Close monitoring, both of clinical parameters and of arterial blood gas values is of paramount importance. If the patient still feels dyspnoeic, irrespective of his other clinical parameters, he should be closely watched, and an arterial blood gas should be performed. If the blood gas analysis shows worsening hypoxaemia and normocapnoea or hypercapnoea with respiratory acidosis in spite of maximum medical therapy, ventilation should be considered before the patient develops respiratory arrest. The outcome is much better if the patient is electively ventilated than if he is ventilated after an arrest. Ventilation Mechanical ventilation should be considered if at least two of the following are present: x At least moderate dyspnoea, with use of accessory muscles and paradoxical abdominal motion x Hypercapnic acidosis (pH <7. In intubating the patient, the largest possible endotracheal tube should be used, both to reduce airway resistance and to enable easy suctioning of secretions. Antibiotic therapy Most exacerbations of asthma are non-infective, and antibiotics have no place. The eosinophil count in sputum in asthma is high, hence the sputum maybe yellow in the absence of infection. An antibioitic which is effective against Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis, and atypical bacteria should be used. Severe hyperinflation of the chest can result in reduced venous return and decreased cardiac output. Severe acidosis and hypoxia can decrease myocardial contractility and reduce cardiac output. Long term management Once the patient has improved, long term therapy with inhaled steroids, long acting bronchodilators, pulmonary rehabilitation and immunization should be planned. The pressure at the venous end of the pulmonary capillaries (measured as the pulmonary capillary wedge pressure) is normal. Respiratory Failure 98 Handbook of Critical Care Medicine x The wet heavy lung causes basal atelectasis. Dyspnoea occurs due to increased work of breathing in an attempt to compensate for impaired gas exchange and shunting. The patient may give a history of chest pain, and may have a past history of ischaemic heart disease or heart failure, or valvular heart disease. Fluid nd rd overload after surgery occurs around the 2 to 3 postoperative day, and results from progressively increasing positive fluid balance. Fluid overload due to acute renal failure is similar, and the patient will be oliguric, with elevated blood urea and serum creatinine. Treatment is largely supportive, and is aimed at improving oxygenation and preventing ventilator induced lung injury. If the hypoxaemia does not resolve (as often it does not), intubation and ventilation is required. It is better to ventilate early before the patient develops severe hypoxaemia or Respiratory Failure 100 Handbook of Critical Care Medicine exhaustion, which can result in cardiovascular instability and possible cardiac arrest. Assist control ventilation or Synchronised intermittent mandatory ventilation may be used. Whatever method is used, the following principles should be adhered to; Low tidal volume ventilation: a tidal volume of 6ml/kg body weight significantly reduces mortality compared to higher tidal volumes. High oxygen concentrations2 damage the alveoli, and may worsen alveolar collapse, as oxygen is absorbed very quickly from the alveoli. Treating infection Appropriate antibiotics should be used to treat pneumonia, if it is the primary cause. Choice of appropriate antibiotics is discussed in the section on severe infection. Fluid management Careful fluid management is important, to avoid overhydration and fluid overload, while maintaining adequate cardiac filling pressures. Steroids are of proven benefit in patients with acute respiratory failure due to Pneumocystis carinii pneumonia, tuberculosis and vasculitis. Prone position ventilation Turning the patient over is one way of redistributing blood flow within the lung and recruiting underventilated and collapsed alveoli. While there is little evidence that it improves survival, the method is useful to improve oxygenation. Complications of ventilatory support Ventilator induced lung injury Pneumothorax is the most well known complications of ventilation, with an incidence of 10%. Mediastinal, retroperitoneal, peritoneal or subcutaneous emphysema can also occur. Pneumothorax may require emergency aspiration, especially in the case of a tension pneumothorax, or an intercostals drainage tube. Always suspect pneumothorax if the patients respiratory parameters deteriorate suddenly. Microscopic lung injury Opening and closing of alveoli and overdistension of alveoli result in damage to the alveoli. This can trigger a local inflammatory reaction, which can become generalised and result in multiorgan dysfunction. Bacteria can spread across the damaged alveoli to the bloodstream, worsening sepsis. Oxygen induced injury Respiratory Failure 102 Handbook of Critical Care Medicine High concentrations of oxygen are toxic to the lungs. High concentrations of oxygen cause alveolar collapse, as oxygen is absorbed rapidly. Respiratory Failure 103 Handbook of Critical Care Medicine Mechanical ventilation Mechanical ventilation is often required in critically ill patients who develop respiratory failure. While it is a valuable tool to assist ventilation, it can be dangerous if used inaccurately or unnecessarily.

