What should be done if a crew member notices bleeding on a passenger?

Using compresses from the first aid kit is the appropriate response when a crew member notices bleeding on a passenger. Immediate application of compresses can help control the bleeding by applying direct pressure to the wound, which is crucial in preventing further blood loss and stabilizing the passenger's condition until professional medical assistance can be obtained.

Applying a tourniquet is typically reserved for severe, life-threatening bleeding from a limb where direct pressure does not suffice. If the bleeding is serious enough to require a tourniquet, it would be indicated only after proper evaluation of the situation.

Notifying the pilot is important as part of addressing the situation, but simply informing them without taking immediate action to control the bleeding does not provide the necessary first aid to the affected passenger.

Waiting for further instructions is not advisable in an emergency scenario like this, where immediate action can make a significant difference in the outcome for the injured passenger. Taking swift action to control the bleeding is essential.
