Heimlich maneuver, also known as Abdominal thrusts or Heimlich manoeuvre, is a first-aid procedure used to treat upper-airway obstructions (or choking) by foreign objects. American doctor Henry Heimlich is often credited for its discovery.
The jaw-thrust maneuver is an effective airway technique, particularly in the patient in whom cervical spine injury is a concern. It is easiest when the patient is positioned supine . The practitioner places their index and middle fingers behind the angle of the mandible to physically push the posterior aspects of the mandible upwards while ...
The Anti-Choking Trainer, developed by Act+Fast, LLC, is a light-weight neoprene vest that users wear to practice the abdominal thrust maneuver and backslap method. [7] There are two protocol models available: Act+Fast Red with a Back Slap Pad for the Red Cross Choking Rescue Protocol and Act+Fast Blue for the American Heart Association ...
Visual demonstration of jaw thrust. The jaw-thrust maneuver is an effective airway technique, particularly in patients in whom cervical spine injury is a concern. The jaw thrust is a technique used on patients with a suspected or possible cervical spinal cord injury and is used on a supine patient. The practitioner uses their index and middle ...
It is generally desirable in any aerobatic aircraft, as a high-thrust-to-weight ratio allows the aircraft to recover velocity quickly after a high-G maneuver. In particular, a thrust-to-weight ratio greater than 1:1 is a critical threshold, as it allows the aircraft to maintain and even gain velocity in a nose-up attitude; such a climb is based ...
Figure 1: Approximation of a finite thrust maneuver with an impulsive change in velocity. An impulsive maneuver is the mathematical model of a maneuver as an instantaneous change in the spacecraft's velocity (magnitude and/or direction) [3] as illustrated in figure 1. It is the limit case of a burn to generate a particular amount of delta-v, as ...
The Herbst maneuver (also known as a J-turn [1] [2]) is an air combat maneuver that uses post-stall technology such as thrust vectoring and advanced flight controls to achieve high angles of attack. [3] The Herbst maneuver allows an aircraft to quickly reverse direction using a combination of high angle-of-attack and rolling.
This maneuver and the jaw-thrust maneuver are two of the main tools of basic airway management. If cervical spine injury is a concern and/or the patient is immobilized on a long spine board and/or with a cervical collar ; the jaw-thrust maneuver can be used instead .
