Abstract:

A lung simulator utilizing flow track to simulate spontaneous breathing is presented as an alternative to the existed lung system in the medical patient simulator. The hardware of simulator is similar and updated from Meka’s paper. The existing lung system can be divided into two main types. One is traditional bellows driven mechanical lung system, the other is bellow-less lung simulator driven by carinal pressure that to be controlled. Our lung simulator is upgraded from bellow-less simulator. The research focus on the flow pattern the lung simulator generated which can image the lung mechani

Abstract:

The complex, multicameral lungs of the Nile crocodile are characterized by rows of tubular chambers, which in cranial and ventral lung regions are broad and sac-like. The inner surface of the chambers is enhanced by cubicles (ediculae), the capillary-bearing walls of which are often perforated. Extrabronchial communication among chambers is infrequent. The ediculae end in a network of myoelastic trabeculae, which face the central lumen of the chambers. The trabecular epithelium is similar to that of mammalian bronchi and contains isolated endocrine-like cells basally, whereas the edicular epit

Abstract:

Thermal burns are one of the most traumatic and physically exhausting injuries. Among the many factors that are decisive for a burn injury, the relationship between the temperature of the damaging agent and the duration of exposure is important. The term of exposure and high temperature determine the depth of the lesion. During burns, hypoxic, hemodynamic and metabolic disorders occur, which lead to changes in the structures and functions of internal organs. There are various ways of developing the respiratory system disorders after a burn injury to the skin: direct thermal damage to the respi

The receptor for advanced glycation end-products (RAGE) and its soluble forms are predominantly expressed in lung but its physiological importance in this organ is not yet fully understood.

Respiratory function in a buffer-perfused isolated lung system and biochemical parameters of the lung were studied in young, adult, and old RAGE knockout (RAGE-KO) mice and wild-type (WT) mice. Lungs from RAGE-KO mice showed a significant increase in the dynamic lung compliance and a decreas

Abstract:

One of the leading trends in modern medicine is the principle of prevention, which consists in preventing the formation of diseases and complications of therapy. The main damaging factor during respiratory support in patients with inhomogeneous lung tissue injury is tidal volume (TV). With traditional pressure controlled mechanical ventilation (PCMV), controlling the TV delivered to the child is difficult due to the variable mechanical properties of the lung tissue. PCMV algorithms with targeted TV, used in neonatology and in young children, make it possible to adjust the parameters of endotra

Background and Objectives: Intra-abdominal hypertension (IAH) and acute respiratory distress syndrome (ARDS) are common concerns in intensive care unit patients with acute respiratory failure (ARF). Although both conditions lead to impairment of global respiratory parameters, their underlying mechanisms differ substantially. Therefore, a separate assessment of the different respiratory compartments should reveal differences in respiratory mechanics.

Bronchopulmonary dysplasia (BPD) is a chronic lung disease of multifactorial etiology characterized by the formation of respiratory failure and regressing as the child grows. With a severe form of BPD, adequate and safe respiratory support is required for a long time. The mechanical properties of the lungs in these patients differ significantly from those in acute respiratory pathology, which should be taken into account when setting the parameters of the ventilator.
