The goal of this clinical research study is to learn whether using early non-invasive
positive pressure ventilation (NIPPV), a method of delivering oxygen using a mask, or high
flow oxygen (using a tube with 2 prongs placed in the nostrils) is better at improving the
amount of oxygen in your blood, reducing shortness of breath, and the need for intubation
(placement of a tube in the windpipe) in patients with blood cancer and hypoxemia.
If you agree to take part in this study, you will be randomly assigned (as in the flip of a
coin) to 1 of 2 groups. This is done because no one knows if one study group is better, the
same, or worse than the other group. You will have an equal chance of being in either group:
- If you are in Group 1, you will receive high flow oxygen through your nose.
- If you are in Group 2, you will receive oxygen through a mask (NIPPV). You will also
receive high flow oxygen through your nose, if the doctor thinks it is needed
Before you begin treatment and then every 4 hours while you are in the hospital, the study
staff will visit you. At these times, you will have a brief physical exam. This will include
a check on how well you are breathing, how alert you are, and to measure your oxygen levels.
These visits will continue until your hypoxemia improves enough where you no longer need
If your condition worsens and you are in Group 1 and the study doctor thinks it is in your
best interest, you will be allowed to receive oxygen through a NIPPV mask. If you are in
Group 2 and your condition improves or you do not want to wear the mask anymore, you will be
allowed to receive oxygen through your nose.
The study staff will follow your progress by reviewing your medical chart for up to 28 days
after you started the study or until you leave the hospital (whichever comes first). During
this time, the study staff may visit you to learn how well you are tolerating treatment.
Length of Study:
Your participation in this study will be over after 28 days or when you leave the hospital.
Researchers will continue to collect information regarding your health from your medical
records for up to 100 days.
