The LUCAS can be used both in and out of the hospital setting. [6] [7] The 2015 European Resuscitation Council Guidelines for Resuscitation does not recommend using mechanical chest compression on a routine basis, but are good alternative for situations where it may be difficult or to maintain continuous high-quality compressions, or when it may be too strenuous on the medic to do so.

Mean airway pressure typically refers to the mean pressure applied during positive-pressure mechanical ventilation. Mean airway pressure correlates with alveolar ventilation, arterial oxygenation, [1] hemodynamic performance, and barotrauma. [2] It can also match the alveolar pressure if there is no difference between inspiratory and expiratory ...
Ventilation–perfusion coupling is the relationship between ventilation and perfusion processes, which take place in the respiratory system and the cardiovascular system. [1] Ventilation is the movement of gas during breathing, and perfusion is the process of pulmonary blood circulation , which delivers oxygen to body tissues. [ 2 ]
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 ...
Mechanical dead space or external dead space is volume in the passages of a breathing apparatus in which the breathing gas flows in both directions as the user breathes in and out, causing the last exhaled gas to be immediately inhaled on the next breath, increasing the necessary tidal volume and respiratory effort to get the same amount of ...
“I fear,” he said, that using ventilators “to increase pressure on the lungs in order to open them up, is actually doing more harm than good, and that the pressure we are providing to lungs ...
An iron lung is a type of negative pressure ventilator, a mechanical respirator which encloses most of a person's body and varies the air pressure in the enclosed space to stimulate breathing. [1] [2] It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability. [1]
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.
