What technique should a litter attendant use to ensure a patient's safety during the operation?

Using a face shield and keeping the patient's extremities in the litter is crucial for ensuring the patient's safety during an operation. This technique helps protect the patient's head and face from potential injuries or environmental hazards, particularly in dynamic or rough environments typical of rescue operations.

Additionally, keeping the patient's extremities within the boundaries of the litter minimizes the risk of them being snagged on obstacles or accidentally injured during the rescue process. This is vital as it prevents potential additional injuries that could complicate the patient's condition.

The use of restraints, including straps to secure the patient inside the litter, further enhances safety by preventing any movement that could lead to further injury during transport. This comprehensive approach acknowledges the importance of both head protection and secure positioning within the litter, contributing to overall patient safety during a critical rescue operation.
