Abstract

Systems and methods for virtual reality (VR) training of medical events are described herein. In one aspect, a method for generating a VR medical training environment can include displaying a medical event through a VR headset, receiving, from a user of the VR headset, a set of verbal responses corresponding to the user reacting to the medical event, determining a timestamp for at least one verbal response received from the user, determining a medical event score for the user based on the set of verbal responses and the timestamp, and displaying a summary of the medical event score via the VR headset or a display screen.

First claim

The invention claimed is:

1. A method for generating a virtual reality (VR) medical training environment, the method comprising:
displaying a virtual reality medical event through a VR headset;
receiving, from a user of the VR headset, a set of verbal responses corresponding to the user reacting to the virtual reality medical event;
determining a timestamp for at least one verbal response received from the user;
determining a medical event score for the user based on the set of verbal responses and the timestamp, the medical event score being based on a comparison of the set of verbal responses to a set of predetermined medical guidelines; and

displaying a summary of the medical event score via the VR headset or a display screen.

2. The method of claim 1 , further comprising:
generating a virtual action implemented by a virtual character in the VR training environment based on at least one response received from the user.

3. The method of claim 1 , wherein the medical event further comprises a cardiac emergency event.

4. The method of claim 1 , further comprising:
converting at least one verbal response received from the user into text via a text-to-speech-application.

5. The method of claim 1 , wherein the set of medical guidelines comprises American Heart Association cardiac arrest guidelines.

6. The method of claim 1 , further comprising:
updating a condition of a virtual patient based on at least one received verbal response.

7. The method of claim 1 , wherein the VR medical training environment further comprises an in hospital cardiac arrest (IHCA) setting or an out of hospital cardiac arrest (OHCS) setting.

8. A system for generating a virtual reality (VR) medical training environment, the system comprising:
a VR headset adapted or configured to:
display a virtual reality cardiac emergency event;
receive, from a user, a set of verbal responses corresponding to the user reacting to the virtual reality cardiac emergency event;
determine a timestamp for at least one verbal response;
determine a medical event score for the user based on the set of verbal responses and the timestamp, the medical event score being based on a comparison of the set of verbal responses to a set of predetermined medical guidelines; and
display a summary of the medical event score.

9. The system of claim 8 , wherein the VR headset is further adapted or configured to:
generate a virtual action implemented by a virtual character in the VR training environment based on at least one response received from the user.

10. The system of claim 8 , wherein the VR headset is further adapted or configured to:
convert at least one verbal response received from the user into text via a text-to-speech-application.

11. The system of claim 8 , wherein the set of medical guidelines further comprises American Heart Association cardiac arrest guidelines.

12. The system of claim 8 , wherein the VR headset is further adapted or configured to:
update a condition of a virtual patient based on at least one received verbal response.

13. The system of claim 8 , wherein the VR medical training environment further comprises an in hospital cardiac arrest (IHCA) setting or an out of hospital cardiac arrest (OHCS) setting.
