I lost my daughter to 'natural causes', pneumonia from cancer treatment. It was horrible. Her lungs failed after weeks of battling two infections and leaked the air they were unable to exchange, whilst she was on a vent. The poor doctor was so, so kind. We asked what would happen if the vent were not turned off. He told us the truth, and I've learned from other doctor friends that it was indeed the truth. Those patients wake up, no matter how heavily sedated, as the build up of air literally crushes them to death from the inside and finally their hearts cease to beat due to pressure. And he said, very softly, 'It haunts me.' We had no wish to visit that on her nor that man, who was very kind, nor anyone else. We switched her off. Other people chose differently, that is their choice.
We have since come to know countless other bereaved parents whose children died of other natural causes and the stories I can tell you would make a statue keen with grief.
Despite all the best palliative care, it is not drifting off to sleep much of the time. The human body clings and fights for life.
Death is not pretty or romantic. Changes happen very quickly to the body.
As an adult, I would seek to avoid this if possible, and I resent others dictating what they think it best for me because it doesn't sit well with their comfort zone and their parameters.
I do not judge others who opt differently but that is just it, it should be a choice, and I do resent others who think I, or anyone else, should not have that option, to die with as much dignity as possible, with loved ones who chose to be there, and treat me and those people like criminals.
