Determination of the Accuracy of a Non-Invasive Continuous Blood Pressure Device
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.

Beskrivelse
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)

Intervention / Behandling |
|---|---|
|
Heart rate and blood pressure determination
All subjects have the same conditions (T-line, blood pressure cuff, and radial artery catheter), in order to compare them within-subjects.
|
The T-line device will be placed over the contralateral (from the radial artery catheter) radial artery at the distal wrist.
To attach the device, a single-use sterile sensor is placed over the radial artery and the device then gently clamped around the wrist to incorporate the sensor.
After a ten-minute stabilization period, data will be recorded every ten minutes during the first two hours of surgery, or until the patient is placed on cardiopulmonary bypass.
The T-line device will then be removed.
This procedure will be repeated, for a second two-hour period, in the ICU postoperatively.
