To quickly stop a nosebleed, several effective methods can be employed. First, the pinching technique is a commonly used and effective method. This involves pinching the soft part of the nose with the thumb and index finger, applying downward pressure to press the nostrils against the nasal septum—the most common site of bleeding. Maintaining this pressure for 5 to 15 minutes can effectively achieve hemostasis. If available, using a cotton swab soaked in a decongestant like oxymetazoline can further enhance the effect. Insert the cotton swab into the nasal cavity and apply pressure; this method typically results in quicker cessation of bleeding.

In addition to the pinching method, another effective measure is cold compress. Applying a cold, damp towel to the forehead or neck can cause local blood vessels to constrict, thereby aiding in hemostasis. The cold compress should be applied for 15 to 20 minutes, depending on the situation, to achieve the desired effect.

If these methods do not effectively control the bleeding at home, it is advisable to seek medical attention promptly. Healthcare professionals will use a more systematic approach to manage the nosebleed. Initially, they will thoroughly clean the nasal cavity, removing blood clots and secretions. Subsequently, they may use a cotton swab with a local anesthetic and vasoconstrictor, inserting it into the nasal cavity and waiting a few minutes to induce vasoconstriction and stop minor bleeding. For more severe cases, doctors may resort to more complex treatments such as nasal packing, laser therapy, or other surgical interventions to effectively control and stop the bleeding.

In summary, using techniques such as pinching, decongestant treatment, and cold compress can effectively manage a nosebleed, while seeking prompt medical attention is crucial for severe or uncontrollable cases.
