N Equipment and Techniques for Noninvasive Ventilation
livery of mechanical ventilation to patients with respiratory failure without the requirement of an artificial airway. The key change that led to the recent increase in the use of this technique occurred in the early 1980s with the introduction of the nasal continuous positive airway pressure mask for the treatment of obstructive sleep apnea. Studies published in the 1990s that evaluated the ef...
متن کاملMechanical Ventilation and Equipment
Mechanical ventilation systems for controlling conditions in individual zones can move a constant or variable supply of conditioned air to handle all or some of the heating and cooling loads. They are classified as all-air, air-water, and all-water systems. All-air systems include single-duct, dual-duct and multizone. The systems can be designed to operate at Constant Air Volume (CAV) or Variab...
متن کاملAssisted ventilation. 5. Non-invasive and domiciliary ventilation: negative pressure techniques.
Historical development Negative pressure ventilation first came into use during the second half of the nineteenth century. It was recognised that air would be drawn into the lungs through the mouth and nose if a subatmospheric pressure could be developed around the thorax and abdomen. When the pressure around the -chest wall returned to that of the ambient air, expiration occurred passively owi...
متن کاملAssisted ventilation 6. Non-invasive and domiciliary ventilation: positive pressure techniques.
Intermittent positive pressure ventilation through an endotracheal or tracheostomy tube has been the mainstay of respiratory assistance for several decades. Some patients have been discharged home with a positive pressure device and tracheostomy but the number treated by these means in Britain has always been small.' Securing adequate gas exchange is usually easy and differs very little from th...
متن کاملPrinciples of artificial ventilation
Ventilators are commonly used in the operating theatre and in the ICU to deliver mechanical ventilation to the lungs. In the operating theatre, ventilation is given to anaesthetized and often pharmacologically paralysed patients with predominantly normal lungs. These ventilators are relatively simple and are designed to deliver varying concentrations of oxygen, air, nitrous oxide and volatile a...
