ICU Medical 52515-15 - CATHETER, TDQ CCO HEP/YELLOW, 6 EA/CS
TDQ Continuous Cardiac Output (CCO) Catheter
TDQ provides accurate CCO measurements, as well as Central Venous Pressure (CVP), Pulmonary Artery Pressure (PA) and Pulmonary Artery Occlusion Pressure (PAOP) parameters. TDQ also allows for venous and mixed venous blood sampling and pulmonary artery temperature measurement.
- Intermittent and continuous thermodilution cardiac output measurements.
- PA temperature measurement, CVP, PAP, and PAOP monitoring.
- Venous and mixed venous blood sampling capability.
The TDQ Catheters are part of a complete line of pulmonary artery catheters offered with no natural rubber latex components in order to reduce the risk of patient latex allergy or hypersensitivity, without compromising performance. A recent study of antilatex IgE antibodies in blood donors has shown that the prevalence of latex sensitivity may be as high as 6-12%1 or up to 37 million people in the U.S. alone.
The problem - latex allergies.
Latex allergy or hypersensitivity occurs when the bodys immune system reacts to proteins found in natural rubber latex. A Type I systemic reaction is an immediate hypersensitivity reaction moderated by the development of IgE antibodies to specific proteins in latex, causing a serious and potentially lethal event.
A recent study of antilatex IgE antibodies in blood donors has shown that the prevalence of latex sensitivity may be as high as 6-12%1 or up to 37 million people in the U.S. alone. Once sensitized, most individuals are
asymptomatic and unaware of their antibody status;1,2 therefore, clinicians cannot assume that any patient is free of latex allergy.
Consider the following case involving a 63-year-old patient undergoing surgical resection of an 11 mm abdominal aortic aneurysm:
After insertion of radial artery and pulmonary artery (PA) catheters and prior to induction of anesthesia, the anesthesiologist noted that the patient experienced a significant decrease in systolic arterial blood pressure from 120 to 70 mmHg. Surgery was postponed to the following day in spite of the risk of rupture of the aneurysm, to identify the cause of this apparent systemic allergic reaction. On the second day, the PA catheter was inserted when the patient immediately complained of dyspnea, the SaO2 decreased from 93% to 79%, and pulmonary auscultation revealed bronchospasm. Tracheal intubation was performed, the patient was treated with phenylephrine and epinephrine, and crystalloids were used for volume expansion to restore hemodynamic status. This patient had not reported any previous history of sensitivity to latex.
