Escape hoods are emergency breathing apparatus that entirely cover the head and provide a few minutes of autonomy to escape from a dangerous area.The main configurations are the smoke hood, which has a carbon monoxide and particulate filter, and the more general purpose escape hood which has an air purification cartridge that also removes other ...
Smoke hoods present on aircraft, also called protective breathing equipment (or PBEs), typically generate oxygen for anywhere from 30 seconds to 15 minutes. The oxygen is kept in a closed circuit, usually thanks to a tight neck seal. A scrubber system may be present to reduce the levels of carbon dioxide, and is breathable for around 20 minutes ...
Oxygen therapy often benefits patients by providing more oxygen to their lungs and consequently to their tissues. Typically, the treatment raises the amount of oxygen in the blood, decreases load on the heart, and facilitates breathing. It can ease symptoms such as cough and dried up secretions that occur in respiratory conditions.
For substances hazardous to the eyes, a respirator equipped with a full facepiece, helmet, or hood is recommended. Air-purifying respirators are not effective during firefighting, in oxygen-deficient atmosphere, or in an unknown atmosphere; in these situations a self-contained breathing apparatus is recommended instead.

The user respiratory interface is the delivery system by which the breathing apparatus guides the breathing gas flow to and from the user. Some form of facepiece, hood or helmet is usual, but for some medical interventions an invasive method may be necessary. Any given unit is a member of several types.
They may use a breathing hood, facepiece or mouthpiece and nose-clip as the user respiratory interface. Atmosphere-supplying apparatus may be rebreathers with a chemical or compressed gas oxygen supply, positive pressure demand apparatus, or constant flow apparatus using high pressure compressed air. Contamination of the breathing gas may be ...
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
Blood pressure monitor: The blood pressure monitor is a machine that's connected to a small cuff which is wrapped around the arm or leg of the patient. This cuff automatically takes the blood pressure and displays the data for review by care providers. Oxygen hood: This is a clear box that fits over the baby's head and supplies oxygen.
