The Commission of Inquiry

Seen from above, Copenhagen in late autumn 1953 appears orderly: the harbor moves with commercial traffic, bicycles flow along the lanes, and the hospitals have resumed their appointed functions. The polio wards stand emptied, and the students have returned to their lecture halls. Yet inside one building on the edge of the old city, a commission has convened to examine what happened during the epidemic year and to decide whether the extraordinary measures of that time could be transformed into a permanent practice. The question that would shape the new system was whether the urgency of the emergency period could be preserved once the emergency itself had passed.

The commission meets in a room on the third floor of a government building near the Rigshospitalet. The windows overlook a courtyard where leaves have gathered in drifts against the walls. Inside, a long table has been arranged in a U-shape, with places for seven commissioners, a secretary, and the witnesses who will appear over the coming months.

The binders begin to accumulate from the first day: case reports, duty rosters, supply requisitions, mortality statistics, the handwritten logs of the student shifts. The chairman is a senior physician from the University of Copenhagen, appointed for his administrative experience rather than any involvement in the epidemic. He opens the first session by reading the formal charge. The commission is to investigate the management of the 1952 polio epidemic, Denmark’s worst outbreak in its history, with particular attention to the respiratory care of bulbar patients, the deployment of medical and dental students as manual ventilators, and the expenditure of public resources on an improvised system of continuous positive-pressure ventilation through tracheostomy.

The language is careful, bureaucratic, designed to contain within recognizable categories what had in fact burst every category. The chairman sets down his document. The secretary prepares her pen. The first witness is called.

Bjørn Ibsen enters the room on a November morning. He is forty-two, an anaesthetist by training, and he carries with him the authority of a man who has spent the past fifteen months defending a decision made in the middle of a night. His testimony will extend over three full days.

The commissioners ask him to begin at the beginning: his arrival at Blegdam on August 27, 1952, his examination of the twelve-year-old girl whose carbon-dioxide retention he detected, his insistence that she be subjected to a tracheostomy and manual ventilation despite the opposition of the senior consultant. Ibsen speaks calmly, methodically, reconstructing the physiological reasoning that led him to reject the established diagnosis of polio virus as the direct cause of death in these patients. He explains the blood-gas measurements that Poul Astrup had developed, the pH readings that revealed the true state of the patients’ acid-base balance, the way these numbers translated into a new understanding of respiratory failure.

The commissioners interrupt with questions. They want to know why he acted without consulting the hospital’s administrative authority. They want to know whether he understood, at the time, that he was committing the institution to an open-ended expenditure of labor and material. Ibsen answers that he understood the immediate choice perfectly: the girl would die without intervention, and die within hours. The larger consequences unfolded only afterward, as the method proved applicable to patient after patient.

He does not apologize. He does not claim foresight. He presents himself as a physician who saw what was in front of him and acted accordingly.

The next day, the questioning turns to the students. The commissioners have before them the duty rosters from August and September 1952, the handwritten lists that name more than fifteen hundred medical and dental students who worked in shifts around the clock. They have calculated the hours: approximately two million manual ventilations delivered by hand, each requiring four seconds of compression and release, each demanding continuous attention to the resistance of the bag and the rise of the chest.

They ask Ibsen how he justified this use of human labor. He replies that the labor was available, that the students volunteered, that no machine then existed that could perform the function. The commissioners press further. They want to know whether this was medicine or desperation. They want to know whether a system that required such expenditure could be considered a legitimate treatment or merely an emergency expedient.

Ibsen distinguishes between the method and its temporary implementation. Positive-pressure ventilation through tracheostomy, he argues, is physiologically sound and permanently applicable. The reliance on manual compression was a constraint of the moment, to be replaced by mechanical devices as these became available. The commissioners make notes. Their faces reveal nothing.

Poul Astrup appears before the commission in December. He is younger than Ibsen, a medical registrar who has spent the intervening year consolidating his blood-gas methodology into a standard laboratory technique.

