In the Midst of Life

stranger who had walked in by mistake.
    This is what most of us can expect, unless we are very lucky. If anyone collapses, from whatever cause, at home or in a public place, the chances are that they will be taken to hospital. Only the medical team involved knows what goes on in the resuscitation room of a hospital, because lay people are excluded. When my mother died, I was pushed out and the doors were locked on the inside. There may be good reason for this, such as the risk of introducing infection into the room, but I suspect it is more because a relative may try to stop what is going on.
    Sherwin B Nuland was a consultant surgeon at Yale University Hospital and teaches surgery and the history of medicine at Yale. In his remarkable book,
How We Die,
published in 1995, he has described the process of hospital resuscitation as accurately and objectively as any medical man can for the lay readership:
    Having countless times watched those teams fighting their furious skirmishes, and having often been a participant or their leader in years past, I can testify to the paradoxical partnering of human grief and grim clinical determination to win that actuates the urgencies swarming through the mind of every impassioned combatant. The tumultuous commotion of the whole reflects more than the sum of its parts, and yet the frenzied work gets done and sometimes even succeeds.
As chaotic as they may appear, all resuscitations follow the same basic pattern. The patient, almost invariably unconscious because of inadequate blood flow to the brain, is quickly surrounded by a team whose mission is to pull him back from the edge by stopping his fibrillation or reversing his pulmonary oedema, or both. A breathing tube is rapidly thrust through his mouth and down into his windpipe so that oxygen under pressure can be forced in to expand his rapidly flooding lungs. If he is in fibrillation, large metal paddles areplaced on his chest and a blast of 200 joules * is fired through his heart in an attempt to stop the impotent squirming, with the expectation that a regular beat will return, as it frequently does.
If no effective beat appears, a member of the team begins a rhythmic compression of the heart by forcing the heel of his hand down into the lowest part of the breastbone at a rate of about one stroke per second. By squeezing the ventricles between the flatness of the yielding breastbone in front and the spinal column in the back, blood is forced out into the circulatory system to keep the brain and other vital organs alive. When this form of external cardiac massage is effective, a pulse can be felt as far away as the neck and groin. Although one might think otherwise, massage through an intact chest results in far better outcomes than does direct manual compression.
By this point, IVs [intra-venous drips] will have been inserted for the infusion of cardiac drugs, and wider plastic tubes called central lines are being expeditiously inserted into major veins. The various drugs inserted into the IV tubing have assorted purposes: They help to control rhythm, decrease the irritability of the myocardium, strengthen the force of its contraction, and drive excess fluid out of the lungs, to be excreted by the kidney. Every resuscitation is different. Though the general pattern is similar, every sequence, every response to massage and drugs, every heart’s willingness to come back – all are different. The only certainty, whether spoken or not, is that the doctors, nurses and technicians are fighting not only death but their own uncertainties as well. In most resuscitations, those uncertainties can be narrowed down to two main questions: Are we doing the right things? And should we be doing anything at all?
Fartoo often, nothing helps. Even when the correct answer to both questions is an emphatic ‘yes’, the fibrillation may be beyond correction, the myocardium unresponsive to the drugs, the increasingly flabby heart resistant to massage, and then the bottom falls out of the rescue attempt. When the brain has been starved of oxygen for longer than the critical two to four minutes, its injury becomes irreversible.
Actually, few people survive cardiac arrest, and even fewer among those seriously ill people who experience it in the hospital itself. Only about 15 per cent of hospitalised patients below the age of seventy and almost none of those who are older can be expected to be discharged alive, even if the CPR team somehow manages to
