Physiology
This process refers to the movement of air in and out of the lungs, driven by pressure differences between the atmosphere and the lungs.
What is ventilation?
In the cardiovascular system, this late sign of inadequate oxygenation is marked by a bluish discoloration of the lips, face, or extremities due to reduced oxygen levels in the blood.
What is cyanosis?
This process helps to remove large particles from the air before they reach the lungs, as the nasal passages and upper airways filter out dust, allergens, and microorganisms.
What is filtration of air?
This subjective symptom, often described as shortness of breath, can occur with respiratory distress and is an important indicator in respiratory assessments.
What is dyspnea?
This type of health behavior involves a patient avoiding smoking, using appropriate preventive measures, and seeking regular medical care for respiratory conditions.
What is health promotion or health management?
The primary role of this gas exchange process is the movement of oxygen from the alveoli into the bloodstream and the removal of carbon dioxide from the blood to the alveoli.
What is oxygenation?
This early respiratory sign of inadequate oxygenation is characterized by an increased rate of breathing as the body tries to compensate for low oxygen levels.
What is tachypnea?
This defense mechanism involves tiny hair-like structures in the respiratory tract, which move mucus and trapped particles upwards toward the throat to be expelled or swallowed.
What is mucociliary clearance?
A patient reports having a persistent cough that produces yellow-green mucus, a common symptom in this type of respiratory infection.
What is a bacterial infection?
This dietary modification may be recommended for patients with respiratory issues to help maintain proper lung function and improve energy levels.
What is a high-protein, high-calorie diet?
This term refers to the ability of the lungs and chest wall to stretch and expand in response to changes in pressure during breathing.
What is compliance?
This central nervous system manifestation, which can occur with inadequate oxygenation, is characterized by confusion or a reduced ability to think clearly.
What is confusion or altered mental status?
This protective reflex occurs when irritants such as dust or smoke trigger a forceful expulsion of air from the lungs, helping to clear the airways.
What is the cough reflex?
When assessing for respiratory issues, a patient mentions feeling tightness in the chest, especially when breathing. This can be a common symptom in conditions like asthma.
What is chest tightness?
A patient with a severe respiratory condition such as asthma may experience this cognitive symptom due to low oxygen levels during an exacerbation.
What is confusion or altered mental status?
These specialized receptors, located in the aortic arch and carotid arteries, detect changes in blood oxygen, carbon dioxide, and pH levels to help regulate breathing.
What are chemoreceptors?
This late respiratory manifestation occurs when the body is no longer able to compensate for insufficient oxygen, and the person experiences slow, irregular breathing.
What is bradypnea?
This defensive response in the airways causes the smooth muscles to contract, narrowing the bronchi, and is often triggered by irritants to protect the lungs from harmful substances.
What is reflex bronchoconstriction?
A patient with a history of smoking reports a long-standing dry cough, particularly in the mornings. This could be indicative of this chronic respiratory condition.
What is chronic obstructive pulmonary disease (COPD)?
Difficulty concentrating and a sense of fatigue can occur when respiratory distress leads to inadequate oxygenation, impacting this functional health pattern.
What is cognitive function?
This type of receptor, found in the airways and lungs, responds to mechanical changes such as stretch and pressure, and plays a role in regulating breathing patterns and preventing lung over-expansion.
What are mechanical receptors (e.g., stretch receptors or pulmonary stretch receptors)?
In the cardiovascular system, this sign of inadequate oxygenation is characterized by a rapid, weak pulse and is often accompanied by hypotension.
What is tachycardia or weak pulse?
These immune cells, located in the alveoli, engulf and digest pathogens, dust, and other foreign particles to prevent infection and maintain lung health.
What are alveolar macrophages?
A patient describes feeling more breathless when lying flat, which is a key symptom of this condition that can lead to fluid buildup in the lungs.
What is orthopnea (often seen in heart failure)?
A patient with severe chronic respiratory issues may develop this problem, which can be aggravated by the strain of coughing.
What is constipation?
