Examples of bronchopulmonary segment in the following topics:

  • Lobes, Fissures, and Lobules

    • It bears apical, anterior, and posterior bronchopulmonary segments.
    • It bears medial and lateral bronchopulmonary segments.
    • It bears medial, lateral, superior, anterior, and posterior bronchopulmonary segments.
    • The upper lobe of the left lung contains anterior and apicoposterior bronchopulmonary segments.
    • It contains superior and inferior bronchopulmonary segments.
  • Bronchi and Subdivisions

    • The lobar bronchi (also called secondary bronchi) divide into tertiary bronchi, each of which supplies air to a different bronchopulmonary segment.
    • A bronchopulmonary segment is a distinct region of the lung separated from the rest of the lung by connective tissue.
    • Each bronchopulmonary segment forms a discrete functional unit in the lung that is independent of the other segments.
    • This property allows a bronchopulmonary segment to be surgically removed without affecting other segments.
    • There are 10 segments in the right lung and 8 to 9 segments in the left lung due to anatomical differences.
  • The Importance of Market Segmentation

    • Market segmentation allows for a better allocation of a firm's finite resources.
    • Market segmentation can be defined in terms of the STP acronym, meaning Segment, Target and Position.
    • While there may be theoretically 'ideal' market segments, in reality, every organization engaged in a market will develop different ways of imagining market segments, and create product differentiation strategies to exploit these segments.
    • To increase marketing efficiency by directing effort specifically toward the designated segment in a manner consistent with that segment's characteristics
    • Rather, one or more target markets (segments) must be selected.
  • Developing a Market Segmentation

    • This allows them to focus all of their efforts on a single segment.
    • There are two major segmentation strategies followed by marketing organizations: a concentration strategy and a multi-segment strategy.
    • This strategy is advantageous because it enables the organization to analyze the needs and wants of only one segment and then focus all its efforts on that segment.
    • In the multi-segment strategy, a company focuses its marketing efforts on two or more distinct market segments.
    • Markets could also be segmented by usage rates.
  • Evaluating Market Segments

    • Segmentation involves classifying people into homogeneous groupings and determining which of these segments are viable target markets.
    • Rather, one or more target markets (segments) must be selected.
    • Thus, market segmentation is a twofold process that includes:
    • An ideal market segment meets all of the following criteria:
    • The other segmentation strategy is a multisegment strategy.
  • Determining Segmentation Variable(s)

    • Markets can be segmented primarily according to geographic, demographic, usage, and psychological segments--or a combination of the above.
    • As noted, religion is an interesting basis for demographic segmentation.
    • Segmenting the consumer market by age groups is useful for several products.
    • Gender has historically been a good basis for market segmentation.
    • The heavy user is an important basis for segmentation.
  • Respiratory Syncytial Virus Infection

    • A prophylactic medication (not a vaccine) exists for preterm-birth (under 35 weeks gestation) infants, and for infants with a congenital heart defect or bronchopulmonary dysplasia.
  • Estimating the Addressable Market

    • The market can be categorized into separate groups called segments.
    • Any discrete variable is a segmentation.
    • Segments can be obtained by any number of approaches.
    • Minimally, an existing discrete variable may be chosen as a segmentation, also called "a priori" segmentation.
    • Each entity in the delivery chain will have different needs, so a complete market needs analysis must include all potential segments and all entities within each segment.
  • Identifying the Target Market

    • In addition to the above segmentations, market researchers have advocated a needs-based market segmentation approach to identify smaller and better defined target groups.
    • Identify clusters of similar needs - Demographics, lifestyle, usage behavior and pattern is used to differentiate between segments.
    • Apply a valuation approach - Market growth, barriers to entry, market access, and switching is used to valuate segments.
    • Test the segments - A segment storyboard is created to test the attractiveness of each segment's positioning strategy.
    • Modify marketing mix - The segment positioning strategy is expanded to include all aspects of the marketing mix.
  • Concentrated Targeting

    • Concentrated marketing is a strategy which targets very defined and specific segments of the consumer population.
    • For example, the manufacturer of Rolex watches has chosen to concentrate on the luxury segment of the watch market.
    • An organization that adopts a concentration strategy gains an advantage by being able to analyze the needs and wants of only one segment and then focusing all its efforts on that segment.
    • However, there is no increase in the total profits of the sales as it targets just one segment of the market.
    • The primary disadvantage of concentration strategy is related to the demand of the segment.
