Respiratory failure - Case Study Example A fall arterial oxygen tension (Pa, O2) of 6.0 kPa (45 mmHg) or both, is indicative of respiratory failure (Roussos and Koutsoukou, 2003). Respiratory failure may be acute or chronic. In case of Wilson, the respiratory failure is acute and this is indicated by the drastic change in the acid-base status (pH= 7.3). The cause of respiratory failure in him is the right lower lobe collapse-consolidation secondary to pneumonia. Lower respiratory tract infection is known as pneumonia. The pathology lies in the parenchyma of the lungs which consist of alveolar sacs. There are several causes of pneumonia, the most common of which is bacterial (Stephen, 2009). Bacterial pneumonia can be community acquired or hospital-acquired. In case of Wilson, the pneumonia is hospital acquired. Â  Decreased oxygen saturation: Acute respiratory failure occurs when the body is unable to maintain gas exchange at a rate on par with the demands of the body like in pneumonia. The damage to lung parenchyma in pneumonia results in the release of inflammatory mediators and fluids because of which intrapulmonary shunting, ventilation-perfusion mismatching, hypoventilation and diffusion defects occur (Stephen, 2009). All these eventually lead to hypoxemia which is evident in the blood gas analysis of Wilson (Ranjit, 2001). In ventilation-perfusion mismatch, areas which have lower ventilation as against perfusion contribute to hypoxemia.

Ethnic Style in Male-Female Conversation Research Paper

Ethnic Style in Male-Female Conversation - Research Paper Example Only then two people communicating with each other can understand each other with the shared identity. On the other hand, where there is lack of a common chord in conversational strategies, feelings of disharmony, not being understood are created. In this way, conversational style becomes a major element of ethnicity. Every language has distinct words to interpret specific objects which are different in other languages. However, signalling intentions and attitudes depend on personal styles of individuals. The conversational style is â€Å"both a consequence and indicator of ethnicity† (Tannen, 1982, p.230). Indirectness which is a roundabout way of saying a particular thing is a stamp of one’s distinct style and personality which changes according to situations. It means not explicitly stating what one wants and the meaning is inferred by the listener based on previous conversations and expectations and also from â€Å"culturally agreed upon meanings that are associated with particular expressions† (Tannen, 2006, p.361). This way of expressing through conversation is a means of satisfying the coexisting and conflicting positive and negative forces. For instance, when one wants to be left alone, he will not say it directly as he will not want to cause displeasure to others. He will apply the strategy for an indirect way of saying the same. Indirectness is a manner in which one can fulfil the purpose of both rapport and defensiveness. By rapport, it means a subtle way of expressing one’s desire and getting it fulfilled. It means the desire expressed in a way that it i s understood without being explained. Defensiveness means the strategic way of saying a particular thing which keeps the door open for reneging if the conversation is not accepted favourably by others. For instance, one can always say later on â€Å"I never said that† or â€Å"that isn’t what I meant† (Tanner, 1982, p.218). Since conversational strategies and degrees of indirectness often vary with cultural differences between individuals, therefore misunderstandings even from simple conversations can emerge more in cross-cultural communication.