Sudden changes can occur—intellectual history reveals the suddenness of some transform ations generic forxiga 10mg. Sufficient weight is now accumulat­ ing; a shift in social and political vision is coming discount forxiga 10mg on-line. T he “trans­ form ation forxiga 10 mg on line,” to use George Leonard’s w ord,1 is based in a sharp alteration in our image o f reality. Leonard suggests that the shifts in W estern scientific thought outlined in Thom as K uhn’s The Structure of Scientific Revolutions2 yield clues to what is occurring. Even up to the point where the paradigm breaks down, phenom ena m ust either fit or be shoved into the paradigm as they are discovered. But new paradigm s can em erge from the old when the explanatory power of the old is exhausted. Leonard describes some of the boundary conditions for change: An Emerging Zeitgeist 143 T h e new p aradigm ap p ears and prevails only if the old o n e is in a state o f crisis, only w hen the o ld er m ode o f investigation seem s to be p ro d u cin g a series o f anom alies and is ru n n in g into increasing difficulties w ith certain key questions o f the tim es. But for all of his effusiveness, his vision lacks the analytic rigor necessary to convert the hardhearted. Such groups, w hen they are able to coalesce th ro u g h an u n d e rstan d in g o f th eir relatedness to one a n o th e r and to the n atu ral processes involved in “N atu re’s gam e” o f survival an d evolution, will find stren g th a n d co u rag e in sensing them selves as a p a rt o f the C osm os and as being involved in a gam e that is in accord w ith N atu re and not an ti-natural. T hese g ro u p s will initiate m ovem ents, w hich in tu rn will be m anifest in th eir effect not only u p o n the species and th e planet but u p o n individual lives. T h e ir benefit is likely to be expressed in a g re ater satisfaction an d fulfillm ent in life. His book is a biological counterpart to a dialogue begun by ecologists such as Barry Com m oner and G arrett H ardin, quantitative scien­ tists such as Meadows and the members of the Club of Rome, and social philosophers such as Ivan Illich and George Leonard. But Salk’s work is unique because, o f those 144 T he Climate for Medicine who have argued that growth must be limited, only he has also offered an argum ent that man is equal to the task. In nature all animals, including hum an beings, survive on the basis of principles of natural selection. N ature “chooses” from a “blooming profu­ sion” of choices those life forms with survival value. One species of moth survives because a random m utation in the coloration of its wings happily blends into the field of flora in which it lives; another is decimated by predators because its wing color­ ation contrasts rather than merges with the backdrop. His reasoning runs som ething like this: If there are unmistak­ able signs of decay in our culture—the population explosion (upon which he relies heavily), environm ental degrada­ tion, wide-ranging mental instability, endless war and conflict—then for that culture to survive, it must evolve. In short, according to Salk, it must reestablish a harmonious relationship with its surroundings. But this can only take place through natural selection; nature will judge us for our survival value. Salk argues that we must therefore create and then share ideas that have survival value. What is novel about Salk’s thinking is that it can now be made public by such a distinguished scientist and scholar. Those who argue that hu­ An Emerging Zeitgeist 145 manity has reached an epoch break, a point of transition to a new era and a new humanity, are not lonely voices in the wilderness but part of a growing chorus. T he first, which foresees the end of civilization, the dissolution of culture, is well represented by Lewis M um ford in The Myth of the Machine, by William Irwin Thom pson in At the Edge of History and Passages About Earth, and by George Leonard. Some o f these commentators, such as Leonard, have gone on to the second argum ent—that a new epoch is em erging, or at least that we are on its threshold. It has become less and less easy to dismiss these voices as millenarian, rustic, nonscientific, or even crazy. Sociocultural innovation is impoverished, and economic and political structures are variations on a common and empty theme. Revolutions and revolts, each chasing on the heels o f its predecessor, disap­ pear one into another in a dreary uniform ity—the op­ pressed become the oppressors, and so on. In The Struggle Against History, Ronald Segal, a socialist critic and writer, recognizes this when he says of the two dom inant political and economic systems: “While the two. Remedial pro­ grams utilizing still m ore technology are ultimately self- defeating. Moreover, there may be fixed and im m u­ table limits to growth, even though we do not know when we shall reach them. Robert Theobald puts it this way in Habit and Habitat: 146 The Climate for Medicine All o th er species w ork w ithin th e existing habitat. T h e ir success o r failure d ep en d s u p o n th eir ability to ad ap t to th e conditions in w hich they find them selves.

H e has d e­ veloped th e habit o f seeing his habitat as totally flexible accord­ ing to his ow n wishes and desires. Prevailing paradigm s springing from materialistic and mechanistic bases are blurring at the edges. Although the behavioral sciences continue to rely largely on traditional interpretations, the physical sciences are striding into mysti­ cism. Hence, to assume that a linear developm ent of current scientific knowledge will subsume the usable knowledge of the future is to fall into what Richard H. Bube, a professor of material sciences and electrical engineering at Stanford University, has labeled “one of the most pernicious false­ hoods ever to be almost universally accepted. W hen taken together, the similar strands woven through existing mythic, religious, and scientific accounts suggest a “lost” historical record.
