Brief Summary:
The aim of this study is to see if the Vapotherm High Flow Therapy (HFT) device is effective to provide breathing support to patients with Chronic Obstructive Pulmonary Disease or COPD. The investigators believe that patients using HFT will not require as much use of therapies that provide pressure through a face mask, and are already recognized by FDA as support therapies for respiratory insufficiency.

Condition or disease Intervention/treatment Phase
Pulmonary Disease, Chronic Obstructive Respiratory Insufficiency Device: Vapotherm High Flow Therapy Not Applicable

Detailed Description:
The overall objective of this study is to demonstrate that Vapotherm High Flow Therapy (HFT) via nasal cannula provides respiratory support to patients with COPD as a primary diagnosis, who present with respiratory insufficiency in the Emergency Department. We intend to demonstrate that Vapotherm HFT via nasal cannula will result in at least equivalent patient outcomes as the current standard of care, while eliminating the need for other non-invasive respiratory support devices cleared for the treatment of respiratory insufficiency. The current standard of care will include the use of other devices cleared by the FDA as respiratory assist devices for the treatment of adult respiratory insufficiency.

Arm Intervention/treatment
Experimental: High FLow Therapy
Use of High Flow Therapy for support of Respiratory Insufficiency
Device: Vapotherm High Flow Therapy
use of high flow nasal cannula to support oxygenation and CO2 removal by flushing the nasopharynx with warmed, humidified respiratory gas at flow rates that exceed a patient's inspiratory flow rate
Other Name: high flow nasal cannula

  4. Pulse Ox and FIO2 [ Time Frame: 0, 2, 4 hrs ]
  5. Intensive Care Unit admission rate / Length of Stay [ Time Frame: 7 days ]
  6. Hospital Length of Stay [ Time Frame: 7 days ]
  7. Total duration of NIPPV/PPV or Vapotherm oxygen delivery [ Time Frame: 7 days ]
  8. Integrated FIO2 exposure [ Time Frame: 7 days ]
  9. Physician assessment - retractions, physician judgment of patient discomfort [ Time Frame: 0, 2, 4 hrs ]
