Pulsus paradoxus in ventilated and non-ventilated patients.

  author={Frankie W. H. Wong},
  volume={18 3},
Human physiology changes are often amplified in disease states and may be altered when a patient is mechanically ventilated. Normally, systolic blood pressure is slightly lower during inspiration than expiration due to the change in intrathoracic pressure. Pulsus paradoxus is a phenomenon in which the difference in systolic blood pressure (BP) between inspiration and expiration is more than 10 mmHg. When a patient is mechanically ventilated, the pattern of changes observed in pulsus paradoxus… 

Prediction of fluid responsiveness in ventilated critically ill patients

This paper presents a comprehensive review of the various static and dynamic measurements used to study fluid responsiveness in critically ill patients with cardiocirculatory shock.

Post-extubation Stridor

While endotracheal intubation is often necessary to facilitate mechanical ventilation for critically ill children, it has been associated with the development of upper airway obstruction upon extubation and results in short-term morbidity with increased length of mechanical ventilation and intensive care unit (ICU) length of stay.

Predicting fluid responsiveness: A review of literature and a guide for the clinician



Measurement of pulsus paradoxus.

Critical care nurses need to become familiar with the three methods of measuring pulsus paradoxus: palpation, cuff sphygmomanometry, and arterial wave formation to become skilled at measuring a greater than 10 mm Hg change.

Comparison of traditional and plethysmographic methods for measuring pulsus paradoxus.

Measurement of PP using the pulse oximeter-pulse plethysmographic waveform offers a simple and noninvasive method for evaluating patients with airway obstruction.

Analysis of physician ability in the measurement of pulsus paradoxus by sphygmomanometry.

Past and present guidelines do not account for the challenges in measuring PP, especially in tachypneic patients, and sphygmomanometric determination of PP should be augmented by new aids developed through technological innovation.

Abnormal septal motion in cardiac tamponande with pulse paradoxus. Echocardiographic and hemodynamic observations.

In a patient with cardiac tamponade and pulses paradoxus the echocardiogram showed markedly abnormal septal motion, consisting of posterior displacement during inspiration, which support the hypothesis that pulsus paradoxus may be caused by competition of the ventricles for filling within a relatively rigid pericardial space.

An alternative method for coordinating pulmonary capillary wedge pressure measurements with the respiratory cycle.

With certain newer ventilators, the machine-pressure and/or expiratory-flow signal can be graphed simultaneously with hemodynamic pressure, and the end-expiratory point determined from these graphs can be used to identify the corresponding wedge pressure on the hemodynamic tracing.

Detection of pulsus paradoxus associated with large pericardial effusions in pediatric patients by analysis of the pulse-oximetry waveform.

Analysis of pulse-oximetry waveforms may be a widely available, easily interpretable, and reliable method of detecting the pulsus paradoxus associated with large pericardial effusions in pediatric patients.

It is concluded that advanced nursing practice presents an opportunity for the combination of the art of nursing and advanced tasks, but that new roles must develop within a recognized framework which takes account of the educational, ethical and legal accountability issues.
