Title: Patient Outcomes 6 and 12 Months After ALTA, OMEGA, EDEN and SAILS ARDS Network Trials
Brief Summary: Acute lung injury (ALI) is a severe lung condition that causes respiratory failure. The ARDS Network (ARDSNet) is a National Heart, Lung, and Blood Institute-sponsored network that is focused on improving treatments for people with ALI and a similar condition called acute respiratory distress syndrome (ARDS). This study will evaluate participants who were enrolled in one of three ARDSNet studies to examine how the treatments carried out in the prior studies affect participants' long-term health outcomes and quality of life.


Options:
A: Inclusion Criteria:

* All patients admitted to the participating ICUs receiving invasive or non-invasive ventilation will be screened and included in the database.

Exclusion Criteria:

* Age \< 16
B: Inclusion Criteria:

* Age ≥18 years old
* Patients must have acute onset of ARDS, as defined by the American-European Consensus Conference (AECC) criteria for ARDS: (i) having an initiating clinical condition (pneumonia, aspiration, inhalation injury, sepsis, trauma, acute pancreatitis, etc.; (ii) bilateral infiltrates on frontal chest radiograph; (iii) absence of left atrial hypertension, a pulmonary capillary wedge pressure (PCWP) less than 18 mm Hg, or no clinical signs of left heart failure; (iv) severe hypoxemia (a PaO2/FIO2 \<200 mm Hg, regardless of FIO2 or positive end-expiratory pressure (PEEP)
* Be intubated and mechanically ventilated
* Have provided signed written informed consent from the patient or the patient's personal legal representative

Exclusion Criteria:

* Be a woman known to be pregnant or lactating
* Take part in another experimental treatment protocol (simultaneously)
* Brain death
* Terminal-stage cancer or other terminal disease
* Having do-not-resuscitate orders
* Being immune-compromised
* Receiving corticosteroids or immunosuppressive drugs
* Patients in whom more than 24 hours had elapsed after initially meeting the AECC ARDS criteria before consent and results of initial standard ventilator settings could be obtained.
* Have severe chronic obstructive pulmonary disease (COPD)
* Have congestive heart failure
C: Inclusion Criteria:

* Participated in the ALTA, EDEN, OMEGA, or SAILS study
* Survived until hospital discharge

Exclusion Criteria:

* Does not understand or speak English
* Has no fixed address
* Pre-existing cognitive impairment that prevents completion of the study assessments
D: Inclusion Criteria:

* Must meet the following three criteria within a 24-hour period:

  1. Acute onset of PaO2/FiO2 less than or equal to 300 (adjustments made for altitude where appropriate)
  2. Bilateral infiltrates consistent with pulmonary edema on frontal chest radiograph
  3. Requirement for positive pressure ventilation via endotracheal tube
* No clinical evidence of left-sided cardiac failure to account for bilateral pulmonary infiltrates

Exclusion Criteria:

* Greater than 48 hours since all inclusion criteria are met
* Neuromuscular disease that impairs ability to ventilate without assistance, (e.g., cervical spinal cord injury at level C5 or higher spinal cord injury amyotrophic lateral sclerosis, Guillain-Barré syndrome or myasthenia gravis)
* Pregnant or breast-feeding
* Severe chronic respiratory disease (i.e., chronic hypercapnia \[PaCO2 greater than 45 mmHg\], chronic hypoxemia \[PaO2 less than 55 mmHg on FiO2 = 0.21\], hospitalization within the last 6 months for respiratory failure \[PaCO2 greater than 50 mm Hg and/or PaO2 less than 55 mmHg on 0.21 FiO2\], secondary polycythemia, severe pulmonary hypertension \[mean PAP (pulmonary artery pressure) greater than 40 mmHg\], or ventilator dependency)
* Burns over greater than 40% of total body surface area
* Cancer or other irreversible disease or condition for which 6-month mortality is estimated to be greater than 50%
* Allogeneic bone marrow transplant within the 5 years prior to study entry
* Participant, surrogate, or physician is not committed to full support (Exception: a participant will not be excluded if he/she would receive all supportive care except for attempts at resuscitation from cardiac arrest)
* Severe chronic liver disease (Child-Pugh score of 11-15)
* Diffuse alveolar hemorrhage from vasculitis
* Morbid obesity (greater than 1kg/cm body weight.)
* Unwillingness or inability to utilize the ARDS network 6 ml / kg Predicted Body Weight (PBW) ventilation protocol
* Moribund participant and is not expected to survive 24 hours
* No intent to obtain central venous access for monitoring intravascular pressures
* Contraindication to aerosolized albuterol (see Appendix A.8 of the protocol for more information)
* Daily use (prior to study hospitalization) of inhaled beta agonist, corticosteroid, or oral leukotriene modifier
* Unwillingness of primary physician to discontinue inpatient beta agonist use
* Acute myocardial infarction or acute coronary syndrome within 30 days of study entry
* Severe congestive heart failure (see Appendix A5 of the protocol for more information)
* Participation in other experimental medication trial within 30 days of study entry with the exception of the ARDSNet pharmaconutrient nutrition trial (OMEGA)
* Heart rate greater than 85% of maximal predicted heart rate (MHR85) as calculated by MHR85 = 85% x (220-age)
* Currently receiving high frequency ventilation
