Pressure relief may refer to: stress management to relieve psychological stress on a human; relieving excessive pressure forces to protect a mechanical system, typically using a pressure-relief device such as a safety valve or rupture disc
A hug machine, also known as a hug box, a squeeze machine, or a squeeze box, is a therapeutic device designed to calm hypersensitive persons, usually individuals with autism spectrum disorders. The device was invented by Temple Grandin to administer deep-touch pressure , a type of physical stimulation often self-administered by autistic ...
The (FROPVD) has a peak flow rate of 100% oxygen at up to 40 liters per minute. To use the device, manually trigger it until chest rise is noted and then release. [2] Wait five seconds before repeating. The device must have a pressure relief valve that opens at 60cm of water pressure to avoid over ventilation and trauma to the lungs.
A rupture disc (burst) Pressure-effect acting at a rupture disc A rupture disc, also known as a pressure safety disc, burst disc, bursting disc, or burst diaphragm, is a non-reclosing pressure relief safety device that, in most uses, protects a pressure vessel, equipment or system from overpressurization or potentially damaging vacuum conditions.
At set pressure the valve snaps to full lift. This can be quite violent on large pipes with significant pressure. The pressure has to drop below the set pressure in order for the piston to reseat (see blowdown in relief valve article). Modulating The pilot is designed to open gradually, so that less of the system fluid is lost during each ...
Psychological first aid (PFA) is a technique designed to reduce the occurrence of post-traumatic stress disorder.It was developed by the National Center for Post Traumatic Stress Disorder (NC-PTSD), a section of the United States Department of Veterans Affairs, in 2006.

A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.
