TCM5 FLEX transcutaneous monitor supports your care of critically ill patients

The TCM5 FLEX transcutaneous monitor is a compact, easy-to-use solution that delivers accurate and continuous measurement of oxygenation (tcpO2) and ventilation (tcpCO2) status in neonatal, pediatric and adult patients in the ICU.

System defined limits of site time vs. temperature help reduce the risk of harm from the heated electrode.

Parameters

Pulse Oximetry: 
Pulse
The rhythmic dilation of an artery that results from beating of the heart. Pulse rate is the rate at which the heart beats per minute (bpm). The measurement is based on the optical detection of a peripheral flow pulse. The volume of arterial blood in the tissue (and hence, the light absorption by that blood) changes during the pulse. This is also known as plethysmography.
, SpO2

Oxygen saturation, reported as a percentage of oxyhemoglobin (HbO2) on a total of oxy- and deoxy-hemoglobin. It is expressed by the formula: HbO2 / (HbO2+deoxyhemoglobin). It is measured non-invasively by pulse oximetry, an absorption-based technique. The relationship between SpO2 (measured by pulse oximetry) and pO2 is given by the oxygen dissociation curve.

Transcutaneous blood gas: 
tcpCO2
Transcutaneous partial pressure of CO2 (carbon dioxide) 

tcpCO2 is measured through a sensor placed on the skin surface. A tcpCO2 sensor uses the Stow-Severinghaus principle. CO2 reacts with water and forms carbonic acid and dissociates into H+, which is interpreted through a pH glass element. After conversion, the sensor algorithm generates a tcpCO2 in mmHg (millimeters of mercury) or kPa (kilopascals)
 
, tcpO2
Transcutaneous partial pressure of O2 (oxygen) 

tcpO2 is measured through a sensor placed on the skin surface. 

A tcpO2 sensor is based on the Clark principle; O2 diffuses through the skin and the membrane to a Platinum cathode. After conversion, the sensor algorithm generates a tcpO2 in mmHg (millimeters of mercury) or kPa (kilopascals).

A transcutaneous monitor that helps you focus on patient care

The TCM5 FLEX transcutaneous monitor has an intuitive user interface and built-in tutorials that make it easy to set up, learn and use.

Compact and practical, the TCM5 FLEX monitor comes with a color touchscreen. Clear on-screen messages give you an immediate overview of measured parameters supporting patient care.

A clearly visible alarm bar on top of the monitor and on-screen icons alert you to changes in patient status. Real-time trending measurements allow for immediate clinical intervention to critical changes in patient status. [1]

Transcutaneous monitor with reliable sensors

The surgical steel protected sensors measure tcpO2 and tcpCO2, SpO2 and pulse rate, delivering consistent and reliable results. The sensors have a variety of fixation options helping to improve patient comfort.

Automatic calibration of the sensor reduces preparation time and improves workflow.

A dedicated sensor cable spool makes cable management easy, keeping your department clutter-free.

New for 2022: Improved sensor head design with better protection of the cable and greater pull strength.

Transcutaneous monitoring enables careful monitoring of the neonate

Transcutaneous monitoring – or continuous, non-invasive monitoring – of tcpO2 and tcpCO2 can detect changes in the oxygenation and ventilation status of neonates. [2, 3, 4, 5] 

Transcutaneous monitoring complements arterial and capillary blood sampling. You can reduce the number of blood samples and limit unnecessary handling of the infant, while ensuring careful control of your patient. [3, 4, 5, 6, 7]

The TCM5 FLEX transcutaneous monitor helps reduce patient discomfort with system defined limits of site time vs. temperature to reduce the risk of harm from the heated electrode by predefined combinations of time and temperature.

Continuous transcutaneous monitoring of patients in the ICU

Patients with acute respiratory failure and respiratory pump insufficiency are often treated with mechanical ventilation. Real-time monitoring offers a reliable approach to titrate ventilator settings without repeated blood sampling.[8, 9, 10, 11]

Unlike blood gas sampling, transcutaneous monitoring provides continuous information on CO2 levels allowing for proactive, rather than reactive ventilator adjustments.[10]

Transcutaneous monitoring improves patient care by reducing the need for blood samples, thereby reducing patient discomfort.[7, 10]

Weaning and extubation decisions may be made based on tcpCO2 measurement alone.[10]

By being able to view continuous data instead of having to rely on periodic blood gas analysis, I feel fully confident in my ability to be precise and accurate so I can provide a higher level of care.
