Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
Ventilator-associated pneumonia (VAP) is a type of lung infection that occurs in people who are on mechanical ventilation breathing machines in hospitals. As such, VAP typically affects critically ill persons that are in an intensive care unit (ICU) and have been on a mechanical ventilator for at least 48 hours.
The liquid ventilator with advanced control temperature of PFC allows the rapid cooling of the body. Consequently, therapeutic hypothermia is an expected clinical application. For example, studies present that rapid cooling instituted by TLV can improve cardiac and mitochondrial function [ 18 ] or can induce favorable neurological and cardiac ...
Hypoxic ventilatory response (HVR) is the increase in ventilation induced by hypoxia that allows the body to take in and transport lower concentrations of oxygen at higher rates. It is initially elevated in lowlanders who travel to high altitude, but reduces significantly over time as people acclimatize .
A liquid cooling and ventilation garment (LCVG) has additional crush-resistant ventilation ducts, which draw moist air from the wearer's extremities, keeping the wearer dry. In a fully enclosing suit where exhaled breathing air can enter the suit, the exhaled air is moist and can lead to an uncomfortable feeling of dampness.
The life-support system may supply air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences such as radiation and micro-meteorites may also be necessary.
At least 24 COVID-19 patients in western India died on Wednesday when the oxygen supply to their ventilators ran out, amid a nationwide shortage of the gas and a surge in infections. Maharashtra ...
The body can compensate to some extent by increasing the volume of inspired gas, but this also increases work of breathing, and is only effective when the ratio of dead space to tidal volume is reduced sufficiently to compensate for the additional carbon dioxide load due to the increased work of breathing.
