Trial Title: Project 4A: Inspiratory Muscle Training and Diaphragm Strength

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: SINGLE
- Phase: PHASE1/PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* presence in the surgical or trauma ICU~* age of ≥18 years~* received mechanical ventilation (MV) for 3 days and expected to survive ICU stay~* ability to obtain informed consent from patient or proxy~Exclusion Criteria:~* Inability to speak and understand English~* Uncontrollable source of sepsis with imminent death (e.g., irreversible disease state, unresectable dead bowel)~* Receiving comfort care only or have advanced care directives limiting resuscitative efforts~* Known HIV infection with CD4 count \< 200 cells/mm~* Organ transplant recipients on immunosuppressive agent(s),~* Known pregnancy~* Unable to follow simple, one-step commands, such as breathe in as hard as you can!~* Prior arrangements to be transferred to other facilities before 28 days of treatment~* Contraindications to being disconnected from MV for sham or inspiratory muscle strength training treatment~* Unstable or difficult airway at 3 days of ICU care defined by ICU protocol, predicted to last for more than 72 hours~* Ongoing use of vasopressor or vasodilatatory agents for unstable blood pressure. (beyond minimal intermittent amount or renal perfusion dose,~* Severe cardiac dysrhythmias~* Esophageal varices or recent esophageal or gastric surgery,~* Upper-airway issues that would be aggravated by inserting esophageal pressure transducers~* Unstable neck/cervical anatomy that might be adversely impacted by bilateral magnetic stimulation of phrenic nerves at the neck~* Acute coronary syndrome~* Pulmonary contraindications (pneumon/hemothorax not drained, flail chest)~* Cardiac pacemakers and/or implanted defibrillator or other implanted electronic devices interfering with magnetic stimulation~* Implanted metal in the chest, neck or head, making magnetic stimulation contraindicated (dental fillings are permitted)~* Postoperative severe surgical problems interfering with the respiratory training (serious postoperative bleeding, wound dehiscence, etc.) - when and if these problems resolve and the patient meets other entry criteria, they will be eligible to be recruited for participation~* Active neuromuscular diseases that would prevent or interfere with responding to strength training (e.g. amyotrophic lateral sclerosis, multiple sclerosis, myasthenia gravis, polymyositis, muscular dystrophy or other dystrophies and myopathies)~* Any other factor that in the investigators' opinions would prevent response to training or create an unsafe condition for the patient.

Study Arms:
- IMST Intervention group (Type: EXPERIMENTAL): IMST will be conducted 5 days per week by study staff using a threshold inspiratory muscle training device (Respironics model 735). Prior to training, the tracheal cuff pressure is assessed to ensure no air leakage and appropriate inflation. The IMST training takes approximately 15 minutes to complete. To perform IMST, FiO2 is increased for 2 minutes prior to each training bout to maintain oxygen saturation more than 92%.
- SHAM group (Type: SHAM_COMPARATOR): SHAM training will also be conducted five days per week with an identical training device that has been modified by removing the valve leaflet, which essentially removes all inspiratory loading by the device. The modified SHAM device makes a whistling sound during inspiration, which enhances the sham effect. For SHAM treatment, supplemental oxygen FiO2 will be increased for two minute prior to each bout.

Based on this trial design, predict the completion outcome and termination type (if applicable).
