This is an interventional treatment trial for Diabetes Mellitus, Type 1 focused on measuring diabetes, time in range, inhaled insulin, continuous glucose monitoring, type 1 diabetes, hypoglycemia, post prandial hypergylcemia Read More

Inclusion Criteria:

2. Male or female aged 18-70 years,
3. Type 1 diabetes mellitus (T1D) duration more than six months
4. Treatment with multiple daily injections (MDI) for at least three months before screening visit; stable insulin dose for the last one month,
5. No use of any oral anti-diabetics, any other form of insulin other than mentioned in the protocol, or any other type of injections such as glucagon-like-peptide-1 (GLP-1) analogs, pramlintide or insulin/GLP-1 analog combinations,
6. A1c between 6.5 to 10%,
7. Willingness to routinely collect at least two blood glucose measurements per day needed to calibrate the CGM.

13. Patients who eat three main meals in a day (breakfast, lunch, and dinner),
14. Patients who use insulin-carb ratio for bolus,
15. Ability to speak, read, and write English, and
16. Patients prandial insulin need must be <18 units per meal

4. Use of systemic or inhaled corticosteroids,
5. History of hemoglobinopathies,
6. Diagnosis of anemia,
7. Post-renal transplantation, currently undergoing dialysis, creatinine >2.0 mg/dl or a calculated creatinine clearance of <50 mL/min,

10. Extensive skin changes/diseases that inhibit wearing a sensor on normal skin,
11. Known allergy to adhesives,
12. Known allergy to study medication,
13. Participation in another investigational study protocol within 30 days before enrollment,
14. Known chronic obstructive pulmonary disease, pulmonary hypertension, asthma, pulmonary fibrosis, or any chronic pulmonary infection, or any systemic disease that primarily affects the lungs. History of any pulmonary nodule will be excluded to participate in the study,
15. Active smokers,
16. Marijuana users,
17. Insulin pump users,
18. Using insulin detemir or NPH as basal insulin, and
19. Any other condition, as determined by the investigator, which could make the subject unsuitable for the trial, impairs the subject's suitability for the trial, or impairs the validity of the informed consent -
