CIPOLLETTI, M. et al. A wireless sensor network for endotracheal tube cuff pressure monitoring. Lat. Am. appl. res. [online]. 2009, vol.39, n.1, pp.27-32. ISSN 0327-0793.

Endotracheal tubes (ETT) are kept in position using inflatable cuffs. The pressure of the cuff needs to be higher than a minimum value to hold the ETT in place. However, pressures exceeding 20mmHg produce damage of different degrees on the trachea. This paper shows an experimental network of wireless and low power nodes for monitoring the pressure of ETT cuffs (ETTC). All nodes communicate wirelessly through an RF link with a central station that displays values on a PC and generates alarms if values are beyond the limits prescribed by the physician. The system was tested to monitor the condition of several patient ETTC in a coronary intensive care unit of the "Hospital Privado del Sur", in Bahía Blanca, Argentina.
