Non-invasive ventilation Flashcards
1
Q
IPAP
A
- Inspiratory positive airway pressure
- higher pressure that is associated with ventilation
- Drives Vt and thus improves minute ventilation
- works similar to PIP in mechanical ventilation
- increase IPAP would increase delivered Vt and decrease the PaCO2
2
Q
EPAP
A
- Expiratory positive airway pressure
- lower pressure associated with oxygenation
- re-established FRC and assists with oxygenation
- works like PEEP in mechanical ventilation
- similar to CPAP
3
Q
What is the goal of NIV application? and what volumes and capacities does it effect?
A
- goal is to increase PaCO2 and decrease CO2
- it effects Vt and IC
4
Q
What is the goal of CPAP?
what capacities and volumes is it oriented towards?
A
- Re-established FRC
- goal is to fix PaO2
5
Q
CPAP
A
- Continuous positive airway pressure
- used for OSA
- Acutely to assist with oxygenation
6
Q
NIV
what is it?
What does it do?
A
- Non-invasive ventilation
- provides 2 pressures.
- IPAP- assists ventilation
- EPAP- assists oxygenation
7
Q
PIP
A
- Peak inspiratory pressure
- can be monitored or set value
- highest inspiratory value
8
Q
Acute condition indications for CPAP/NPPV
A
- Ventilatatory support
- impending resp failure/wean from PPV/post-extubation
- acute respiratory failure (ARF)
- ARDS
- Pneumonia
- Asthma
9
Q
Chronic condition indications for NPPV/CPAP
A
- OSA
- post-polio
- neuromuscular dz
- restrictive lung dz
- COPD
- cystic fibrosis
10
Q
What are some signs and symptoms that would indicate a need for NPPV/CPAP?
A
- Tachypnea- fast respiratory rate
- accessory muscle use
- increased WOB
11
Q
What are contraindications or hazards of CPAP/NPPV?
A
- APNEA
- unable to protect airway
- excessive secretions
- hemodynamic instability
- hemodynamic instability
- agitated or confused
- paradoxical breahting
- upper airway obstruction
- facial trauma
- untreated pneumo
- uncooperative
