Respiratory Care (Masks, sounds, etc.) Unit 2

Question 1

Give extra oxygen to someone with COPD. T/F?

Answer 1

False - we don’t want to do this!

Question 2

What are some indications for oxygen therapy?

Answer 2

Hypoxemia/hypoxia, increased work of breathing, increased work of the heart.

Question 3

Hypoxemia - def

Answer 3

low oxygen in the blood.

Question 4

Hypoxia - def

Answer 4

inadequate oxygen getting into the cells.

Question 5

What are some clinical manifestations of Hypoxemia? (HR, RR, BP, SaO2, PaO2, etc.)

Answer 5

Tachycardia, Hypertension, Tachypnea, SaO2 less than 90%, PaO2 (arterial blood gas), less than 60%, Pulmonary Hypertension, Secondary Polycythemia.
Can also include increased work of breathing, confusion/disorentation, lethargy, development of cyanosis.

Question 6

Pulmonary Hypertension - def

Answer 6

Increased pressure in the lungs.

Question 7

Secondary Polycythemia - def

Answer 7

More red blood cells because of the body trying to increase/move around the Hgb.

Question 8

What is pursed lip breathing and what does it help with?

Answer 8

It’s when you purse your lips - inhaling through the nose and then exhaling (with pursed lips) through your mouth. It helps prolong exhalation!

Question 9

Oxygen - it’s okay to smoke around it because Oxygen isn’t combustible. T/F?

Answer 9

False - it is combustible! So make sure no one smokes around it and also make sure there aren’t electrical devices nearby.

Question 10

What are some guidelines for Safe Handling of Oxygen Cylinders?

Answer 10

Check for cylinder color (usually green), check the label, transport in an approved container, do not store near a heat source, etc.

Question 11

What are the E Cylinders filled to? (PSI)

Answer 11

2000-2200 PSI

Question 12

A regulator doesn’t affect PSI. T/F?

Answer 12

No, it does! It is reduced by 50 PSI.

Question 13

Approximately how long will 2-6 liters of oxygen last?

Answer 13

About 4-6 hours.

Question 14

Low Flow Device - def

Answer 14

the oxygen delivered supply only a portion of the inhaled gas. The remainder is pulled from the environment.

Question 15

High flow devices - def

Answer 15

All the inhaled gas is delivered from the system regardless of the patient’s ventilatory pattern.

Question 16

Nasal Cannula - High/Low Flow?, how much does it run at, what percent of oxygen does it give?

Answer 16

Low Flow Device.
Runs at 1-6 Liters of O2.
Delivers approximately 24-44% oxygen. Oxygen concentrations may vary if the patient’s ventilatory pattern is abnormal.

Question 17

Simple Mask - High/Low Flow? What does it run at? What percentage of oxygen does it deliver?

Answer 17

Runs at a flow of 6-10 Liters

Delivers approximately 35-60% oxygen.

Question 18

Partial Rebreather Mask - high/low flow? What does it run at ? How much oxygen does it deliver? What is some basic info about it?

Answer 18

It is low flow. It runs at 6-15 liters.
Delivers approximately 70-90% oxygen.
It collects patients air - They PARTIALLY rebreathe their own exhaled air, and are partially getting O2 from a tank or something similar.

Question 19

Non-rebreather mask - high/low flow? What does it run at ? How much oxygen does it deliver? What is some basic info about it?

Answer 19

Low flow. It runs at 6-15 liters. It delivers approximately 60-100% oxygen. The patient is not rebreathing their own air.

Question 20

Venturi Mask - high/low flow? What does it run at ? How much oxygen does it deliver? What is some basic info about it?

Answer 20

HIGH flow. Delivers a specific FiO2. It uses adapters to create said specific amount. Provided concentrations of 24,28,31,35,40,50, and 55% oxygen depending upon the adapter used.

Question 21

Incentive Spirometry - what is it?

Answer 21

It is when a patient will exhale/suck into an piece of equipment and raise a little bubble. It is indicated for patients with atelectasis (possibly those who had abdominal/thoracic surgery, post op patients with documented acute or chronic lung disease, chest trauma, etc.

Question 22

What are some techniques for Incentive Spirometry?

Answer 22

Draw in a slow, deep breath to maximal inspiration. Hold the breath. Let the breath out slowly. Repeat 15 times every 2 hours.

Question 23

MDI - what is it?

Answer 23

Multi-Dose Inahler. It requires hand-mouth coordination, etc.

Question 24

Small Volume nebulizer - what is it?

Answer 24

Used in acute and long-term care settings, it is what I used as a kid!

Question 25

Don’t worry about vital signs with Small Volume Nebulizer’s - T/F?

Answer 25

False - we should worry about them because the HR can be increased (due to the medication!)

Question 26

What is an Oropharyngeal Artificial Airway?

Answer 26

It is an airway placed in the mouth. It is used to relieve upper airway constriction, a bite block, or to prevent laceration of tongue for the incoherent/seizing patient. It is hard for the alert patient.

Question 27

What is the Nasopharyngeal Artificial Airway?

Answer 27

It is placed through the nose. It relieves upper airway obstruction caused by the tongue and/or soft palate. Better for the alert patient! It should be changed every 24 hours!

Question 28

What are some possible complications of the Nasopharyngeal airway?

Answer 28

Sinusitis (inflammation of the nasal passages), Otitis Media (inner ear inflammation), Nasal Necrosis
