TCM5 BASIC transcutaneous monitor – ready when you are

When it comes to sleep diagnostics, preparation is key. You want all your devices and sensors set up and working properly before the patient arrives.

The TCM5 BASIC transcutaneous monitor helps make preparation easier. Built-in tutorials and a clear, simple user interface simplifies set up, usage and troubleshooting.

Automatic sensor calibration reduces preparation time, supporting your workflow in the sleep lab.


Pulse Oximetry: 
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: 
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)

TCM5 BASIC transcutaneous monitor – at work even in the dark

With a dedicated sleep mode and optional dark screen, the TCM5 BASIC monitor operates in complete darkness. Patients can sleep undisturbed, helping to facilitate accurate measurements.

A transcutaneous monitor delivering advanced connectivity and reporting features

The TCM5 BASIC transcutaneous monitor connects to major patient monitoring systems and polysomnographs enabling you to store, share and manage data and reports.

You can download patient data results to a PC or export them via USB with the integrated data memory that stores up to one year of continuous recorded data.

Connect your TCM5 device and see patient data on one screen 


The ability to connect your TCM5 device to multiple systems means you can see TCM data and other patient data on one screen. Plus, all recordings and data can be collected in one system for later analysis.

Connectivity options

Your TCM5 device connects to a wide range of patient monitoring systems, data management systems, polysomnography systems, and ventilators. Discover all the devices that are compatible with your TCM5 and connect your device today.

Accurate results with transcutaneous sensor

The surgical steel protected sensor offers reliable results even after prolonged use.

Re-membraning needed every 28 days, freeing up valuable time for clinicians.

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


Continuous and non-invasive transcutaneous recording throughout the night

The TCM5 BASIC monitor records tcpCO2, SpO2, and pulse rate continuously all night.

Transcutaneous monitoring plays a very important part in making adjustments of invasive and non-invasive ventilator settings for nocturnal monitoring of ventilation status.
