Most common type of delirium in the ICU

Mixed delirium 

100

Receptors involve in Dyspnea sensation (3)

Chemoreceptors peripheral (carotid bodies and aortic arch)  and central (located in the medulla) PH / CO2 

Upper airway receptors: Innervated by the trigeminal nerve (Fan) 

Chest wall Mechanoreceptors

Pulmonary receptors:  via the vagus nerve:

●Pulmonary stretch receptors,  activated by increase in tension in the walls of airways,(hyperinflation). Slowly adapting receptors

●Irritant receptors:  Stimulated by mechanical stimuli, or inhalation of irritants. Rapidly adapting 

●  Juxta pulmonary capillary receptors (c fibers) stimulated by mechanical and chemical factors.

Survival after withdrawal of dialysis (ambulatory)

7 to 10 days

Opioid receptors in the respiratory system

 mu-opioid receptors

200

Percentage of VC at which PEG should be place in ALS patients

PEG should be placed when vital capacity (VC) falls to 50 percent of predicted. There is increased morbidity of the procedure as respiratory function declines.

200

Average 5 year survival in dialysis patients

50%

Life expectancy 25% of non renal pts 

25% Die after decision to D/C dialysis


200

Opioid for ICU patients with renal failure

 Fentanyl

300

Medications that need to be stopped in a patient with hypercalcemia (3)

Thiazide, Digoxin, Lithium Ca supplements theophylline, tamoxifen, Vitamin A and D

300

 Mechanisms by which supplemental oxygen may reduce dyspnea (3)

Reversal of hypoxemia

Reduced PA pressure, dynamic hyperinflation and ventilatory muscle fatigue

Stimulation of facial, nasal, or pharyngeal receptors

Increased capacity for exercise training

Placebo effect

300

90 day mortality rate for cancer related hypercalcemia

75%

300

Opioid that is least associated with respiratory depression

Buprenorphine

Partial mu agonist: It has a ceiling effect on respiratory depression

400

Management bowel obstruction when surgery is not an option (3)

Analgesics, Octreotide, anticholinergics, GI decompression,  glucocorticoids, antiemetics (haldol)

400

Mechanisms by which opioids may reduce dyspnea (3)

Analgesia - reduce pain-induced respiratory drive

Anxiolytic effects

Vasodilation (improved cardiac function, decreasing preload)

Decreased metabolic and ventilatory requirements

Reduced medullary sensitivity and response to hypercarbia or hypoxia

Blunted afferent transmission from pulmonary mechanoreceptor to the CNS

Alteration of neurotransmission within medullary respiratory center

Cortical sedation (suppression of respiratory awareness)

400

Minimal performing status to tolerate chemotherapy

ECOG PS 2

0: Fully active. 1: Ambulatory light work. 2: Self-care, Up >50% of waking hrs 3: Bed or chair>50% of waking hrs 4: Completely disabled; confined to bed or chair.
