Patient Setups

These settings are provided as a guideline for initial settings.

Individual patients may require further adjustments based on

their own conditions. Existing protocols within your facility

should always supersede these baseline recommendations.

Please reference the TiControl guide on page 24

for correlating Ti Max/Ti Min settings appropriate

for each disease state and adjust based on

patient’s resting respiratory rate.

Patients with obstructive lung disease have chronic airﬂow

limitation. These patients have particular difﬁculty exhaling

air, which leads to air trapping and hyperinﬂation. These

patients require a longer exhalation, which often leads to

asynchrony with standard bilevel settings.

The recommended settings use a faster rise time to ensure

that the lungs are ﬁlled quickly, and a high cycle sensitivity

to provide an earlier cycle to exhalation. The rapid inhalation

and prolonged exhalation will help to prevent auto-PEEP

and preserve synchrony.

Obstructive lung disease

Patients with restrictive lung disease have a difﬁcult

time maintaining the inhalation phase long enough to

ensure adequate tidal volume and gas exchange. This

can be caused by a physical restriction of the lungs or

by neuromuscular weakness.

The recommended settings use a low cycle sensitivity and

a longer Ti Min time to provide a longer inhalation time to

help increase tidal volume and gas exchange.
