O2 Therapy/Mechanical Ventilation

Question 1

How much O2 in atmosphere?

Answer 1

21% O2

Question 2

Nasal Cannula

Answer 2

-24-44% o2
-1-6L

Question 3

Reservoir Cannula

Answer 3

-retains exhhaled air

Question 4

High Flow Cannula

Answer 4

-1-15L w/ humidification
-24-75% o2
-not harsh on nose

-30-70%
-6L minimum to brevent rebreathing

Question 6

Face Tent

Answer 6

-for mouth breathers or facial trauma
-8-15L
-21-40%

Question 7

-liquid medicatitons into mist
-must be able to see mist
-8-15L
-21-60%

Question 8

Venturi Mask

Answer 8

-color coded

Question 9

Nonrebreathing Mask

Answer 9

-highest 02
-75-100%
-8-15L
-bag must be 1/3-1/2 full
-might be close to intubation

Question 10

Tracheostomy Mask

Answer 10

-straight into tracheostomy tube
-35-60%
-10-15L

Question 11

High Flow humidification Systems

Answer 11

-up to 60L
-up to 100% o2
-humidified and warmed air

Question 12

Mechanical Ventilation

Answer 12

-meet physiological needs of pulmonary system

1. Rrespiratory failure
2. Protection of airway and lung
3. Relief of upper airway obstruction
4. Improvement of ulmonary toilet (unable to clear airways)

Question 13

Paradoxical Breathing

Answer 13

-diaphragm fatigued from working hard
-must be inubated

Question 14

Ventilator Settings to Know

Answer 14

-mode of ventilation
-FiO2: o2 concentration being administered (>60 concern)
-PEEP

Question 15

Ventilator Patient Data to Know

Answer 15

-Minute ventilation
-respiratory rate

Question 16

PEEP

Answer 16

-Positive End Expiratory Pressure
-resisdual pressure in alveoli after exhalation
-pressure required to inflate alveoli and prevent collapse

Low PEEP 3-5: normal
Moderate PEEP 5-15: treat refractory hypoxemia
High PEEP >15: severe lung injury
-put pressure on IVC and decreased CO

Question 17

Mode of Ventilation

Answer 17

-how breath is delivered

1. Assist-Control
2. SIMV and Pressure Support
3. Pressure Support

Question 18

Assist-Control

Answer 18

-non weaning: breathing for patient
-rate and tidal volume pre-set
-patient can trigger breaths with pre-set tidal volume

Question 19

SIMV

Answer 19

-synchronized intermittent Mandatory Ventilation
-Weaning mode: starting to take them off
-rate and tidal volume pre-set
-patient can trigger breaths with pressure support instead of pre-set tidal volume

Question 20

Pressure Support Ventilation

Answer 20

-weaning mode: 0-30cmH20 (10 normal)
-applies to spontaneous breaths
-tidal volume not pre-set
-NOT air, only pressure

Question 21

CPAP

Answer 21

-constant positive pressure applied in airways
-noninvasive ventilation

Question 22

BIPAP

Answer 22

-Bi-level pulmonary airway pressure
-noninvasive ventilation
