a deep breath in and blows all their air out into the manometer

Q

Slow Ventilated Capacity
Abbreviation and reasoning why we do it?
How we do it?
What pt. do we do this on?

A

SVC, Testing how much air pt. can get out in one breath.

  1. Deepest breath in
  2. Blow all the air out until lungs are empty either slowly or quickly (preferably slowly) into Spirometer

Done with pt. who have neuromuscular diseases to monitor lung function

Palpation= Touching the pt. chest symmetry, trachea position, skin temp, lumps/bumps, tactile fremitus (pt says “99” we feel on top/middle/low back the vibrations

Percussion= Feeling with side of hand in between ribs for dull or hyper-resonant vibrations

A

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

Percussion: Dull

Auscultation: Adventitious breath sounds with either no sound or Crackles (Rales). Loud Bronchial breath Sounds

191
Q

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.

A

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

Q

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?

A

Bourdon Gauge as it’s not gravity dependent like a Thorpe Tube.

Q

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?

A

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

Q

Why is a minimum of 5LPM on a simple mask required?

A

Because CO2 can back up in the reservoir bag.

200
Q

Why will an air entrainment mask never deliver 100% O2?

A

The air entrainment mask mixes with ambient air and O2 by the different FIO2 settings

201
Q

Explain the difference between a High Flow and a Low Flow O2 delivery system and give an example of each

A

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
Q

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?

A

Turn up the flow rate

203
Q

What oxygen delivery device would you recommend for a pt. who has just been successfully resuscitated and is spontaneously brathing?

A

Non-Rebreather with as much oxygen as possible as they may have been out of O2 during the resuscitation

204
Q

List 3 factors that will affect he FIO2 delivered by a low flow oxygen System,

A

Inspiratory Flow rate, Tidal Volume, Respiratory Rate
