Tree Stand Falls, Backcountry Penetrating Trauma, and Remote Evacuation¶

Across North America and Europe, elevated tree stand falls are the single leading cause of hunting-related hospitalizations and deaths, far surpassing firearm and archery discharges combined. Falling 4.5 to 7.5 meters (15 to 25 feet) from a climbing stand, hang-on platform, or ladder stand causes high-energy vertical deceleration trauma to the cervical spine, thoracic aorta, pelvis, and calcanei, while hanging motionless in a full-body safety harness without a suspension relief strap triggers fatal orthostatic suspension trauma in as little as 15 to 30 minutes.

Also, when an accidental firearm discharge or razor-sharp broadhead arrow impalement occurs kilometers from the nearest paved road, survival depends entirely on immediate self-aid or buddy-aid during the first 3 to 10 minutes. This guide details the exact rescue protocols for harness suspension trauma, the MARCH tactical backcountry trauma algorithm (tourniquets, junctional wound packing, vented chest seals, and broadhead arrow stabilization), GPS coordinate extraction, and helicopter landing zone (LZ) preparation.

现在就这样做¶

1. Make sure scene safety and unload all firearms or crossbows first: Before touching an injured hunter or climbing down to help, engage the safety, point the muzzle in a safe direction, completely unload the chamber and magazine of every firearm or uncock any crossbow at the scene and place all weapons and open broadhead quivers at least 3 meters (10 feet) away so a panicked or spasming patient cannot trigger a second discharge.
2. If hanging in a tree stand harness, deploy your suspension relief loop immediately: Pull the suspension relief strap (foot loop) from your harness pocket, clip or loop it at knee height, step into the loop, and stand up or pump your calf and thigh muscles every 5 to 10 seconds to drive venous blood back to your heart while you either climb back onto the platform, cut yourself down onto a ladder rung, or blow your rescue whistle and call for help.
3. Stop massive arterial bleeding within 60 seconds (M in MARCH):
4. Limb gunshot or broadhead wound (thigh, calf, arm): Apply a CoTCCC windlass tourniquet (CAT or SOFTT-W) 5 to 8 centimeters (2 to 3 inches) above the wound (or "high and tight" over hunting clothes if the exact wound site is hidden), crank the windlass until all bright red bleeding stops, and write the time on the strap; see severe bleeding and tourniquets。
5. Neck, armpit, or groin (junctional) wound: Immediately pack the wound cavity tightly with z-fold hemostatic gauze (or clean cotton cloth) pushed straight down onto the bleeding artery with your fingers, then hold firm two-handed direct pressure for 3 to 10 minutes.
6. Stabilize impaled broadhead arrows or branches in place: Never remove an impaled arrow, bolt, or tree branch. If an arrow shaft protruding from a thigh, arm, or chest is too long to evacuate safely without snagging brush and levering the razor blades inside the body, carefully stabilize the shaft with two hands and use heavy wire cutters or a multi-tool saw to shorten the carbon/aluminum shaft 10 to 15 centimeters (4 to 6 inches) outside the skin without vibrating the broadhead, then tape bulky foam pads or rolled socks around the base. See impalement and embedded foreign object stabilization。
7. Seal open chest wounds immediately (A and R in MARCH): If a gunshot, arrow, or broken rib from a tree stand fall creates an open chest wound (or both an entry and exit wound on the torso), wipe away blood and apply a vented chest seal (or a 3-sided taped plastic square) over both the entry and exit wounds on exhalation to prevent a fatal tension pneumothorax. See tension pneumothorax and sucking chest wound first aid。
8. Protect the spine, prevent hypothermia, and transmit exact GPS coordinates: Keep any hunter who fell from a tree stand flat and still on an insulated foam pad wrapped in dry jackets and a mylar blanket. Call your local emergency number (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom; see all 紧急号码) or trigger your satellite SOS beacon, and read your exact decimal-degree GPS coordinates from your phone compass/mapping app (OnX Hunt, Garmin, Apple/Google Maps) to dispatch.

