Question 24 LB01 - Lifeboat Operator

The Correct Answer is B **Why option B ("The rescue sling") is correct:** The rescue sling (or strop) should be avoided when hoisting a patient who is hypothermic because it forces the patient into a near-vertical posture. This vertical positioning can trigger a phenomenon known as "circum-rescue collapse" or "post-rescue collapse." When a severely hypothermic person is suddenly moved to the vertical position, the cold-induced peripheral vasoconstriction (narrowing of blood vessels in the extremities) is suddenly overcome, causing cold, acidic blood from the limbs to rush back to the core. This shift can lead to a sudden and severe drop in central blood pressure (orthostatic hypotension), ventricular fibrillation, or cardiac arrest. Furthermore, the sling provides no thermal insulation or stabilization, both of which are critical for managing a hypothermic patient. **Why the other options are incorrect:** * **A) The rescue litter (or 'stretcher')** is the preferred device for hoisting a hypothermic patient. It allows the patient to remain in a horizontal, supine position, minimizing the risk of circum-rescue collapse by maintaining even blood pressure distribution. It also provides the best opportunity for immobilization, thermal management (e.g., wrapping in blankets), and in-transit monitoring. * **C) The rescue net** (or "Talon" net) is designed to enclose the patient securely while keeping them horizontal or near-horizontal. While less ideal than a rigid litter for access to the patient, it is far superior to a sling because it prevents the vertical positioning that triggers circum-rescue collapse. * **D) The rescue basket** is also an acceptable device for hoisting a hypothermic patient, as it keeps the patient horizontal or semi-recumbent and provides a degree of protection and support. Like the litter and net, it avoids the dangerous vertical suspension caused by the sling.
