Setting Up the Z Vent Ventilator

Never use O
2
flows > 10-12 liters/min. Flows greater than this can cause the baseline
pressure to drift, waste oxygen, and may cause an INCOMPLETE EXHALATION
alarm.
Warning!
Always monitor the patient's oxygenation using a pulse oximeter. The O
2
flow from a
concentrator or other O
2
source may not be adequate to achieve the desired SPO
2
target. Failure to follow the Instructions and WARNINGS provided with the O
2
Reservoir could result in an adverse effect on the patient.
Note:
Due to the slight difference between the densities of air and O
2
, the tidal volume will
decrease slightly as O
2
is entrained. The worst case is a < 10% decrease in tidal
volume when the entrained O
2
results in FIO
2
of 100%.
The table below shows both the affect on tidal volume and the resultant FIO
2
supply
rate.
Bacterial/Viral (BV) Filter
If the ventilator will operate in an environment where the patient is at risk from cross
contamination or airborne pathogens, you may choose to attach a BV filter (See Chapter 6,
“Operating Environments” for more information on this filter).
Chemical/Biological C2A1 Filter
If the ventilator will operate in a contaminated environment, you may choose to attach a
chemical/biological C2A1 filter obtained from a Chemical/Biological Filter supplier.