Mechanism Comparison Matrix: Tree Stand Falls vs. Ballistic vs. Broadhead Trauma¶

Surviving a Tree Stand Fall: Harness Suspension Trauma & Ground Impact¶

1. The Physiology of Harness Suspension Trauma (Orthostatic Intolerance)¶

Modern hunting standards require wearing a Full-Body Fall Arrest System (FAS / TMA-certified harness) tethered to the tree from the moment your feet leave the ground via a lineman's belt or safety lifeline. However, catching your fall in a harness is only half the battle: - Why the "Venous Muscle Pump" Fails in Mid-Air: Normally, when you stand on the ground, contractions of your calf and thigh muscles squeeze deep veins and push deoxygenated blood upward through one-way valves back to your right atrium. When you hang suspended in mid-air after a tree stand collapses, gravity pulls blood down into your legs while the tight webbing of the harness leg straps compresses the femoral veins in your groin blocking venous return to the heart. - The 15-Minute Countdown: Within 5 to 15 minutes of hanging motionless, up to 60 percent of your circulating blood volume becomes trapped in your lower extremities. Cardiac output plummets, blood pressure crashes, and the brain triggers a sudden paradoxical vasovagal reflex (the Bezold-Jarisch reflex) that slows the heart rate, causing sudden loss of consciousness. Once unconscious in a vertical harness, the hunter's head slumps forward (compromising the airway) and fatal hypoxic cardiac arrest follows within 15 to 30 minutes.

2. Step-by-Step Self-Rescue When Hanging in a Tree Stand Harness¶

Every hunter must carry three items in an exterior chest or side pocket that remains accessible while hanging under tension (never inside a zipped pants pocket pinched beneath a tight leg strap): a Suspension Relief Strap a heavy-duty folding knife or strap cutter and a pealess whistle / cell phone / satellite SOS beacon. 1. Brace and Pump Immediately: The instant your fall stops, push your boots against the tree trunk and flex your leg muscles rhythmically so blood cannot pool. 2. Deploy the Suspension Relief Strap: Pull the coiled relief strap from your harness, attach it to the harness loop at waist level, adjust the foot stirrup so it hangs slightly above your ankles, hook both boots into the stirrup, and stand straight up in the loop. Standing in the foot loop transfers your body weight off your groin straps onto the soles of your feet, restores 100 percent of femoral venous blood flow, and reacts your leg muscle pumps, buying you hours of safe survival time. 3. Improvised Relief Loop (If You Lost Your Relief Strap): If you do not have a relief strap, take your lineman's climbing belt, deer drag rope, or binocular harness strap tie or loop it around the tree trunk or into your harness tether at knee height, and step one foot into the loop to take pressure off your groin straps. 4. Recover onto the Stand or Descend: While standing in the relief loop, hug the tree trunk to unweight your back tether, slide the tree tether strap downward 30 centimeters (12 inches) at a time to inch down to a climbing stick or ladder rung, or swing back onto the platform. 5. Post-Rescue Positioning After Prolonged Suspension: Once a hunter who has been hanging in a harness for more than 15 minutes is lowered to the ground: - If unconscious or in cardiac arrest: Lay them flat (supine) immediately, open the airway, and start CPR。 - If conscious and alert: Modern Wilderness Medical Society (WMS) and occupational rescue guidelines advise transitioning the conscious patient carefully, monitoring their airway and important signs closely, loosening all harness straps immediately, and keeping them warm while evacuating to an emergency department to screen for crush-like rhabdomyolysis and hyperkalemia (muscle breakdown toxins and potassium released from ischemic legs).

The Backcountry MARCH Algorithm for Gunshot and Broadhead Trauma¶

When a high-powered hunting rifle, shotgun, muzzleloader, or compound bow/crossbow injures a hunter in remote timber, follow the tactical MARCH sequence (Massive hemorrhage, Airway, Respiration, Circulation, Hypothermia/Head):

1. M, Massive Hemorrhage (First 60 Seconds)¶

• 四肢伤口的止血带放置：如果血液从裤腿流下来，不要浪费宝贵的时间剪掉三层绝缘狩猎围兜来查看喷血的股动脉。将 CoTCCC 卷扬机止血带（CAT 或 SOFTT-W）“高且紧”放置在光滑衣服上的大腿或上臂的最顶部（确保束带下方的口袋中没有手机、刀或弹药盒），尽可能拉紧自粘束带，然后扭转卷扬杆，直至鲜红色出血完全停止。一旦场景稳定，暴露伤口，如果需要，将第二条止血带直接放在皮肤伤口上方 5 至 8 厘米（2 至 3 英寸）处，然后松开高而紧的带子。
• 简易野外狩猎止血带：如果您没有携带商用止血带，请使用 5 厘米（2 英寸）宽的帆布步枪吊带、双眼带或折叠的火橙色背心带包裹在伤口上方，并用金属螺栓、清洁杆部分或粗壮的硬木棍拧紧作为卷扬机。如果下面没有宽织物带，切勿单独使用细伞绳或鞋带，因为细绳会割伤皮肤，而不会阻塞深部股动脉。
• 腹股沟、臀部、腋窝或颈部伤口的伤口包扎：如果子弹或阔头枪割伤了腹股沟折痕（腹股沟交界处）、腋窝或颈根部的血管，请将手指包裹在止血纱布（QuikClot 战斗纱布或 Celox） 或干净的棉质 T 恤条中，并 将其直接一寸一寸紧紧地塞到创腔底部的出血血管上直至包扎略高于皮肤水平，然后用双手俯身3至5分钟（止血）或10分钟（普通纱布）。

