CCT Respiratory

Diaphram is innervated by... a branch of the phrenic nerve originating at C3-C5.
Diapram is... -Primary muscle of inspiration -Contracts and flattens during inspiration, increasing intrathoracic Volume -responsible for 75% of TV during normal inspiration, quiet breathing -Divided into left and right "leaves"
Intercostals... -Important secondary muscles of inspiration Elevates the ribs, increasing anterior-posterior diameter and volume of thorax -Innervated by intercostal nerves which originate at T1-T11
Scalenes and Sternocleidomastoid -Accessory muscles of inspiration -Lift sternum and ribs upward and out, increasing intrathoracic volume
Explain the passive act of inspiration: The diaphram draws downward and this action
Explain the act of expiration: Recoil of the chest decreases the intrathoracic volume and increase pressure.
Oxyhemoglobin dissociation curve: Graphic (sigmoidal curve) representation of the relationship between Hb saturation and the partial pressure of O2 (PaO2). - determined in "normal" blood with a pH of 7.4 and a temperature of 37c
Right shift: -More O2 released from teh hemoglobin, resulting in greater O2 delivery to tissue Right shift causes: -Increase of PCO2 -Increased temperature -Increased 2,3-DPG -Decreased pH (acidosis)
Left shift: -O2 released by the hemoglobin at significantly lower PO2 resulting in decreased O2 delivery to tissues -Left shift causes: -Decrease in PCO2 -Decreased temperature -Decreased 2,3-DPG -Increased pH (alkalosis) Carbon monoxide poisoning
History and Physical particular to what? Cardiac and respiratory histories
History and Physical Exam: Determine if the patient has ever required the following: -Intubation -Mechanical ventilation -Hospitalization -Home oxygen use
COPD defined clinically as the presence of a productive cough for: for three months out of the year for two years in a row
Radiogragh: -A/P and lateral films -Hyperinflation...what will you see? -Flattened, low diaphragm -Hyperlucent lung fields -Wide intercostals spaces -Long, narrow heart shadow -Dimished vascular markings -dilated bronchioles -Bullae, blebs
COPD and pulse oximetry... -Cannot identify hypercapnia or acid based disturbances -Useful and conveinient for assessing oxygenation and monitoring oxygen saturation during treatment *Instant feedback on patient status *<90% requires aggressive therapy
Chronic bronchitis: is what?
Chronic bronchitis and pulse oximetry... -Useful and conveinient for assessing oxygenation and monitoring oxygen saturation during treatment *Instant feedback on patient status *<90% requires aggressive therapy
Chronic bronchitis and EKG you would use to evaluate what? to evaluate hypoxia-induced ischemia
Chronic bronchitis and blood glucose, you would see what possibly? -Hyperglycemia secondary to: *Stress *Use of B-agonists, corticosteroids -Hypoglycemia *Increased work *Poor stores
COPD treatment: -Aimed at achieving *PaO2 >60 mmHg *SaO2 >90% -monitor ABG to rule out developing hypercapnia secondary to O2 administration -Humidified O2 to assist in the mobilization of secretions

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
