• Become familiar with local capabilities.
• Calling for a medivac
– Ground transport would take too long.
– Spinal cord injuries, amputations, burns, diving emergencies, venomous bites
• Notify your dispatcher first.
![Page 45: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/45.jpg)
Establishing a Landing Zone
• Area should be hard or grassy level surface that measures 100' x 100' (recommended)
• Clear area of loose debris and survey for overhead or tall hazards.
• Mark landing site with weighted cones or headlights.
![Page 46: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/46.jpg)
Safety Precautions
• Do nothing near the helicopter and only go to where the crew or pilot directs you.
• Keep a safe distance away from the aircraft.• Stay away from the tail rotor.• Never approach the helicopter from the rear.
![Page 47: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/47.jpg)
Special Considerations
• Nighttime landings– Considerably more dangerous than daytime
operations• Landing on uneven ground
– Main rotor blade will be closer to the ground on uphill side.
• Hazardous materials incidents– Land zone should be upwind and uphill.
![Page 48: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/48.jpg)
Landing on Uneven Ground
![Page 49: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/49.jpg)
Review1. Upon arrival at a scene where hazardous materials
are involved, you should park the ambulance:
A. upwind from the scene.B. with the warning lights off. C. downhill from the scene. D. at least 50’ from the scene.
![Page 50: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/50.jpg)
ReviewAnswer: A
Rationale: At the scene of a hazardous materials incident, the ambulance should be parked uphill and upwind from the scene. Other locations may expose the ambulance to any escaping hazardous material. Be prepared to quickly move the ambulance if the wind shifts in your direction.

ReviewAnswer: D
Rationale: The “en route to the scene” phase of a call is the most dangerous. Regardless of the nature of the call that you are responding to, wearing seat belts and shoulder harnesses is the most important safety precaution that you and your partner must take. Furthermore, you must drive defensively and remain aware of the traffic around you.
![Page 63: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/63.jpg)
Review5. While en route to a call for a major motor-vehicle crash, the
MOST important safety precaution(s) that you and your partner can take is/are:
A. adhering to body substance isolation precautions. Rationale: This takes place once the providers arrive at the scene.B. ensuring that the fire department arrives before you. Rationale: it is important to know if the fire department is
responding, but this is not the most important safety precaution.
C. using lights and siren and being aware of other drivers.Rationale: The use of lights and sirens adds to the risk potential,
but the use of safety devices is the most important precaution that you can take.
D. wearing seat belts and shoulder harnesses at all times. Rationale: Correct answer

![Page 65: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/65.jpg)
ReviewAnswer: C
Rationale: The dimensions for a helicopter landing zone (LZ) should be, at a minimum, 100' × 100' on a hard or grassy surface that is level. The LZ should be clear of loose debris and power lines.
![Page 66: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/66.jpg)
Review6. The minimum recommended dimensions for a helicopter landing
zone are:
A. 50’ × 50’Rationale: This is below the minimum recommended dimensions.B. 75’ × 75’Rationale: This is below the minimum recommended dimensions. C. 100’ × 100’Rationale: Correct answerD. 150’ × 150’Rationale: This is well above the minimum recommendations, but
this may not be a practical size in many emergency operations.

Review7. At what speed will the ambulance begin to
hydroplane when there is water present on the roadway?
A. 25 mphB. 30 mphC. 40 mphD. 50 mph
![Page 68: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/68.jpg)
ReviewAnswer: B
Rationale: At speeds of 30 mph or greater, the tires can be lifted off the pavement as the water “piles up” under the tires. This takes the control out of the driver's hands. If hydroplaning occurs, you should gradually slow down instead of jamming on the brakes to avoid losing control of the vehicle.

Review7. At what speed will the ambulance begin to hydroplane when
there is water present on the roadway?
A. 25 mphRationale: This is below the speed where the risk of hydroplaning
exists.B. 30 mphRationale: Correct answerC. 40 mphRationale: This exceeds the speed at which hydroplaning can
occur.D. 50 mphRationale: This exceeds the speed at which hydroplaning can
occur.

ReviewAnswer: D
Rationale: Think of a jump kit as the “5 minute kit,” containing anything you might need in the first 5 minutes with the patient. It is during this 5 minute period that you will find and manage immediate life threats.
![Page 75: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/75.jpg)
Review9. The primary purpose of a “jump kit” is to:A. ensure that you have immediate access to the AED.Rationale: A “jump kit” should have the basic equipment to treat
immediate life threats. BLS care can be initiated until an AED arrives.
B. have all of the equipment available that you will use in the entire call.
Rationale: You only need that equipment to manage immediate life threats during the first five minutes. Afterwards, additional equipment can be brought to the scene.
C. have easy access to manage patients with severe uncontrolled bleeding.
Rationale: A “jump kit” should have the basic equipment to manage all immediate life threats — including airway and breathing.
D. have all of the equipment available that will be used in the first five minutes.
Rationale: Correct answer

Review10. Which of the following statements about helicopters
is true?
A. It is possible that the main rotor blade will dip to within 4' of the ground
B. A helicopter is considered “hot” when it is on the ground and the rotors are still
C. If the helicopter must land on a grade, you should approach it from the uphill side
D. If you must go from one side of the helicopter to the other, the best way is to duck under the body.
![Page 77: 35: Ambulance Operations. Cognitive Objectives (1 of 4) 7-1.1Discuss the medical and nonmedical equipment needed to respond to a call. 7-1.2List the phases](https://reader036.vdocument.in/reader036/viewer/2022062713/56649ce25503460f949adb17/html5/thumbnails/77.jpg)
ReviewAnswer: A
Rationale: Because the main rotor blade of a helicopter is flexible, it can dip as low as 4' from the ground. Use extreme caution when approaching a helicopter with the rotors on. If the helicopter must land on a grade, approach it from the downhill side. When moving from one side of the helicopter to the other, move around the front of the aircraft—not under it and certainly not behind it!