2. 特别协议：宽头箭和弩箭穿刺¶

现代狩猎箭和弩箭的尖端带有固定刀片或机械（可扩展）宽头，设计用于通过 2、3 或 4 个手术级剃须刀刀片最大限度地减少出血，跨度2.5 至 6 厘米（1 至 2.5 英寸），切割直径： 1. 为什么拔出宽头会致命：在体内，碳箭杆和刀片压在静脉和动脉的切片壁上（内部填塞）。此外，机械阔头具有后向带刺刀片，向后拉动时会像雨伞一样打开，而固定刀片阔头会随着箭头的柔性脊柱弯曲而旋转。在树林里拔出一支箭，就会将邻近完整的神经、肌腱和大动脉切开。 2. 如何在野外稳定被刺穿的箭： - 用创伤剪刀或小刀剪掉箭杆周围的夹克和衬衫，这样衣服就不会拉扯箭杆。 - 如果箭头进入部位周围渗出血液，请将无菌纱布垫牢牢地压在皮肤上沿着轴的底部，不要倾斜或摆动箭头。 - 使用卷起的袜子、备用羊毛帽、泡沫垫条或大纱布卷，在箭头周围搭建一个高度为 8 至 10 厘米（3 至 4 英寸）的小木屋或甜甜圈垫，并将衬垫牢固地粘在身体上，这样箭头在垃圾运输过程中就不会枢转。 3. 何时以及如何缩短箭杆：如果 75 厘米（30 英寸）的箭杆从猎人的大腿或胸部浓密的灌木丛中伸出，则每根树枝都会撞击带羽毛的羽毛末端，并将剃刀阔头刺入患者的器官内。 - 让合作伙伴用双手将箭头轴固定在靠近皮肤入口点的虎钳状手柄中（或用锁紧钳将其紧紧夹住），以吸收 100% 的振动。 - 使用重型钢丝钳、旋转切管机或细齿多功能工具锯在皮肤上方 10 至 15 厘米（4 至 6 英寸）处切割空心碳或铝轴**。将一块胶带缠绕在粗糙的碳纤维末端，这样锋利的碳碎片就不会伤害救援人员。

3. A & R、气道和呼吸（入口和出口伤口规则）¶

高速狩猎步枪子弹（.270、.308、.30-06、6.5 Creedmoor）几乎总是完全穿过人体躯干，在正面形成一个小而整齐的入口伤口，在背面或侧面形成一个更大、参差不齐的出口伤口。 - 检查“方框”（颈部到肚脐、正面、侧面和背面）：将戴手套的双手扫过猎人背心内的整个正面、腋窝和背面。 - 应用通风胸部密封：锁骨和肚脐（前面或后面）之间的任何穿透性伤口都可能导致肺部塌陷（气胸）。擦去皮肤上的血液和汗水，并在呼气结束时在入口伤口上应用通风的商业胸封，并在出口伤口上应用第二个胸封。如果临时使用重型塑料密封袋或零食包装纸，请用胶带粘住三个侧面，并将底角不粘上胶带，这样滞留的空气就可以从胸部喷出，而不会被吸回。 - 注意进行性张力性气胸：如果胸部伤口封闭的患者逐渐呼吸急促、嘴唇发蓝、腕部桡动脉脉搏消失、极度焦虑或颈部静脉扩张，通过揭开一角 3 到 5 秒来打嗝胸部密封，让滞留的高压空气从胸膜腔中发出嘶嘶声，然后将密封恢复平滑。

4. C & H、循环、骨盆束缚和低体温预防¶

• 阻止死亡的创伤三联征：十一月寒冷的森林中，一名流血的创伤患者迅速失去体温。一旦核心温度降至**35摄氏度（95华氏度）**以下，血小板和凝血因子就会停止工作（低温凝血病），导致伤口再次开始无法控制地流血。
• 立即隔热罩：即使空气感觉温和，也要立即将闭孔泡沫座垫、背包或厚厚的松树枝床滑到受伤的猎人下面，使其远离寒冷的泥土或雪。将它们包裹在干燥的羽绒层中，用火橙色的外壳包裹，将化学暖手器放置在腋窝和胸部（覆盖在薄衬衫层上，切勿暴露在裸露的皮肤上），以及防风的聚酯薄膜太空毯。

