Details about TCM CombiM Transcutaneous monitor

The tcpO2 measurement, a differentiating feature of the TCM CombiM monitor, is a crucial parameter for patients in neonatal intensive care to avoid the risk of hyperoxia and its effects (eg. retinopathy in preterm babies). Indeed for high oxygenation rate, where SpO2 is not any more accurate, tcpO2 carries on providing a precious information concerning oxygenation of the tissue.
The TCM CombiM monitor combines an enhanced ready-to-use function with a unique gold-plated sensor technology in the tc Sensor 84 and tc Sensor 54, making it highly reliable, stable and robust. Real-time trending of measured parameters is displayed ensuring fast and immediate clinical intervention to critical changes.
The TCM CombiM monitor utilizes various communication protocols to interface with any patient monitoring system and PC.