His testimony centers on the measurements themselves: the arterial samples drawn from patients at various stages of respiratory failure, the pH and carbon-dioxide tension values that demonstrated the inadequacy of negative-pressure ventilation, the serial readings that tracked the effectiveness of manual positive pressure. The commissioners have studied his published papers. They ask him to explain why these measurements had not been available earlier, why Danish hospitals had operated for decades without access to such basic physiological data. Astrup explains the technical difficulties: the need for anaerobic sampling, the precise temperature control, the electrical equipment that his laboratory had to assemble from components. He acknowledges that the method was primitive by later standards. He insists that it was sufficient to establish the facts that mattered.

The commissioners ask him to project forward. If blood-gas analysis becomes routine, what does this mean for the organization of hospital care? Astrup replies that it means continuous monitoring, specialized nursing, the concentration of respiratory patients in dedicated units where expertise and equipment can be concentrated. He describes a system that does not yet exist, that has no name in Danish medical administration, that will require resources and personnel that no hospital currently possesses. The commissioners write down his words. They do not commit themselves.

Henrik Lassen testifies in January 1954. As the medical registrar who compiled the definitive case series on the epidemic, he brings numbers that the commission has requested: 2, 722 patients admitted to Blegdam Hospital with polio between July and December 1952; 316 with bulbar involvement requiring respiratory support; 191 treated with tracheostomy and manual ventilation; mortality in this group reduced from an expected 80-90 percent to 40 percent in the acute phase, and to 11 percent at one month. The commissioners have prepared their own calculations. They ask Lassen to account for the discrepancy between patients treated and patients saved. If manual ventilation reduced mortality so dramatically, why did 76 of the 191 still die? Lassen explains the complications: secondary infection, cardiac failure, the delayed recognition of respiratory insufficiency in patients whose bulbar symptoms developed after admission. He does not claim more for the method than it achieved.

The commissioners then turn to the cost. They have estimated the student hours, the tracheostomy tubes consumed, the antibiotics deployed against pneumonia, the additional nursing staff required for the round-the-clock surveillance of intubated patients. They ask Lassen whether any hospital in ordinary circumstances could sustain such expenditure. He replies that ordinary circumstances had not obtained, that the epidemic represented a temporary emergency that justified extraordinary measures. The commissioners ask whether the emergency has now passed, and what justification remains for preserving the system it created. Lassen has no answer that satisfies them. He can only point to the survivors.

The senior administrators of Blegdam Hospital appear in February. Their testimony is defensive, carefully prepared with legal counsel.

They describe the chaos of late August 1952: fifty paralytic patients arriving in a single day, the single Emerson iron lung and six cuirass respirators completely inadequate, the wards transformed into improvised intensive care units without authorization or precedent. They acknowledge that they did not prevent Ibsen’s intervention on August 27. They explain that they did not understand its implications until the following days, when the demand for manual ventilation expanded beyond any possibility of recall. They present themselves as administrators who inherited a situation rather than created it, who managed catastrophe as best they could, who now seek guidance on how to prevent such improvisation in the future.

The commissioners question them closely on the chain of command. Who authorized the tracheostomies? Who determined the criteria for admission to manual ventilation? Who bore responsibility when students, exhausted after hours of squeezing, made errors in judgment or technique? The administrators reply that responsibility was distributed, that the emergency required decentralized decision-making, that the traditional hierarchy of the hospital was temporarily suspended. The commissioners note this admission. They ask whether such suspension can ever be legitimate. The administrators have no ready answer.

The students appear in March. Not all of them, of course—the commission hears testimony from a selected dozen, representing the medical and dental faculties, the various years of study, the different wards where they worked.