协调偏远偏远地区疏散和直升机着陆区 (LZ)¶

当在树林深处拨打紧急调度 (911 / 112 / 999) 或通过卫星 SOS 设备（Garmin inReach、Zoleo、SPOT 或 iPhone/Android 卫星 SOS）发送消息时：

1. 前 30 秒内传输的准确信息¶

1. 以十进制度或度分秒为单位的精确 GPS 坐标：打开您的狩猎地图应用程序（OnX Hunt、BaseMap、Gaia GPS、Garmin Explore 或 Apple/Google Compass）并读取准确的纬度和经度（例如， 45.67892, -111.04567)，加上最近的伐木道路、步道入口或溪流排水系统的名称。
2. 采用的机制和关键干预措施：明确说明*“早上 07:40 使用卷扬机止血带狩猎右大腿枪伤”或“6 米（20 英尺）树倒下，背部瘫痪。”* 特别要求 空中医疗直升机派遣 (医疗后送) 和 偏远地区搜救 (SAR) 垃圾小组 可以缩短农村响应时间 30 至 60 分钟，因为农村地区的响应时间缩短了 30 至 60 分钟救护人员无法独自运送一名 100 公斤重的猎人穿过树林 3 公里。
3. 用火焰橙色标记每个小径交汇处：如果有第二个同伴，请在主要伐木道路大门和通往患者的小径的每个岔路口悬挂火焰橙色狩猎背心、测量员的标记胶带或荧光棒，以便即将到来的护林员和护理人员可以直接跑到现场而不会迷路。

2. 如何在树林中准备紧急直升机着陆区（LZ）¶

如果医疗或救援直升机飞向森林空地、草地或宽阔的伐木道路： - 最小清理尺寸： - 白天着陆区：对于大型直升机来说，至少25 x 25 米（75 x 75 英尺），理想情况下30 x 30 米（100 x 100 英尺），完全没有树木、高于 45 厘米（18 英寸）的树桩和架空电线。 - 夜间着陆区：至少45 x 45 米（150 x 150 英尺）。 - 地面坡度：着陆点必须坚固（不是深沼泽泥或薄湖冰），坡度小于 8 至 10 度（坡度超过 10 度会导致主旋翼桨叶撞击上坡山坡）。 - 保护所有松散的装备免受 130 公里/小时（80 英里/小时）的旋翼清洗：在直升机接近之前，收起或压下所有松散的聚酯薄膜太空毯、泡沫垫、帽子和空装备袋。松散的聚酯薄膜毯被吸进直升机尾桨将导致灾难性的坠机。将患者的低温包裹紧紧系在腰带或胶带上，并保护患者的眼睛免受飞扬的松针和灰尘的侵害。 - 指示风向，切勿在夜间使用白色闪光灯：在空地的上风边缘，背对风站立（或将一条明亮的旗形胶带绑在杆子上作为风向袋），因为直升机总是在风中着陆和起飞。晚上，使用彩色化学荧光棒、红色/琥珀色车辆危险物或手电筒向下指向空地中心的地面； 切勿在驾驶舱内照射明亮的白色头灯或狩猎聚光灯，这会损坏飞行员的夜视镜 (NVG)。

每个猎人的狩猎前安全检查表¶

• 每次狩猎时都佩戴经过 TMA 认证的全身防坠落安全带：在攀登第一个梯级之前，将垂直安全救生索（带有 Prusik 结）或架线工的攀爬带夹在树的底部，这样您从上到下 100% 连接。
• 验证您的避震带是否已连接且可用：在开放日之前，坐在距离地面 15 厘米（6 英寸）的安全带上的后院树上，练习展开脚环并在全身重量下​​踩入其中。
• 切勿携带已装弹的枪支或未遮盖的阔头枪攀爬：始终在树的底部卸下枪支或十字弓，将其连接到牵引绳（枪口朝下远离您），只有在您被绑在平台上后才能将其拉起。将所有宽头箭头装在一个刚性的、带帽的箭袋中，该箭袋完全包裹住刀片。
• 在腰带或胸部装备上携带个人急救箱 (IFAK)：在身上携带正品 CoTCCC 卷扬机止血带（CAT 或 SOFTT-W） z 形折叠止血纱布、紧急压力敷料、两包通风胸部密封件、太空毯和响亮的无声哨子，不要留在卡车内。
• 在您的地图应用程序中留下书面的狩猎计划图钉：在 OnX Hunt 或 Google 地图中放置您确切的树站位置的数字路径点图钉，并在黎明前将其连同您的预计入住时间一起通过短信发送给家庭成员。
