Respiratory Flashcards
capillaries are where
exchange of nutrients/oxygen and waste products occur
gas exchange happens in the
alveoli
ventilation is the
air movement in and out of the lungs
oxygenation is the
oxygen in the blood stream
perfusion is the
oxygen in the tissues
Airway = _________
Breathing = _________
Circulation = ____________
Ventilation
Oxygenation
Perfusion
Flow in respiratory support is
how many L/min of gas is flowing into the client; low flow or high flow
Fraction of Inspired Oxygen (FiO2) is
percent of the gas that is oxygen
Types of pressure respiratory support are
CPAP and BiPAP
CPAP stands for
continuous positive airway pressure
BiPAP stans for
Bilevel positive airway pressure
what does CPAP do
delivers air pressure at single set level that stays consistent during sleep; inhalation and exhalation is a constant set pressure
CPAP is not as good for ____________ and is usually used for
accommodating breathing changes; obstructive sleep apnea
what does BiPAP do
uses two two different pressure settings for inhale vs exhale and allows for lower pressure during exhalation; inhale is at a constant set pressure and exhale is set at a lower constant set pressure
BiPAP is used for
complex breathing problems such as central sleep apnea, and heart/lung/neurological disorders that require additional airway support during sleep (CHF, COPD, Parkinson’s, ALS)
High ventilator alarm means
pressure in circuit is too high
Causes of high ventilator alarms
coughing, gagging, bronchospasm, fighting the ventilator, ETT occlusion, kink in tubing, increased secretions, thick secretions, water in ventilator circuit
Low ventilator alarm means
pressure in the circuit is too low
Causes of low ventilator alarms
tubing is disconnected, loose connections, leak, extubation, cuffed ETT or trach is deflated, poorly fitting CPAP/BiPAP mask
ETT placement should be verified by a
CXR and assessment of equal breath sounds
An ETT can become displaced into the ________ main stem bronchus
right
tracheostomy infection risk is high because
natural defenses of the nose and mouth are bypasse
prevent trach infections by
daily trach care and which is a sterile procedure
positioning for trach pts should be
fowlers or semi-fowlers
how to suction a trach
only to pre measured depth
don’t suction for longer than 10 seconds
insert suction catheter and apply suction catheter on the way out
some clients may need to be pre-oxygenate with 100% FiO2
____ fingers should fit underneath a trach tie
1
at the bedside of a trach pt you need to have
two back up trachs: 1 of the same size and 1 half a size smaller
Indications for chest tube
Pneumothorax
Effusions (pleural)
Abscess
Cancer (lung)
Hemothorax
________ chamber is connected to suction on chest tube system
suction control chamber
in the suction control chamber there should be ___________ bubbling
gentle bubbling
in the water seal chamber there should be __________ bubbling
intermittent bubbling
the ___________ chamber is connected to the pt in a chest tube system
drainage collection chamber
the drainage collection chamber should have _________ bubbling
no bubbling
the drainage system for a chest tube should always be kept
below the level of the client’s chest
