|
Incentive spirometry
|
encourages voluntary deep breathing by providing visual feedback to patients about inspiratory volume
|
|
|
Noninvasive positive pressure ventilation
|
Is used to prevent using invasive artificial airway in patients with acute respiratory failure cardiogenic pulmonary edema, or exacperation of COPD
|
|
|
Continuous positive airway pressure CPAP
|
Patient with obstructive sleep apnea patients with heart failure in preterm infants with undeveloped lungs
|
|
|
Bilevel positive airway pressure (BiPAP)
|
Provides both inspiratory positive airway and expiratory airway pressure
|
|
|
Chest tube
|
The catheter inserted through the thorax to remove air influence from the pleural space or retaining air or fluid
|
|
|
Pneumothorax
|
Is a collection of air in the pleural space
|
|
|
Hemothorax
|
Is an accumulation of blood and fluid in the pleural cavity between parietal and visceral pleura usually as a result of trauma.
|
|
|
Ventilation
|
process of moving gases into and out of the lungs
|
|
|
Perfusion
|
pumps oxygenated blood to the tissues and return deoxygenated blood to the lungs
|
|
|
Inspiration
|
is an active process, stimulated by chemical receptors in the aorta.
|
|
|
Expiration
|
is a passive process that depends on the elastic recoil properties of the lungs, requiring little or no muscle work.
|
|
|
Surfactant
|
is a chemical produced in the lungs to maintain the surface tension of the alveoli and keep them from collapsing.
|
|
|
Atelectasis
|
is a collapse of the alveoli that prevents normal exchange of oxygen and carbon dioxide.
|
|
|
Stoke volume
|
volume of blood ejected from the ventricles during systole
|
|
|
Cardiac output
|
the amount of blood ejected from the left ventricle each min. (4-6L/min) @rest
|
|
|
pre-load
|
is the end-diastolic volume
|
|
|
After-load
|
is the resistance to the left ventricular ejection.
|
|
|
Electrocardiogram
|
reflects the electrical activity or condition system
|
|
|
Normal sinus rhythm (NRS)
|
normal sequence on the ECG
|
|
|
Hypovolemia
|
condition such as shock or server dehydration causes extracullar fluid loss and reduced circulating blood volume
|
|
|
Hypoventilation
|
occurs when alveolar ventilation is inadequate to meet the oxygen demand of the body or eliminate suffice carbon dioxide
|
|
|
Hypoventilation
|
is a state of ventilation in which the lungs remove carbon dioxide faster than it is produced by cellular metabolism
|
|
|
Hypoxia
|
is inadequate tissue oxygenation at the cellular level
|
|
|
dysthymias
|
a devation from the normal sinus v heart rhythms
|
|
|
ventrivular tachycardia & fibrillation
|
are life threatening rhythms that require immediate interventions
|
|
|
Myocardial ishemia
|
a result when blood supply to the myocardium from the coronary arteries is insufficient to meet myocardium oxygen demands
|
|
|
Angina pectoris
|
a transient imbalance between myocardial oxygen supply and demand
|
|
|
Myocardial infraction or Acute coronary syndrome
|
results from sudden decreased in coronary blood flow or an increase in myocardial oxygen demands without adequate coronary perfusion
|
|
|
Dysphea
|
is a clinical sign of hypoxia
|