Their accounts are raw where the physicians’ testimony was polished, fragmented where the administrators’ was coherent. One describes the physical experience: the ache in the thumbs and wrists, the tremor that developed after the first hour, the necessity of shifting grip without interrupting the rhythm of ventilation. Another speaks of the psychological experience: the intimacy of holding another person’s breath in one’s hands, the terror of feeling the bag suddenly resist as a patient coughed or bucked, the relief of the arriving shift, the inability to sleep afterward despite exhaustion. A third testifies to what was learned: the anatomy of the airway, the signs of adequate versus inadequate ventilation, the recognition of impending death. Several state that they would not have traded the experience, that it formed them as physicians more profoundly than any lecture or laboratory exercise. Others describe nightmares, persistent anxiety, a changed relationship to their chosen profession.

The commissioners listen without visible reaction. They have been charged with evaluating a medical intervention, not a moral education. Yet the students’ testimony introduces something that the official documents cannot contain: the system of manual ventilation was a social arrangement, a temporary community organized around the most basic of physiological functions, and that community possessed qualities no mechanical replacement could replicate.

The commission’s deliberations extend through April. The commissioners meet in closed session, reviewing the accumulated testimony, debating the categories into which the Blegdam experience can be fitted.

They recognize that they face a fundamental problem of classification. The manual ventilation system was not, by any standard definition, a legitimate medical treatment when it was introduced. It had no authorization from the hospital’s medical committee, no basis in published literature, no precedent in Danish or international practice. Yet it worked. The mortality figures, however disputed in their precise interpretation, demonstrated a dramatic improvement over any alternative then available.

The commissioners must decide whether effectiveness alone can legitimate innovation, or whether the forms of medical authority must be respected even at the cost of lives. They must decide whether the student labor force represented an exploitation of vulnerable young people or a remarkable demonstration of professional solidarity. They must decide whether the expenditure of public resources on an improvised, unrepeatable system can be justified by its results, or whether such expenditure establishes a dangerous precedent for future emergencies.

Their debates turn repeatedly to the question of permanence. The emergency that produced manual ventilation has ended. The polio wards have emptied. The students have returned to their studies. Yet the method itself—positive-pressure ventilation through tracheostomy, with continuous monitoring of blood gases—has been established as physiologically superior to the negative-pressure devices that preceded it.

The Engström respirator, developed in Sweden and tested in the 1953 epidemic there, offers a mechanical means of delivering the same intervention without the exhausting, error-prone reliance on human hands. The commissioners receive technical briefings on this device. They learn that it reduces the mortality in bulbar patients from 90 percent to 20 percent, matching or exceeding the results of manual ventilation with far less labor. They understand that the future lies with such machines, not with the improvised human system of 1952.

Yet they also understand that the machines require the same organizational infrastructure: the concentrated expertise, the continuous monitoring, the specialized nursing, the blood-gas laboratory. The question is no longer whether to preserve manual ventilation. The question is whether to preserve the system that made manual ventilation possible, and to give it a permanent institutional form.

The commission’s report is completed in May 1954. It runs to 187 pages, with appendices containing the statistical tables, the duty rosters, the blood-gas measurements, the cost calculations.

The commissioners have decided to legitimate the innovation while condemning its improvisation. They find that positive-pressure ventilation through tracheostomy represents a valid therapeutic advance, that its development during the epidemic was justified by the emergency circumstances, and that its continued application should be supported with appropriate resources and personnel. They find that the deployment of students as manual ventilators was an emergency expedient that cannot be repeated, that it exposed both patients and students to unacceptable risks, and that it should be replaced by mechanical ventilation at the earliest opportunity.

They recommend the establishment of a permanent respiratory unit at Blegdam Hospital, with dedicated staff, specialized equipment, and formal protocols for the management of respiratory failure. They do not assign individual blame for the improvisations of 1952. They do not credit individual achievement for its successes. The report is signed by all seven commissioners and submitted to the Ministry of Health.

The ministry’s response comes in June. The recommendations are accepted in principle. Funding is authorized for the conversion of existing ward space at Blegdam Hospital into a dedicated respiratory unit, for the purchase of Engström respirators and associated equipment, for the training of specialized nursing staff. The ministry adds conditions. The new unit will operate under formal administrative authority, with clear lines of responsibility and regular reporting requirements. The use of students in any clinical capacity will be strictly regulated, limited to observation and supervised practice, excluded from life-sustaining interventions. The blood-gas laboratory will be expanded and standardized, with results subject to routine quality control. The innovations of the epidemic year are thus incorporated into the structure of Danish hospital administration, stripped of their improvisational character, fitted into categories of legitimate medical practice.

