Brief Summary

The proposed study will be conducted to investigate the mechanism of patients' responses to prone positioning with coronavirus disease 2019 (COVID-19) acute respiratory distress syndrome (ARDS) and non-COVID-19 ARDS utilizing lung ultrasound.

Outcome Measures

Primary Outcomes (1)

  • Oxygenation and Lung Ultrasound Score (LUS)

    Patients' responses of oxygenation and lung ultrasound score (0 - 36 where 0 = normal lung aeration and 36 = most severe lung consolidation) to prone positioning in the first three prone positioning sessions for ARDS patients.

    10 months

Secondary Outcomes (1)

  • COVID-19 ARDS vs non-COVID-19 ARDS

    10 months

Study Arms (1)

Intubated ARDS patients undergoing prone positioning

All intubated ARDS patients undergoing prone positioning will be assessed with LUS before and after prone positioning and before and after placing back in the supine position.

Other: Lung Ultrasound (LUS)

Interventions

Enrolled subjects will undergo LUS 1 hour before and 1 hour after prone positioning by a trained clinician and will be assessed using a LUS score based on LUS pattern. LUS will then be performed again 1 hour before supination (16 hours) and assessed by a LUS score. This process will be repeated on the first 3 prone sessions. Patients will be enrolled in the study for 4 weeks in order to observe patient outcomes.

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

You may qualify if:

  • Adult subjects 18 years and older, diagnosis of ARDS
  • endotracheally intubated and receiving assisted mechanical ventilation

  • receive an order for prone positioning.

You may not qualify if:

  • Pregnant
  • Tracheostomy
  • Receiving ECMO
  • Palliative care
  • Receive prone positioning more than once during intubation in an outside hospital
  • Receive invasive ventilation in an outside hospital for more than 72 hours
