Q

Potassium-sparing diuretics

A

Increase diuresis without causing potassium to leave the body by stopping entry of aldosterone
into the nephron preventing sodium and water retention

Q

Left sided heart failure

A

Left side is unable to pump blood from pulmonary vessels resulting in a backup of blood behind left ventricle causing increased pressure in the left atrium and pulmonary veins
As veins become enlarged with blood, serum is forced from pulmonary capillaries and into the alveoli (acute cardiogenic pulmonary edema)
Left ventricle is most commonly damaged during MI or chronic HTN

Q

Nitrates

A

Oldest class of drugs to treat angina
Dilates blood vessels and increase O2 supply to the heart by relaxing and dilating medium-large
coronary arteries and veins and reduces fluid backup in ventricles to reduce cardiac workload

Q

Monitoring CPR quality with ETCO2

A

Lower ETCO2: change compressions or improve CPR quality
ETCO2 decreasing observe for chest compressor fatigue, hyperventilation, airway obstruction, or tracheal tube displacement
ETCO2 increasing: CPR is likely effective and ventilation appropriate; substantial rise can indicate ROSC

Q

What do ETCO2 values indicate about a ROSC

If the numbers rise into 20-30s the prognosis of the ROSC are high
If the numbers rise to extreme highs a ROSC is present so check rhythm and pulse at next rhythm check
