Q

acute respiratory distress syndrome (ARDS)

A

nonspecific pulmonary response to a variety of pulmonary and non pulmonary insults to try lung; characterized by interstitial infiltrates, alveolar hemorrhage, atelectasis, refractory hypoxemia, and with the exception some patients with covid and ARDS, decreased compliance

Q

airway pressure release ventilation (APRV)

A

mode of mechanical ventilation that allows unrestricted, spontaneous breaths throughout the ventilatory cycle; on inspiration the patient receives a preset level of continuous positive airway pressure, and pressure is periodically released to aid expiration

Q

continuous mandatory (volume or pressure) ventilation (CMV)

A

also referred to as assist-control (AC) ventilation; mode of mechanical ventilation in which the patient’s breathing pattern may trigger the ventilator to deliver a preset tidal volume or set pressure; in the absence of spontaneous breathing, the machine delivers a controlled breathing at a preset minimum rate and tidal volume or set pressure.

Q

continuous positive airway pressure (CPAP)

A

positive pressure applied throughout the respiratory cycle to a spontaneously breathing patient to promote alveolar and airway stability and increase functional residual capacity; may be given with endotracheal or tracheostomy tube or by mask

16
Q

hemothorax

A

partial or complete collapse of the lung due to blood accumulating in the pleural space; may occur after surgery or trauma

17
Q

hypoxemia

A

decrease in oxygen tension in the arterial blood

18
Q

hypoxia

A

decrease in oxygen tension in the arterial blood

19
Q

incentive spirometry

A

method of deep breathing that provides visual feedback to help the patient inhale deeply and slowly to achieve maximum lung function

20
Q

induration

A

an abnormally hard lesion or reaction, as in a positive tuberlin skin test

21
Q

intermittent mandatory (volume or pressure) ventilation (IMV)

A

mode of mechanical ventilation that provides a combination of mechanically assisted breaths at a preset volume or pressure and rate and spontaneous breaths

22
Q

mechanical ventilator

A

a positive or negative pressure breathing device that supports ventilation and oxygenation

23
Q

orthopnea

A

shortness of breath when reclining or in supine position

24
Q

pleural effusion

A

abnormal accumulation of fluid in the pleural space

25
pleural friction rub
localized grating or creaking sound caused by the rubbing together of inflamed parental and visceral pleurae ; a potential space
26
pneumothorax
partial or complete collapse of the lung due to positive pressure in the pleural space
27
positive end-expiratory pressure (PEEP)
positive pressure maintained at the end of exhalation (instead of a normal zero pressure) to increase functional residual capacity and open collapsed alveoli
28
pressure support ventilation (PSV)
mode of mechanical ventilation in which preset positive pressure is delivered with spontaneous breaths to decrease work of breathing
29
proportional assist ventilation (PAV)
mode of mechanical ventilation that provides partial ventilatory support in proportion to the patient’s inspiratory efforts; decreases the work of breathing
30
purulent
consisting of, containing, or discharging pus
31
respiratory weaning
process of gradual, systematic withdrawal or removal of ventilator, breathing tube, and oxygen
32
restrictive lung disease
disease of the lung that causes a decrease in lung volumes
33
synchronized intermittent mandatory ventilation (SIMV)
mode of mechanical ventilation in which the ventilator allows the patient to breathe spontaneously while providing a preset number of breaths to ensure adequate ventilation; ventilated breaths are synchronized with spontaneous breathing
34
tension pneumothorax
pneumothorax characterized by increasing positive pressure in the pleural space with each breath; this is an emergency situation, and the positive pressure needs to be decompressed or released immediately
35
thoracentesis
insertion for a needle or catheter into the pleural space to remove fluid that has accumulated and decrease pressure on the lung tissue; may also be used diagnostically to identify potential causes of a pleural effusion
36
thoracotomy
surgical opening into the chest cavity
37
tidal volume
volume of air insured and expired with each breath
38
tracheostonomy tube
indwelling tube inserted directly into the trachea to assist with ventilation
39
transbronchial
through the bronchial wall, as in a tranbronchial lung biopsy
