What does the patient feel while using the T-Line® system?
A. The patient is fitted with a snug-fitting wrist restraint that flexes the patient’s wrist in a comfortable position, stabilizing the area of interest and facilitating access to the location of the patient’s radial artery. The T-Line® System gently positions the sensor directly over the radial artery and extracts a calibrated waveform via partial compression of the radial artery supported by the head of the radius. Extensive trials on both current and earlier system prototypes indicated that subjects did NOT experience pain, even after numerous hours of continuous monitoring. Upon cessation of monitoring, patients will typically have a red indentation on their wrist indicating the precise location of the sensor. Testing showed no evidence of a single incidence of a pressure “mark” or skin effect not substantially resolving within 20-30 minutes post-removal. It is important to note that the steady-state compressive force applied by the T-Line® does not occlude blood flow.
