Other connectivity options in the module include LAN, WiFi, 3G, and WiMax, among others. Depending on the scenario where the medical device is to be used, particular connectivity features can be present. Care has to be taken such that the user is not required to perform confusing put configuring of the device for the various protocols.
Standard formats like DICOM (Digital Imaging and Communication in Medicine) can be used to communicate and ensure criticality and safety of patient data. The data has to be encrypted and transmitted over the channel to prevent potential compromise of medical data, Figure 2.

The authorized personnel (caregivers) would have a secure login to access the medical data from the data centers. The comments provided by the experts are also logged on the server which forms a repository of patient data along with expert’s comments. The servers can run complex algorithms to aid the caregivers in making a diagnosis.
The algorithms can automatically diagnose certain conditions and display this to the patients and care providers. The interface to the healthcare givers should also be intuitive and easy to use. The software must be robust and error free to ensure there are no issues involving erroneous medical data.
Further, the feedback from the caregivers must be communicated to the patients. Use of equipment must provide ample benefits to patients as well as drive the cost of healthcare down. This also increases the extent of quality healthcare by breaking the geographical barriers.
The following parameters which are necessary for a patient monitor are discussed in detail:
- Electrocardiogram (ECG)
- Pulse oximeter
- Glucose monitor
- Respiratory monitor (Spirometer)
- Blood pressure monitor
