Simple masks can go up to ___________ liters of O2.
10
Non-rebreather masks can go up to ________ liters of O2.
15 (100% FiO2)
HHFLNC can go up to _________ liters.

PEEP is synonymous with __________.
PEEP
Explain the nomenclature of CPAP and BiPAP.
- CPAP: constant pressure that does not vary with inspiration
- BiPAP: constant pressure with inspiratory force above the constant pressure with inspiration
CPAP is documented as 0/X, which X being the constant force.
BiPAP is documented as Y/X, with Y being the additional force on top of the constant force.
Never use BiPAP in those with __________.
asthma
Why does BiPAP help in COPD?
The inspiratory force helps push the lungs inward, which increases elastic recoil and assists in ventilation.
Pressure support mode is essentially ___________.
CPAP and BiPAP: you define the numbers and the ventilator keeps a positive pressure in the airway
In assist control (aka pressure support), you do not set __________.
a RR; the person must be breathing on their own
Which mode should you start someone on after intubation?
Control mode
You need to paralyze someone while intubating. They will thus not be breathing on their own and you need to set their rate.
In volume control, you set ____________.
the tidal volume
The machine picks the pressure.
Explain the difference between pressure-regulated volume control and volume control.
- Volume control is purely manual with no stops, meaning you set a volume and it will get to that volume no matter how high the pressure gets.
- Pressure-regulated volume control is similar, but it has a pressure cap and will stop at high peak pressures.
Review the extubation criteria.
- Mentally capable (“Show me two fingers.”)
- Cough reflex
- BNP within normal limits
- RSBI 60 - 105
How can you help train people to be extubated?
- Diurese if their BNP is elevated
* Set the ventilator so that they have to breathe on their own rate
