Humiditiy and temperature sensors for CPAP devices

Continuous positive airway pressure (CPAP) therapy is a mode of respiratory ventilation, which uses a portable machine and pressurized room air to prevent the soft tissue in the back of the throat from collapsing and blocking the upper airway leading to an apnea episode. Because of the applied dry air and pressure, patients often suffer from an inflammation and dryness of the upper airway tract. The impact is more severe when the bedroom temperature is cool, resulting in a low absolute humidity level. Therefore, especially patients requiring heated humidification and with a cooler bedroom temperature benefit from the controlled heated breathing tube humidification technology. Sensirion's humidity and temperature sensors offer the best fit for CPAP devices with controlled heated humidification. They have an outstanding accuracy and operate reliably in high humidity environments. Their miniaturized size enables the placement inside the CPAP device or within the tubing for even better patient comfort.
