When having drawn a curve with the relations between changes in volume to changes in transpulmonary pressure, C st is the slope of the curve during any given volume, or, mathematically, ΔV/ΔP. [23] Static lung compliance is perhaps the most sensitive parameter for the detection of abnormal pulmonary mechanics. [ 24 ]
A tracheal tube is a catheter that is inserted into the trachea for the primary purpose of establishing and maintaining a patent (open and unobstructed) airway. Tracheal tubes are frequently used for airway management in the settings of general anesthesia, critical care, mechanical ventilation, and emergency medicine. Many different types of ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

Notably, spirometers have been used to evaluate vital capacity in India since 1929, recording a statistically significant difference between males (21.8 mL/cm) and females (18 mL/cm). [14] Additionally, by 1990, around half of pulmonary training programs in both the United States and Canada adjusted for race and ethnicity.
Tidal volume (Vt) is the volume inspired and expired with each breath. Variability in the wave form can be used to differentiate between restrictive (less) and obstructive pulmonary diseases as well as acute anxiety. Minute ventilation is equivalent to tidal volume multiplied by respiratory rate and is used to assess metabolic activity.
Mechanical ventilation or assisted ventilation is the medical term for using a ventilator machine to fully or partially provide artificial ventilation.Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide.
In the developed world, the most frequent type in use is the continuous-flow anaesthetic machine or "Boyle's machine", which is designed to provide an accurate supply of medical gases mixed with an accurate concentration of anaesthetic vapour, and to deliver this continuously to the patient at a safe pressure and flow.
% = Using the deviation from desirable weight, the BV ratio (ml/kg), i.e. Ideal Blood Volume, can be determined. The machine was tested in clinical studies for the treatment of a broad range of medical conditions related to Intravascular Volume Status, such as anemia, [4] congestive heart failure, [5] sepsis, [6] CFS, [7] Hyponatremia, [8 ...
