Tracheotomy
The emergency procedure is called a tracheotomy.
It is called Airway obstruction / Tracheal obstruction
Establish the patients level of responsiveness. Open the Infants airway using the head-tilt chin lift maneuver. Check for breathing by looking down the throat, listening and feeling for any obstruction. Perform infant rescue breathing. Abdominal Thrusts called the Heimlich Maneuver.
An obstruction in a person's airway can be caused by food or small objects getting lodged in the throat, swelling in the throat from an allergic reaction or infection, or physical trauma to the neck. This blockage can restrict the person's ability to breathe and lead to serious consequences if not treated promptly.
Stridor refers to a strained, high-pitched noisy breathing sound that occurs due to partial obstruction in the larynx or bronchus. It is typically heard during inspiration and can indicate various underlying respiratory issues, requiring medical evaluation and treatment.
I believe the procedure you are referring to is called tracheotomy - it involves making an opening below the blockage within the airway if the blockage cannot be easily or quickly removed, and allowing the afflicted to breathe through that opening instead, until emergency services arrive.This procedure, if in an emergency, can be performed at home, provided that care is taken not to harm the patient more as much as possible (ie. by not severing any arteries or nerves), and it would involve, for example, putting a hollowed-out pen below the person's throat, in order to secure an open passage of air to the person's lungs.Do keep in mind that emergency procedures should only be performed if there is no other choice, since a layperson can easily do more harm than good, and only in the face of immediate risk of loss of life. When in doubt, always try the less invasive and less risky procedures first, and then try to do the absolute minimum needed to keep the person alive until qualified assistance arrives.
Number 1 is make sure the power is off before entering the scene. Make sure 911 or emergency number has been called. Perform ABCs on the patient when it is safe to enter the scene. If the victim is breathing and has a pulse, keep airway open and monitor patient. Bleeding may have to be controlled as well.
