BBM Iam glad you commented on this! I was hoping you would.
I had lots of questions too.
what is the length of the flight from California to New York?
Well, a commercial flight is about 4-5 hours. In a small jet, I suspect they would have to stop for gas at least once, maybe twice, depending on the route, the altitude, and the particular jet. (I am not a pilot.) And assuming they didn't have to follow a convoluted flight plan due to weather or other administrative reasons.
How much duplicate machinery/back up supplies would be required for the flight?
Hard to answer. I don't know what their capabilities are, and what they use for an oxygen source. For example, if you are "hand bagging" a vent patient during transport on or off, or during time on the ground, you use much more oxygen than the vent uses. Most vents are pretty efficient. But you have to plan for emergencies, delays, etc.
An air ambulance will have their own cardiac monitors, pulse ox, ETCO2, IV pumps, suction, and bags of fluids and other supplies. Transport ventilator, too. They will have back up ETT's and laryngoscopes.
A big risk in transport for Jahi's body would be dislodging the ETT. Who knows if the crew and the doc in attendance are skilled at placing another ETT in a reasonably complex situation, in a patient with an ETT sitting there with the cuff eroding her trachea for the past 3 weeks?
How many people would need to be on board in the event of an emergency with Jahi?
I don't know how big their plane is. Probably at least 2 individuals to care for the patient.
what if the doctor had a health emergency who would back him up?
The flight nurses. We almost never had a doc fly with us when I was doing military airevac. And if we did, they were pretty out of their element, and generally not a lot of help.
what if for some unforeseen reason she had to be manually ventilated? How long could one person do it alone?
Until they collapsed of exhaustion, I suppose. If the oxygen ran out, they can bag someone with room air. I had to do that once for about 2 hours till we landed. (I had help and med techs to squeeze the bag-- these were military aircraft.) I had a couple missions where the vents weren't working well and we switched to hand bagging for a period of time.
What effect would the ascent/descent and altitude have on her brain pressure, blood pressure and /or other bodily functions?
From what I know of her situation, I can't see any reason for an altitude restriction. The cabin of most aircraft is pressurized at about 8000ft. The most serious affects on physiology happen in the first 5000 feet ascending. When someone has something like a pneumothorax (an air pocket in the space between the pleura and the lung), it's important to have a chest tube in it, because as the aircraft ascends, the air will expand, and collapse the lung. (Think of potato chip bags inflating on commercial flights-- any gas pockets in the body will expand, such as the colon.) The cuffs of ETT's can be filled with saline, instead of air, to reduce the potential for the cuff bursting or causing more tracheal trauma. I don't know if she has a ventriculostomy, but her brain is already dead, so air expansion intracranially is kind of a non-issue.
I have no idea what effects acsent would have on her body's blood pressure, since I don't know how her body is behaving now. I have transported dead bodies, but we weren't trying to keep them alive anymore. I had one pt die past the j-point on the way to Hickam (too far to turn around or divert), who was a DNR, but wasn't on a vent. Family was trying to get him back to the US before he died. We covered him with a blanket, and he was "officially" pronounced dead on the ground in HI. You can't call an inflight emergency for a DNR who dies. Interestingly, you can be born in flight-- birth cert shows longitude and latitude. But you cannot "die" in mid air. But I digress...sorry.
What about autonomic dysreflexia. I know she is brain dead but can she have problems like quadriplegics do?
Yes. Those reactions are mediated by the spinal cord independently of brain function.
Will ventilator settings need to be tweaked during takeoff and landing?
Probably. Depends on what the goals for therapy are. Are we going for a certain set of vital signs, O2 sat, ETCO2? How aggressively are we going to treat anything? BP, heart rhythms, etc. Do we do CPR if her heart arrests? Use electricity? Drugs?
*I just don't see this plane ever leaving the ground.
I agree.
Who would be held responsible if her heart stops beating on its own during the flight?
God? IDK. I really have no idea of the legal ramifications of caring for and transporting a person declared dead.
