ALPE Technology

The struggle to assess gas exchange

Before ALPE essential it was not possible to acquire clinically relevant knowledge about the pulmonary gas exchange in a rapid and non-invasive way. For many years it has been recognized that this information is highly important for the anaesthesiologist to gain knowledge about the pulmonary oxygenation.

Gas exchange impairment resulting in hypoxemia

Health care providers experience increasing pressure to reduce costs. Postoperative complications such as hypoxemia may prolong hospital stay, which put additional pressure on the budgets. ALPE essential can help identify patients who are in the risk of devolop Hypoxemia.

Modelling hypoxemia

The principles for pulmonary gas exchange are well-known, but gas exchange is dependent on many varying factors such as insufficient ventilation, shunting of blood, ventilation-perfusion mismatch, abnormal diffusion capacity, cardiac output, and acid-base state of the arterial blood. Full understanding of an oxygenation problem therefore requires complex measurements which have been impractical with today’s technology in daily clinical use.

The ALPE Curve

ALPE essential solution is based on a mathematical model, which from breath-by-breath analysis and measurements of expired end-tidal oxygen (FetO2) and arterial saturation (SpO2) provides health care professionals with two parameters giving reliable pulmonary gas exchange insight.
