Heat and moisture exchanger

Index Heat and moisture exchanger

Heat and exchange moisturizers (HME) are devices used in mechanically ventilated patients intended to help prevent complications due to "drying of the respiratory mucosa, such as mucus plugging and endotracheal tube (ETT) occlusion." HMEs are one type of commercial humidification system, which also include non-heated-wire humidifiers and heated-wire humidifiers. [1]

Acute respiratory distress syndrome

Acute respiratory distress syndrome (ARDS) is a medical condition occurring in critically ill or critically wounded patients characterized by widespread inflammation in the lungs.

Mechanical ventilation

Mechanical ventilation is the medical term for artificial ventilation where mechanical means is used to assist or replace spontaneous breathing. This may involve a machine called a ventilator or the breathing may be assisted by an anesthesiologist, certified registered nurse anesthetist, physician, physician assistant, respiratory therapist, paramedic, EMT, or other suitable person compressing a bag or set of bellows. Mechanical ventilation is termed "invasive" if it involves any instrument penetrating the trachea through the mouth, such as an endotracheal tube or the skin, such as a tracheostomy tube. There are two main types: positive pressure ventilation, where air (or another gas mix) is pushed into the trachea, and negative pressure ventilation, where air is, in essence, sucked into the lungs. There are many modes of mechanical ventilation, and their nomenclature has been revised over the decades as the technology has continually developed.

Stoma

In botany, a stoma (plural "stomata"), also called a stomata (plural "stomates") (from Greek στόμα, "mouth"), is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates gas exchange.

Tracheotomy

Tracheotomy, or tracheostomy, is a surgical procedure which consists of making an incision on the anterior aspect of the neck and opening a direct airway through an incision in the trachea (windpipe).
