Q

what happens to the mix venous blood of cyanide poisoning

A

it is elevated

101
Q

why dose cyanide cause a mix venous to have a higher amount of o2

A

because it displaces o2 from the hemoglobin

102
Q

if cyanide displaces o2 from hemoglobin, what else is elevated other than mix venous o2

A

partial pressure of o2 in blood

103
Q

what is the best and easiest way to check for toxicity by cyanide

A

check blood ph it will show metabolic acidosis

104
Q

what is a drug that can help with cyanide toxicity

A

thiosulfate, vitamin b12

105
Q

how dose thiosulfate work

A

it increases renal elimination of cyanide

106
Q

how does cyanide work to cause metabolic aciosis

A

it binds cytochrome oxidases and thus, prevents aerobic metabolism

107
Q

how does vitamin b12 prevent cyanide toxicitiy

A

it chelates cyanide

108
Q

what poison can be used to treat cyanide toxicity

A

methhemoglobin

109
Q

what is the byproduct if methemoglobin is used for cyanide toxicity

A

cyanmethhemoglobin

110
Q

what drugs can produce methemoglobin

A

amyl nitrite and sodium nitrite

111
Q

what is the risk of using thiosulfate for cyanide toxicity

A

thiosulfate has sulfar that pushes cyanide to metabolize into a renal excreted metabolite…thiocyanide…this in itself is toxic

112
Q

which patients should not use thiosulfate to treat cyanide toxicity

A

renal patients bc the thiocyanide that is produced cannot be excreted

113
Q

what are the symptoms of thiocyanide toxicity

A

tinnitus, visual changes, seizures

117
Q

what does milrinone do moa

A

it is a phosphodiesterase inhibitor

118
Q

what happens when you inhibit phosphodiesterase

A

it increases cAMP
