It is conventionally defined by an arterial oxygen tension (P a,O 2) of <8.0 kPa (60 mmHg), an arterial carbon dioxide tension (P a,CO 2) of >6.0 kPa (45 mmHg) or both. He created the ‘Critically Ill Airway’ course and teaches on numerous courses around the world. Patients suffering from COPD exacerbation, regardless of whether they have CO2 retention, generally have supra-normal respiratory drive (unless there is impending hypercapnic coma), In COPD, patients optimise their gas exchange by hypoxic vasoconstriction leading to altered alveolar ventilation-perfusion (Va/Q) ratios, Excessive oxygen administration overcomes this, leading to increased blood flow to poorly ventilated alveoli, and thus increased Va/Q mismatch and increased physiological deadspace, this increase in Va/Q mismatch occurs in both CO2 retainers and non-retainers, the difference is presumably one of degree, deoxygenated hemoglobin (Hb) binds CO2 with greater affinity than oxygenated hemoglobin (HbO2), hence oxygen induces a rightward shift of the CO2 dissociation curve, which is called the Haldane effect, in patients with severe COPD who cannot increase minute ventilation, the Haldane effect accounts for about 25% of the total PaCO2 increase due to O2 administration, the targeted approach is associated with decreased mortality in COPD patients and less respiratory acidosis, The oxygen flow rate administered is not important, the (alveolar) PAO2 (and, indirectly, the SaO2) achieved is, Never withhold oxygen from a seriously ill hypoxic patient due to fear of cause hypercapnic respiratory failure. Cyanotic congenital heart disease. Respiratory Failure. Patients suffering from COPD exacerbation, regardless of whether they have CO2 retention, generally have supra-normal respiratory drive (unless there is impending hypercapnic coma) It showed type one respiratory failure with a p02 of 10.0 and a pCO2 of 4.1.

The medical management of patients with acute respiratory failure will vary depending on the cause and type of failure. If this is the cause of respiratory failure it should be treated and a safe airway maintained as a priority.

Hypoxemic respiratory failure (type 1): Usually is the result of the lung’s reduced ability to deliver oxygen across the alveolocapillary membrane. Pneumothorax. The severity of gas exchange impairment is determined by calculating the P(A–a) O 2 gradient (A-a gradient) using the alveolar gas equation:. Others include chest-wall deformities, respiratory muscle weakness (e.g. Bronchiectasis.

Defined as the buildup of carbon dioxide levels (P a CO 2) that has been generated by the body but cannot be eliminated. Respiratory failure is characterized by a reduction in function of the lungs due to lung disease or a skeletal or neuromuscular disorder. Respiratory failure is a condition in which the respiratory system fails in one or both of its gas exchange functions, i.e. Respiratory Failure in the Haematology/Oncology patient, Causes in the Haematology/Oncology patient, -> cardiovascular-> respiratory-> abdominal (distension), -> paralysed-> quick examination-> unconscious-> conscious. 7.

Type 1 & Type 2 respiratory failure. Pulmonary oedema. Respiratory failure is, by definition, a failure of gas exchange. The morbidity and mortality from the consequent disturbance in acid-base balance can be significant. It occurs when gas exchange at the lungs is significantly impaired to cause a drop in blood levels of oxygen(hypoxemia) occurring with or without an increase in carbon dioxide levels (hypercapnia). The manifestation of paradoxical breathing depends on its cause. 10. Respiratory revision notes covering key respiratory conditions including asthma, COPD, pneumonia and more.
