  • Head mounted displays may be used according to this invention to present physiological information to a user, e.g., a clinician or supervisory clinician.
  • the HMDs are especially useful for monitoring patients' vital signs and physiological information. For example, it is known that patients suffer abrupt changes in their cardio-pulmonary functions during an intubation procedure. A clinician wears a HMD that receives and presents all the vital signs and physiological information of the patient will be able to closely observe the patient's vital signs without periodically detracting from performing the procedure in order to evaluate the physiology state of the patient. Another example is insertion of a pulmonary catheter. This is a procedure whereby a doctor insert a catheter into and through the heart and on into the pulmonary artery.
  • the HMDs of the present invention are particularly useful in guiding medical procedures. Similar to pulmonary catheter insertion, successful insertion of a bronchoscope also requires continuous knowledge of the location and direction of the tip of the bronchoscope.

  • Head mounted displays of the present invention are useful not only within treatment areas such as operating rooms and emergency rooms as discussed supra, but also outside of treatment areas, particularly in a larger clinical and medical setting where a multitude of patient physiological data are relayed among many clinicians.
  • every clinician may have available a HMD which he or she can wear when needs to access relevant visual information of a given patient whose physiological condition is being monitored.
  • Multiple patients are monitored and operated upon at the same time in various treatment areas in the facility.
  • the physiological information gathered as such may be managed by a centralized information system, which assigns a unique information channel - e.g., a radio frequency - to the physiological data from each patient.
  • the system thus broadcasts in real time such data in multiple channels throughout the hospital facility.
  • a clinician wearing a HMD may selectively tune into a desired channel and receive physiological information regarding a particular patient. Therefore, the use of HMDs in such a system enables practitioners to conveniently gain access to real-time visual information of patient physiological states while on the move. It improves the efficiency and timeliness of the information relay in the medical treatment facility and helps clinicians to evaluate patient conditions and prepare for participating in treatment activities at a distance. Also, users of the system may switch from channel to channel and observe the operations and activities throughout the facility. The system thus provides a means for effective overall monitoring and surveillance, useful especially for those who bear the responsibility to oversee a good number of patients or operations at the same time.
