As a medical professional with extensive experience in emergency care and trauma management, I have often been asked about the proper application and tightness of a tourniquet. The use of a tourniquet is a critical procedure in situations where there is severe bleeding that cannot be controlled by direct pressure. It's a life-saving technique that requires careful consideration and precise application to be effective.
When applying a tourniquet, there are several key points to consider:
1. Width: The tourniquet should be at least 4cm wide. This width is important to prevent localized damage to nerves and tissues. A narrower tourniquet can cause more harm than good by concentrating pressure on a smaller area.
2. Tightness: The tourniquet must be applied with sufficient tightness to stop the bleeding. The goal is to occlude arterial blood flow to the limb, which requires a significant amount of pressure. If the tourniquet is not tight enough, it will not be effective in stopping the bleeding and may even exacerbate blood loss by causing the blood to pool and exert pressure on the tourniquet from below.
3. Location: The tourniquet should be placed as close to the injury site as possible without compromising the function of the limb. This helps to minimize the amount of limb that is deprived of blood flow.
4. Number: In some cases, it may be necessary to apply more than one tourniquet to completely stop the bleeding. This is particularly true in cases of severe trauma where a single tourniquet may not provide enough pressure to stop arterial bleeding.
5. Time: It is crucial to monitor the time that a tourniquet is in place. Prolonged use of a tourniquet can lead to tissue death and other complications. The longer a tourniquet is on, the greater the risk of these complications.
6. Marking: Always mark the time the tourniquet was applied on the tourniquet itself or on the patient's skin near the tourniquet. This is to ensure that medical personnel are aware of how long the tourniquet has been in place and can make informed decisions about its removal.
7.
Pain Management: Applying a tourniquet can be extremely painful. It is important to manage the patient's pain as much as possible, both during the application of the tourniquet and while it is in place.
8.
Training: Proper training is essential for the effective use of a tourniquet. Medical professionals and first responders should be well-versed in the techniques and protocols for tourniquet application.
In conclusion, the tightness of a tourniquet is a delicate balance between providing enough pressure to stop bleeding and not causing additional harm. It should be tight enough to stop arterial flow but not so tight as to cause unnecessary damage or pain. The application of a tourniquet is a serious procedure that should only be performed by trained individuals in emergency situations.

A tourniquet should be at least 4cm wide to prevent localised damage to nerves tissues. A tourniquet must be put on sufficiently tight to stop the bleeding. If it is not tight enough it can actually end up increasing blood loss. It may be necessary to apply more than one tourniquet to completely stop bleeding.Jan 6, 2017
