TLC, EELV, RV) and the method used in measurement should be specified and the value should be expressed as % pred [28, 29]. The role of other potential contributors to lung hyperinflation, such as re-setting of the passive elastic properties of the chest wall or active inspiratory muscle and laryngeal braking during expiration, remains uncertain in COPD [1113].

Congenital lobar emphysema (CLE) is a rare lung malformation that occurs when air become trapped in the lungs.

Expiratory flow limitation (EFL) is the pathophysiological hallmark of chronic obstructive pulmonary disease (COPD) and arises because of the dual effects of permanent parenchymal destruction (emphysema) and airway dysfunction, which in turn reflect the effects of small airway inflammation (mucosal oedema, airway remodelling and mucous impaction) and possibly increased cholinergic airway smooth muscle tone (fig.

At this threshold, tidal volume becomes fixed on the upper less compliant extreme of the respiratory system's sigmoid-shaped pressurevolume relationship, where there is increased elastic loading of the inspiratory muscles.

The scans showed air trapping, which indicates small airway disease. Observations of Covid-19 illness in patients with/without MCAS were compared with extensive clinical experience with MCAS.

All of the above factors are clearly interdependent and contribute in a complex, integrated manner to dyspnoea and exercise limitation in COPD. According to different Hounsfield unit (HU) intervals in the quantitative chest CT scan, we divided each lung into nonaerated lung volume (%NNL, 100 to -100 HU), poorly aerated lung volume (%PAL, -101 to -500 HU), normally aerated lung volume (%NAL, -501 to -900 HU), and hyperinflated lung volume (%HI, -901 to -1000 HU) regions.

A first-of-its kind study finds evidence of a link between gut dysbiosis and the development of long COVID.

A number of studies have shown several structural adaptations to chronic intrinsic mechanical loading, which include the following: 1) reduction in sarcomere length, which improves the ability of the muscle to generate force at higher lung volumes [43]; 2) an increase in the relative proportion of type I fibres, which are slow-twitch and fatigue resistant [44, 45]; and 3) an increase in mitochondrial concentration and efficiency of the electron transport chain, which improves oxidative capacity [43]. Review/update the Reyes FM, Modi P, Le JK. They include: Stridor refers to a high-pitched sound with a musical quality that is heard mostly with inspiration; it is typically loudest over the neck.

Bronchial breath sounds are heard over the large bronchi when the doctor moves the stethoscope over the breastbone or sternum in the mid-chest region and between the shoulder blades on the back.

Air trapping refers to pockets of air that become trapped in the lung after breathing out.
