Analysis of α-lipoprotein cholesterol in 50 μl of plasma

open access: yesJournal of Lipid Research, 1974
A micromethod for quantitation of α-lipoprotein cholesterol was devised for gas–liquid chromatography to minimize plasma sample size and facilitate lipid studies using capillary blood from children or small animals. α-Lipoprotein cholesterol was measured

Mathematical modelling of a human external respiratory system [PDF]

open access: yes
A closed system of algebraic and common differential equations solved by computer is investigated. It includes equations which describe the activity pattern of the respiratory center, the phrenic nerve, the thrust produced by the diaphragm as a function ...

Lung Circulation Modeling: Status and Prospect [PDF]

open access: yes, 2006
Mathematical modeling has been used to interpret anatomical and physiological data obtained from metabolic and hemodynamic studies aimed at investigating structure-function relationships in the vasculature of the lung, and how these relationships are ...

Calculated arterial blood gas values from a venous sample and pulse oximetry: Clinical validation

open access: yesPLoS ONE, 2019
Background Arterial blood gases (ABG) are essential for assessment of patients with severe illness, but sampling is difficult in some settings and more painful than for peripheral venous blood gas (VBG).

Evaluation of the Appropriate Root Pressure for Maintaining Heartbeat during an Aortic Cross-clamp for Primary Repair of the Aortic Arch in Premature Infants with Associated Cardiac Anomalies [PDF]

open access: yes, 2010
We developed a new cardiopulmonary bypass (CPB) method to minimize myocardial damage during aortic arch reconstruction. In this method, coronary flow and heartbeat were stabilized by maintaining the aortic root pressure with an adjusted preload of the ...

Monro-Kellie 2.0: The dynamic vascular and venous pathophysiological components of intracranial pressure [PDF]

open access: yes, 2016
For 200 years, the ‘closed box’ analogy of intracranial pressure (ICP) has underpinned neurosurgery and neuro-critical care. Cushing conceptualised the Monro-Kellie doctrine stating that a change in blood, brain or CSF volume resulted in reciprocal ...

Does traffic‐related air pollution exposure alter blood gas parameters in recreationally trained male cyclists during prolonged endurance exercise?

open access: yesPhysiological Reports
Exposure to air pollution has been a significant challenge in large cities as São Paulo, Brazil, particularly for individuals exercising outdoors. The increasing on ventilation (VE) during physical effort can lead to greater pollutant inhalation.

Prediction of arterial blood ph and partial pressure of carbon dioxide from venous blood samples in patients receiving mechanical ventilation

open access: yesJournal of Medical Signals and Sensors, 2013
Substitution of arterial with venous blood samples to estimate blood gas status is highly preferable due to practical and safety concerns. Numerous studies support the substitution of arterial by venous blood samples, reporting strong correlations ...
