How can real-time telemetry enhance patient care during air evacuation?

Real-time telemetry plays a crucial role in enhancing patient care during air evacuation by transmitting essential health data to hospitals. This technology allows for continuous monitoring of a patient's vital signs and relevant health information while they are en route to a medical facility. By sending this data in real time, the receiving hospital can prepare for the patient's arrival more effectively, ensuring that appropriate medical personnel and resources are ready to meet the needs of the patient immediately upon landing. This level of preparedness can make a significant difference in emergency situations, where time is of the essence.

The other choices do not align as directly with the advantages that real-time telemetry provides. For instance, while telemetry doesn't reduce the need for monitoring, it actually enhances monitoring efficiency. Additionally, while determining flight routes is important for logistics, it does not directly enhance patient care as telemetric data would. Lastly, limiting medical personnel involvement contradicts the fundamental purpose of evacuation, which is to provide the necessary care and support to patients during transport.