Ibsen reads the commission’s report in his office at the Rigshospitalet. He has been appointed chief of the new respiratory unit, a recognition that the commissioners could not withhold even as they criticized his methods. The report’s language irritates him: the careful balance between approval and caution, the insistence on formal authorization, the implicit suggestion that the lives saved in 1952 were saved despite rather than because of the system’s improvisational character. Yet he recognizes that the commission has given him what he needs. The unit will exist. The methods will continue. The students will be replaced by machines, but the fundamental principle—continuous, monitored, positive-pressure support for failing respiration—will be preserved. He begins to plan the physical layout of the new department, the arrangement of beds and equipment, the flow of personnel and information. The emergency has been transformed into architecture.

Astrup reads the report in his laboratory. The commission has endorsed blood-gas analysis as a standard diagnostic tool, has recommended its expansion throughout the hospital system, has recognized his own contribution with a formal citation. He is pleased, but he is also aware of what has been lost. The measurements he developed during the epidemic were intimate, immediate, connected to the clinical moment by the shortest possible thread. The technician drew the arterial sample, ran it through the apparatus, brought the result to the bedside within minutes.

The new system will be more reliable, more reproducible, more suitable for scientific publication. It will also be slower, more bureaucratic, more removed from the physician’s direct perception of the patient. Astrup understands this trade-off. He accepts it as the price of permanence. He begins to design the quality-control protocols that the ministry has required, the standardized procedures that will make his method reproducible across institutions and investigators.

Lassen reads the report in the medical library, surrounded by the files from which he constructed his case series. The commission has accepted his mortality figures, has cited his work as the evidentiary foundation for its recommendations, has acknowledged the statistical demonstration that manual ventilation saved lives. Yet the report also contains a subtle dismissal of the knowledge he produced. His case series was retrospective, compiled from records that were themselves improvised, subject to the gaps and inconsistencies of emergency documentation. The commission calls for prospective studies, controlled trials, standardized data collection. Lassen understands the scientific logic. He also understands that the knowledge he gathered was produced under conditions that cannot be replicated, that the precision of future research will be purchased at the cost of a clinical truth that only those improvised months could yield. He files his papers and turns to new projects.

The students read the report, those few who bother, in their continuing studies or their early practices. The commission mentions them only briefly, as an emergency resource that served its purpose and must not be repeated. Their individual experiences, their testimonies about the physical and psychological costs of manual ventilation, appear in the report as anonymous data points. The commission has not understood, or has chosen not to acknowledge, that the student labor force was a social form with its own characteristics: the collective responsibility, the shared exhaustion, the immediate feedback between effort and outcome. The students move into their professional lives. Some become anaesthetists, carrying forward the techniques they learned at the bedside. Others choose different specialties, leaving behind the memory of those months. A few, troubled by their experience, abandon medicine entirely. Their names do not appear in the official record.

The commission’s work concludes in June 1954. The room on the third floor is cleared, the binders transferred to archives, the secretary reassigned. The courtyard outside has changed with the season, the drifts of leaves replaced by early growth on the chestnut trees. The commissioners return to their ordinary responsibilities, their brief moment of institutional judgment complete. What they were charged to do has been accomplished: to examine the extraordinary events of 1952, to render them comprehensible within the categories of bureaucratic medicine, to extract from improvisation a set of principles that can guide future practice. The fundamental tension that the epidemic revealed has not been resolved. It has only been formalized.

The inquiry’s findings provide a mandate. The paper approval exists, signed and stamped, authorized by the appropriate ministries. What remains is to translate that approval into walls and wires, into a department that will outlast the memory of its origin, into a form of medical care that will be called intensive care before it has any name at all. The commissioners have judged the past. The architects must now build the future.
