Respiratory Anatomy
A detergent-like phospholipid, reduces the surface tension between the moist membranes of the alveoli, preventing their collapse.
What is Surfactant?
Decreased oxygen supply to the heart caused by insufficient blood supply, can lead to impaired oxygenation of tissues in the body.
What is Myocardial Ischemia?
Blood is squeezed through the heart and out into the body by contractions starting in this part of the heart.
What is the atria?
What is tachypnea?
An artificial opening made into the trachea, usually at the level of the second or third cartilaginous ring.
What is a tracheostomy?
Microscopic hair-like projections, propel trapped material and accompanying mucus toward the upper airway so they can be removed by coughing.
What is Cilia?
This is when the heart is unable to pump a sufficient blood supply, resulting in inadequate perfusion and oxygenation of tissues.
What is Heart failure?
Carried from the right side of the heart to the lungs, where oxygen is picked up and carbon dioxide is released, and then returned to the left side of the heart.
What is deoxygenated blood?
A nurse is caring for a patient with COPD. What would be an expected finding upon assessment?
What is Dyspnea?
A polyvinyl chloride airway that is inserted through the nose or mouth into the trachea, using a laryngoscope as a guide. It is used to administer oxygen by mechanical ventilator, to suction secretions easily, or to bypass upper airway obstructions.
What is an Endotracheal tube?
Small air sac clusters at the end of the terminal bronchioles where gas exchange occurs.
What are alveoli?
A disturbance of the rhythm of the heart caused by an abnormal rate of electrical impulse generation from the SA node, or from impulses originating from a site or sites other than the SA node.
What is dysrhythmia?
A mass of tissue in the upper right atrium, just below the opening of the superior vena cava.
What is the sinoatrial (SA) node?
A nurse is caring for a patient who has been hospitalized for an acute asthma exacerbation. Which testing method might the nurse use to measure the patient's oxygen saturation?
What is pulse oximetry?
A semicircular tube of plastic or rubber inserted into the back of the pharynx through the mouth or nose in a patient who is breathing spontaneously.
What is an Oropharyngeal and nasopharyngeal airway?
The movement of gas or particles from areas of higher pressure or concentration to areas of lower pressure or concentration.
What is Diffusion?
A temporary imbalance between the amount of oxygen needed by the heart and the amount delivered to the heart muscles, causing chest pain or discomfort.
What is angina?
This node initiates the transmission of electrical impulses, causing contraction of the heart at regular intervals.
What is the SA node?
A nurse is assisting a respiratory therapist with chest physiotherapy for patients with ineffective cough. For which patient might this therapy be recommended?
What is A teenager with cystic fibrosis?
Uses mild air pressure to keep airways open.
What is Positive Airway Pressure (PAP)?
Incomplete lung expansion is known as this.
What is Atelectasis?
A rapid heart rate.
A mass of tissue located at the bottom of the right atrium.
What is the atrioventricular (AV) node?
A nurse is suctioning the nasopharyngeal airway of a patient to maintain a patent airway. For which condition would the nurse anticipate the need for a nasal trumpet?
What is A nosebleed noted with continued suctioning?
Provides continuous mild air pressure to keep airways open.
