Non Invasive Managment

Question 1

Non-invasive vs invasive ventilation types

Answer 1

NIV: CPAP, HFNC, BIPAP
Invasive: ETT, tracheostomy,

Question 2

What are certain patients that may benefit from non-invasive ventilation

Answer 2

COPD exacerbation, cariogenic pulm edema, obesity

Question 3

Indications for HFNC

Answer 3

Hypoxic RF, post-extubation hypoxia, acute pulm edema, DNI

Question 4

When is NIPPV indicated

Answer 4

COPD exacerbation, CHF exacerbation, post-op

Question 5

What is the main goal of NIPPV

Answer 5

Reduction in Inspiratory muscle work and avoidance of respiratory muscle fatigue

Question 6

Indications for CPAP on NIPPV

Answer 6

Hypoxic not hypercapnic patients, improves alveolar edema and increases functional residual capacity

Question 7

What is the PAV (positive airway ventilation) (Trilogy) on NIPPV

Answer 7

Delivers Inspiratory pressure proportional to the patients effort. Based on patient generated volume and flow. No present volume or pressure

Question 8

What is AVAPS on NIPPV

Answer 8

Average Volume Assured Pressure Support. Can set a tidal volume along with pressures.

Question 9

Who are good vs bad candidates for NIPPV

Answer 9

GOOD: Able to protect airway, control secretions, awake and alert, cooperative
BAD: unstable hemodynamics, uncooperative, unable to protect airway, facial trauma, GI bleed, aspiration

Question 10

What are the disadvantages of NIPPV

Answer 10

Slow gas exchange, gastric distention, air leak, skin/eye irritation, aspiration
