Clinical applications of the respiratory equation of motion to guide decision-making in the patient under invasive mechanical ventilation

Iatreia, 2023
Introduction: Mechanical ventilation is a common practice in intensive care units and anesthesiology with both therapeutic and potentially harmful implications for the respiratory system and distant organs, that is why it is of utmost importance to ...

Evaluating the effects of vitamin D Level on airway obstruction in two asthma endotypes in humans and in two mouse models with different intake of vitamin D during early-life

Frontiers in Immunology, 2023
IntroductionAsthma is primarily divided into two categories: type 2 (T2-high) and non-type 2 (T2-low). A relationship between asthma severity and vitamin D deficiency has been identified, but its impact on each asthma endotype remains unknown.MethodsWe ...

Risk factors for Haemophilus influenzae and pneumococcal respiratory tract colonization in CVID [PDF]

, 2018
To the Editor: Disease-specific studies focused on infection risk in common variable immune deficiencies (CVIDs) are needed to define strategies for controlling respiratory infections predominantly due to bacteria such as Streptococcus pneumoniae and ...

A novel approach in understanding the basic modes of ventilation in a recent generation mechanical ventilator– A review of the underlying principles

Indian Journal of Anaesthesia, 2023
Understanding the basic concepts and the dynamics of the equation of motion will help the anaesthesiologist and the intensive care physician in gaining an insight into the basics of modern mechanical ventilation. An equation of the type Vt = V0 × (1-e-kt)

Effects of Inhaled Brevetoxins in Allergic Airways: Toxin–Allergen Interactions and Pharmacologic Intervention [PDF]

, 2005
During a Florida red tide, brevetoxins produced by the dinoflagellate Karenia brevis become aerosolized and cause airway symptoms in humans, especially in those with pre-existing airway disease (e.g., asthma).

Impulse oscillometry may be of value in detecting early effects of obesity on airway resistance

Egyptian Journal of Chest Disease and Tuberculosis, 2019
Background and objective Obesity as a major nutritional problem is badly associated with respiratory compliance. The effortless technique such as impulse oscillometry system (IOS) could have a supremacy value over the commonly used pulmonary function ...

Relationship between pre-anesthetic and intra-anesthetic airway resistance in patients undergoing general anesthesia: A prospective observational study. [PDF]

PLoS ONE, 2017
Surgery patients in Japan undergo routine spirometry testing prior to general anesthesia. The use of a flow sensor during general anesthesia has recently become common. However, it is not certain whether the information derived from flow-volume curves is
