What occurs when a patient is breathing very rapidly and shallowly? Select oneQuestion 80Answera.Air moves primarily in the anatomic dead space and does not participate in pulmonary gas exchange.b.Minute volume increases because of a marked increase in both tidal volume and respiratory rate.c.The majority of tidal volume reaches the lungs and diffuses across the alveolar-capillary membrane.d.Air is forcefully drawn into the lungs due to the negative pressure created by the rapid respirations.

When a patient's respirations are too rapid and too shallow:Question 68Answera.minute volume increases because a larger amount of air reaches the lungs.b.the majority of inhaled air lingers in areas of physiologic dead space.c.the increase in tidal volume will compensate for a rapid respiratory rate.d.inhaled air may only reach the anatomic dead space before being exhaled.

Main articles: Breathing and Lung volumesThe lungs expand and contract during the breathing cycle, drawing air in and out of the lungs. The volume of air moved in or out of the lungs under normal resting circumstances (the resting tidal volume of about 500 ml), and volumes moved during maximally forced inhalation and maximally forced exhalation are measured in humans by spirometry.[12] A typical adult human spirogram with the names given to the various excursions in volume the lungs can undergo is illustrated below (Fig. 3):

explain the difference between shallow and deep breathing. Propose which muscles are involved and what difference it makes.

After the expiration of a normal tidal volume, a subject breathes in as much air aspossible. The volume of air inspired is thea) inspiratory reserve volume.b) vital capacity.c) inspiratory capacity.d) d. total lung capacity.e) functional residual capacity.

Gases constantly move in and out of theblood into the lungs. Identify the gasesthat move in and out of the respiratorysystem
