I recently had a man with broken ribs as a patient, he told us he usually has CPAP overnight, and brought his machine and mask in. I was on night shift, and when I assisted him with the setup it was clear that the mask and harness had about four flaws that destroyed the seal. I'd McGyver the thing with tape and something else would give. It was unusable.
i called RT to obtain a mask for him to use temporarily, and the tech said they don't have any. Well, yeah they do...we use hospital CPAP on CHF patients routinely. Then he said the hospital mask is not compatible with the patient's machine. I didn't think anyone could say that without actually looking at the patient's machine, so I asked the RT to come to the unit, with the mask, please. He refused to bring a mask, but he came, took one look, and said the hospital mask couldn't be used.
The RT says that each machine must be paired with a mask specifically designed for a particular machine. He said by using one of the hospital masks with an outpatient machine, the air flow wouldn't be correct, and we would risk patients dying of co2 toxicity. I've thought about this since....I think the CO2 toxicity issue is bogus. Those masks must hold less than 50ml of air, and it's air that's constantly flowing with the pressure. Even without the machine turned on, tidal volume is what, 500ml? It just doesn't jive for me.
Second, the issue of needing a specific mask with each make of CPAP machine. Also doesn't ring true. The machine and the mask don't communicate with each other. Every machine will generate the required air pressure, and if a mask has more or less ventilation the pressure will be maintained. If a mask has safe airflow with one machine, what changes to make it unsafe with another machine?
If anyone has information that supports or negates what I've said, could you let me know?
i'm thinking that this is all about which department has to pay for the equipment.
