Qui si parla del luogo di nascita di Oliver Twist e delle circostanze che si riferiscono alla sua venuta al mondo.

Non voglio dichiarare che il nascere in un ospizio per poveri rappresenti una circostanza di favore per un essere umano; tuttavia, per Oliver Twist si rivelò come un colpo di

fortuna. I suoi polmoni si rifiutavano di lavorare e solo dopo notevoli sforzi si riuscì a convincerli a respirare… … Così per qualche tempo egli rimase immobile nella sua cuccia, incerto se restare in questo basso mondo o volarsene verso uno migliore. (to be continued)

Uso di ossigeno in sala parto Che concentrazione di ossigeno somministrare in corso di bradicardia (FC<60bpm) nonostante ventilazione efficace? Quale è l’effetto della somministrazione di aria ambiente in
