|
Ventilation |
Process of moving gas in and out of the lungs |
|
|
Hypoxia |
Abnormal condition in which O2 available to the body cells is inadequate to meet metabolic needs. |
|
|
Hypoxemia |
Abnormal deficiency of O2 in the arterial blood |
|
|
Incentive spirometry |
Process of encouraging a bed ridden patient to take deep breaths to avoid atelectasis. |
|
|
lobar atelectasi |
when ventilation is compromised to a larger airway or bronchus |
|
|
continuous positive airway pressure |
method of ventilator support where y the patient breathes spontaneously with support of non invasive positive airway pressure to keep airways open. |
|
|
compression atelectasis |
collapse of a part of the lung as a result of an external force compressing the lung |
|
|
hypo ventilation |
ventilation that does not meet metabolic needs. |
|
|
tidal volume |
the normal tidal volume refreshes the gas present in the lung removing co2 and supplying O2 |
|
|
gas absorption atelectasis |
complete interruption of ventilation to a section of the lung |
|
|
apnea |
absence of breathing |
|
|
depolarization |
causes the cardiac muscle cell ti contract momentarily |
|
|
cheyne strokes respiration |
respiration rate and tidal volume gradualy increase and then gradually decrease to a complete apnea |
|
|
dysoxia |
abnormal metabolic state in which the tissues are unable to use the O2 made availability properly. |
|
|
leukopenia |
low white blood cell count |
|
|
leukocytosis |
elevated white blood cell count |
|
|
erythrocytes |
red blood cells |
|
|
what is cardiac output? |
the total amount of blood pumped by the heart per minute. |
|
|
what is end-systolic volume? |
the blood not ejected after systole |
|
|
what is congestive heart failure |
the pumping efficiency of the heart is so slow that cardiac output is inadequacy to meet tissues needs |
|
|
vagovagal reflexes |
reflexes caused by stimulation of parasympathetic receptors in the airways that can result in laryngospasm bronchaconstrictioin and |
|
|
biots respiration |
similar to cheyne-strokes respiration except that tidal volumes are of identical depth it occures in patients with increased ICP. |
|
|
sinus arrhythmia |
a common arrhythmia and is recognized by the irregular spacing between QRS complexes |
|
|
atelectasis |
alveolar collapse |
|
|
alveolar dead space |
the volume of gas ventilating being unperfused |
