NCT01668368

Brief Summary

Patients with acute respiratory failure exhibiting decreased respiratory system compliance with hypoxemia or carbon dioxide retention are often difficult to ventilate with current guidelines that limit applied plateau pressure Yet, these guidelines do not take into consideration chest wall mechanics. The investigators sought to determine whether partition of the respiratory system into its components by measuring esophageal pressure and thus assessment of pleural pressure, would help in patients with acute respiratory failure to identify the factors contributing to low respiratory system compliance.

Outcome Measures

Primary Outcomes (1)

  • Oxygenation

    1 year

Secondary Outcomes (1)

  • lung compliance, expressed as ml/cmH2O.

    1 year

Study Arms (1)

Esophageal balloon group

OTHER

Esophageal balloon will be inserted, and esophageal pressure will be measured in patients with acute respiratory failure. Intervention - PEEP and Inspiratory pressure will be adjusted according to the measured esophageal pressure.

Other: esophageal balloon

Interventions

esophageal pressure as a surrogate for pleural pressure

Also known as: pleural pressure
Esophageal balloon group

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Low Total Respiratory system compliance (CT), defined as less than 50ml/cmH2O. 2 - P/F ratio of less than 300. 3 - Need for a PEEP greater than 10 cmH2O to maintain SaO2 of \> 90%. 4 - PCO2 over 60 mmHg, or PH less than 7.2 that is attributed to respiratory acidosis.

You may not qualify if:

  • Patients with any of the following were excluded from the study. Previous lung or chest wall surgery, previous esophageal surgery, known Achalasia or any other esophageal motility or spasm disorder, presence of chest thoracostomy tube, and any significant chest wall abnormality such as kyphoskoliosis.
