[respiratory Failure].
Though the equation appears complex, it simply means that the oxygen tension in the alveoli is predominantly determined by the concentration of inspired oxygen, the barometric pressure and the carbon dioxide tension in the alveoli. Because carbon dioxide is very freely diffusible across the alveolar membrane, often arterial and alveolar carbon dioxide tension will be equal. That is why PaCO2 wh...
متن کاملRespiratory failure.
Definitions Acute respiratory failure describes any impairment in oxygenation or ventilation in which the arterial oxygen tension falls below 60 mm Hg (acute hypoxemia), the carbon dioxide tension rises above 50 mm Hg (acute hypercarbia, hypercapnia) and the pH drops below 7.35, or both. For patients who have underlying chronic respiratory failure, acute hypercarbia can be diagnosed by an incre...
متن کاملRespiratory failure.
Respiratory failure occurs due mainly either to lung failure resulting in hypoxaemia or pump failure resulting in alveolar hypoventilation and hypercapnia. Hypercapnic respiratory failure may be the result of mechanical defects, central nervous system depression, imbalance of energy demands and supplies and/or adaptation of central controllers. Hypercapnic respiratory failure may occur either a...
متن کاملPapilloedema and respiratory failure.
Papilloedema is a rare but well recognised complication of respiratory failure that was first described in 1933 in a patient with pulmonary emphysema.' Several cases have been reported of patients with respiratory failure and papilloedema who developed optic atrophy and blindness.23 We report on a patient who presented with loss of vision and papilloedema secondary to the obesity hypoventilatio...
متن کاملNeurological Respiratory Failure
West Nile virus infection in humans is mostly asymptomatic. Less than 1% of neuro-invasive cases show a fatality rate of around 10%. Acute flaccid paralysis of respiratory muscles leading to respiratory failure is the most common cause of death. Although the peripheral nervous system can be involved, isolated phrenic nerve palsy leading to respiratory failure is rare and described in only two c...
