My Mothers Life is in Jeopardy. Please help Us.

Hello. I will try and be as descriptive as possible.
My mother is 66 years Old. Overweight Woman. She was diagnosed with Lung Cancer 3 years ago (Life long smoker. Quit 3 years ago)
She had a Wedge resection done of the Lung to treat. Chemo (2 years ago) and this year 2 Cryo Ablations done. Same Lung for all 3 events.
She has GERD and Gastritis

Her medications. Famotidine, Dycyclomine, Trelegy, Triceba, Mounjaro, Prednisone, Albuterol

My mother has been to nearly every doctor we could find for this and are receiving no answers for whats going on. We are hoping someone in this big world has seen this or experienced this before.

She has had 2 major life threatening events.
Patterns we have taken notice of prior to these events.
She becomes short of breath days before and takes multiple treatments of Albuterol Inhaler, Nebulizer and Prednisone.
It happens after she wakes up and goes to the bathroom to relieve herself. And it never happens when she is in the Hospital

She has her bipap on. Shes short of breath. Goes to bathroom. Sits down to sleep. Becomes tight in the chest, her breathing becomes shallow. Eventually she stops breathing all together. Her eyes are wide open but they're lifeless. Like no one is in there. Her teeth lock up and are clenched. She turns ice cold and blue in the lips. It looks like she is dying

We get her to the floor, perform CPR On her till Ambulance arrives. During CPR her hands and feet start moving and her eyes a little. Like shes coming back but not fully. Ambulance comes and puts her on Oxygen immediately, her Oxygen is at 80, they say she is unresponsive but eventually she comes back. Her Sugar is over 300, her blood pressure is over 200. She is also extremely bloated as well. Her stomach was like 3x its regular size

They take her to the Emergency Room. By the time she gets to the emergency room, she returns to absolutely normal. Almost as if nothing has happened to her all together. Even though if no one arrives she would no longer be here with us.

They start doing their testing on her. Catscans, EKGs, Blood Work. They show no sign of tissue damage or heart attack, Lungs come out fine and no issues with the lungs. Her blood work shows nothing happened and she never lost oyxgen. They say if she had lost oxygen for 5 minutes she would be dead or on a respiratory and she is not. By the time she gets to Hospital they see no evidence anything happened at all. Even though several of us clearly see what looks like she is suffocating and slowly dying.

They throw theories out at us, all these doctors have different theories but none are bearing any fruit.

Theory 1. Vasalvago. However I read thats fainting, and what she is doing is not fainting at all.

Theory 2. Bronchospasm. However it says Bronchiodiolaters would remedy this and she was using Inhalers and Nebulizer

Theory 3. Sleep Apnea but she sleeps with a Bipap on her face.

Theory 4. She has reflux of the stomach and is triggering a spasm of her esophagus (but Hospital says her throat is fine and cant see it closed )

Theory 5. Her reflux is pushing up food and the bipap is pushing it back down (even though last thing she ate was a turkey sandwich 12 hours before, however she did go right to sleep after eating it and complained she had indigestion and nausea. And burping very loudly

The only thing the Hospital found is that she is backed up in her intestines with feces and not taking large bowel movements. Shes constipated and they think maybe the constipation or her compressing her abdomen is putting pressure on her diaphram.

Other than that. No signs of anything. No covid, no infections, no pneumonia. They cannot see anything and ultimately send her back home to us. And then we live in fear it will happen again or ultimately take her from us.

Please. I am begging you. Someone has to have seen this before happen or know what is going on with her. We took her everywhere in New York we could find and they just tell us we don't see anything.

Thank you, for all the work you do.
