Anatomy of lower airway - Study guides, Class notes & Summaries

Tidal Volume (TV) - is the volume of air moved in an out of the respiratory (breathed) during each ventilatory cycle Crepitus - a grating sound or sensation produced by friction between bone and cartilage or the fractured parts of a bone. Anatomy of Upper Airways - NOTE: -epiglottis -pharynx -larynx Anatomy of Lower Airway - Oxygen-Hemoglobin Dissociation Curve - -When the need for oxygen is greater in tissues, hemoglobin will dissociate oxygen even faster than when tissues have less n...

A nurse is caring for an older adult client who has pneumonia. Which of the following physiologic changes associated with aging places the client at a greater risk for pneumonia? A. Decreased anterior-posterior diameter B. Increased diameter of the small airways C. Decreased number of cilia D. Increased alveolar surface area - Answers >>C. Decreased number of cilia Decreased anterior-posterior diameterA physiologic change associated with aging is a calcification of the bronchial and costal...

electrical conduction of the heart The flow of electrical current causes smooth, coordinated heart contractions; they produce pumping action of the heart Depolarization electrical charges on the surface of the muscle cell change from positive to negative Repolarization the heart returns to its resting state, and the positive charge is restored to the surface Where do the electrical impulses begin? Electrical impulses begin high in the atria in the sinoatrial node, travel to the atrioventr...

Variations in pediatric anatomy and physiology - Respiratory CORRECT ANSWER Nose -Newborns are obligatory nose breathers until at least 4 weeks old (breathe through nose when cyring; want to make sure nose is clear - use nose aspirator) -Infants have very small nasal passages -Frontal and sphenoid sinuses not completely developed until 6-7 yrs old (less susceptible to get infections) Throat -Infant tongue relatively large to the oropharynx -Enlarged tonsils and adenoids (shrink over time) ...

What are techniques for clearing an obstructed airway? - ANSWER -Chest compressions (unconscious) -Suctioning -Rolling to side (left for pregnant women) -Magill forceps (to be used with laryngoscope) -Abdominal thrusts -Manual removal if you can see it What are indications for removing an airway adjunct? - ANSWER OPA: remove if gag reflex intact NPA: remove if the patient cannot tolerate What are indications for nasotracheal intubation? - ANSWER -Anticipated difficult laryngoscopy -...

The ultimate FISDAP AIRWAY study guide, 926 Questions and Correct Answers, With Complete solution. 2024/2025. From the atmosphere, what structures does air pass through during ventilation? Starts in atmosphere, then nose, nasopharyngeal space/orophargyneal space (if mouth breather), then pharynx, larynx, trachea, bronchi, bronchioles, alveoli What is the purpose of the nasal passages and nasopharynx? To warm/humidify air as it passes through What is the difference between respiration and ...

Chapter 11 Respiratory Disorders ANATOMY AND PHYSIOLOGY Upper airway = nasopharynx and oropharynx connected to the ears by the eustachian tubes. The nose, pharynx, and larynx are separated from the lower airway by the trachea. The larynx is covered by the epiglottis. Cilia and mucus in the nostrils warm, clean, and humidify the air. Lower airway = trachea, bronchi, bronchioles, and alveoli. Left lung = two lobes/ Right = three lobes. At the capillaries = oxygen and carbon dioxide diffuse...
