Respiratory Procedures- Stasio Flashcards
What can make pulse oximetry readings less accurate
hypothermia- decreased peripheral circulation
fingernail polish
cannot discriminate between oxyhemoglobin and carboxyhemoglobin
If dont correctly what will a CXR show you
9-10 ribs posteriorly and 5-6 anteriorly
When do you order a CXR
suspect disease in that area
suspect systemic disease with chest involvement
monitor life-support devices
pneumoperitoneum (gas in abcdominal cavity)
What is RIP when reading CXR
rotation, inspiration and penetration
normal heart size on CXR is what
transverse size of heart divided by transverese diameter of thorax shoul dbe <.5
What side of diaphragm is higher on CXR
the right is higher from liver
What does penetration refer to on CXR
under or over penetrated
what does inspiration of CXR refer to
ddiaphragm to the 9-10 rib
on PA view the heart looks enlarged, why?
divergence of x ray beams
What is seen on CXR of early COPD/chornic bronchitis/asthma
hyperinflation, loss of vascular markings, flattened hemidiaphragms, inc PA diamteres, inc retrosternal air space
ABG is used to determine what
pH of blood pp O2 in blood pp CO2 in blood HCO3 level O2 sat Hb
Where are the common sites to pull ABG from
radial a, brachial a and femoral
what are indications for ABG
assess for hypoxia
evaluate acid base
need for home O2?
measure carboxyHb levels in smoke inhalation patients or exposure (CO)
calculate arterial O2 sat
blood sample in dificult draw patients (obese)
How do you calculate actual O2 sat in ABG
O2 sat- CO Hb = actual O2 sat
What are the absolute contraindications to ABG
none
what are the relative contraindications to ABG
invasive procedure
coagulopathy
severe PAD with poor collaterals (allens test)
trauma of infection at draw site
difficult to standarize from factors: hyperventilation, breath holding, altitude, obesity
What is equipment for ABG collection
sterile gloves rolled towel ice for transport ABG kit and lidocaine if desired
What is in ABG kit
2 ml heparinized syringe with 25 gauge needle, iodophor and alcohol pads, 2x2 sterile gauze and band-aid
describe cleaning process before arterial draw
cleab with iodophor then wipe once with alcohol pad
at what angle do you insetrt needle for ABC
45 to skin, bevel up and slowly advance till artery is puntured
how much blood do you collect for ABG
2-3mL
how long do you apply pressure after stick
5 minutes or until no bleeding occurs
describe traction on skin for ABG draw
locate a with index and middle finger and speard apart
What are indications for ET/NT intubation
respiratory failure airway protection maintenance of airway facilitate pulm Tx and medication use + P ventilation maintain adequate oxygenation
what are contraindications to ET/NT intubation
operator unskilled to administer tube
excessive trauma to face, neck and c spine
inability to extend head and neck
What is key for reparing ET tube placement
most appropriate method all equipment must be functioning have adequate IV access! removed any foreign bodies hyperventialte monitor BP, pulse ox and cardiac status
