**7.1 Monitoring of hemodynamic and vital constants**

Several systems enable the delivery of mobile health monitoring services for outpatients and/or those outside of healthcare settings. Examples of these systems include the pulse oximeter of Masimo.com, the adhesive patch of Isansys.com, the electronic tattoo of mc10inc.com, or necklace of Tosense.com.

Several parameters can be analyzed such as: heart rate, heart rate variability, respiratory rate, skin temperature, stroke volume and cardiac output.

The information is transmitted to the Smartphone so that health professionals and/or patients can be informed quickly in case of clinical deterioration [61].

## **7.2 Remote monitoring of surgical wounds**

Postoperatively, the Smartphone can be used as a tool for the monitoring and surveillance of postoperative infection sites. These infections can occur up to 30 days postoperatively. Monitoring can be done through sharing images of the surgical site and remote video conferencing [62, 63].
