Landing Zone Preparation &
CommunicationsWhy is this so important?

Undesignated / Spontaneous LZs
• High risk –espc at night
• Obstacles on approach Wires Cell Towers
• Ground hazards – signs, poles debris
• LZ security – people vehicles
• How well was it scouted out –we are 100% dependent on your eyes
![Page 4: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/4.jpg)
Alternate LZs.You don’t have to land the helicopter
exactly at the accident scene
That’s why God put wheels on the ambulance
![Page 5: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/5.jpg)
Designated LZs
![Page 6: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/6.jpg)
Communication
• MF dispatch 608-263-3258
• Your county 911 dispatch
• Cell contact on scene
![Page 7: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/7.jpg)
Initial Info
• Location – street and cross street
• Relationship to city, well known landmark
• Contact agency
• Cell contact on scene
• Contact frequency – Typically Marc 2
• Incident type and basic patient info
• Do you need more than 1 helicopter?
![Page 8: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/8.jpg)
Radio contact
• MARC 2
• 5-10 minutes out
• Use vehicle radios – handheld have limited range
• Our #1 interest – LZ information
• VERY brief patient update
![Page 9: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/9.jpg)
What to do if no radio contact ?
![Page 10: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/10.jpg)
Common LZ Problems
• Personnel “marking” the LZ
• Personnel approaching aircraft before blades stop turning
• LZ security once helicopter lands
• LZ has to be secured 5 minutes prior to landing until 2 minutes after takeoff
• No vehicle, regardless of height within 50 ft of aircraft. Especially ambulances

Im not afraid of heights
Im afraid of widths

Wisconsin EMS Rule 11a
If it is Saturday night and you respond to an accident scene after
10pm and do not find a drunk-
Keep looking because you are missing a patient

The concept of “Holding the C-Spine”
![Page 27: Best of Med Flight. Landing Zone Preparation & Communications Why is this so important?](https://reader036.fdocuments.in/reader036/viewer/2022062409/56649ce25503460f949adb87/html5/thumbnails/27.jpg)

Radically changes treatment
• Not just a drowning
• It’s a drowning caused by syncope caused by cardiac arrhythmia
• Drowning similar to geriatric falls- What caused it? Primary vs secondary
