Abstract
A wound dressing can include an adhesive dressing with a diaphragm vent that allows the passage of gas out of a patient's body but restricts the flow of gas into the body. A sensor device is positioned so as to be able to sample gas passing through the vent and measure one or more gas characteristics, such as temperature, humidity, and/or pressure. If the data from the sensor device exceeds certain parameters suggestive of a pneumothorax, a processing device can activate an alert system, such as an indicator light, audible alarm, and/or wireless signal, to alert the care provider.
