This protocol will test a new non-invasive device, the T-line, in continuously determining
heart rate and blood pressure in operative and critically ill patients. The accuracy of the
device will be compared to the standard radial artery catheter, as well as to the
non-invasive blood pressure cuff. The T-line will also be compared to the right heart
catheter determining cardiac output in at least 20 patients.
Hypothesis: the T-line device will determine blood pressure and heart rate as accurately as
a standard radial arterial catheter and a blood pressure cuff in perioperative patients.

Inclusion Criteria:
- Age at least 18 years old
- Operative patients expected to require intensive care recovery at OHSU
- Planned or existing intra- and postoperative radial artery catheterization as part of
routine care
- Palpable contralateral (to catheter) radial artery pulse
- Planned intraoperative right heart catheter placement as part of routine clinical
care, in at least 20 subjects of total
Exclusion Criteria:
- No palpable radial artery pulse
- Anatomical abnormalities (skin grafts, cysts, cellulitis) or injuries (scarring,
cuts, burns, bruising) at the sensor site
- An intravenous line placed at the sensor application site or within the
medial/lateral travel range of the sensor
- An AV shunt in the T-line arm
- Known sensitivity to pressure stimuli (dermatographism)
