Transfusion of blood and fluids during transport

Have you ever had to give patients cold blood or fluids during transport?

Bleeding patients may require transport within or outside the hospital for treatment. But if doctors do not have access to transportable blood and fluid warmers, they can feel forced to transfuse cold blood or fluids during transportation.

Transfusing cold blood or fluids should never be an option. Infusing a bleeding patient with cold blood can lead to hypothermia with severe consequences.

Hypothermia not only accelerates blood loss and thereby the use of blood products, it also increases the risk of infection and prolongs hospitalization time up to 20%. 1,2

With larger hospitals and more centralization of specialty treatment the need for blood and fluid warmers that can follow the patient during transport to ensure consistency of premium care is growing.

The °M Warmer System is a blood and fluid warmer designed to go with the patient, so you never have to give cold blood or fluids during transport again.

The °M Warmer System is ideal for blood transfusions during transport

The °M Warmer System is a revolutionary system enabling fast, easy and efficient delivery of warm blood and fluids to the patient – even during transport.

The °M Warmer System can easily travel with the patient anywhere inside and outside the hospital, enabling a continuous flow of warm blood or IV fluids during transportation.
