Why would a patient need to be in prone position?

1 answer:

5 0

Reduced stroke volume and cardiac index results in a drop in blood pressure often seen when a patient is turned from supine to prone. Respiratory changes include a 30% to 35% decrease in respiratory compliance and increase in peak airway pressure. This in turn decreases venous return and cardiac output.

What is the lewis structure and formal charge of CH2O

aksik [14]

Diagram A shows the Lewis structure (LS) of CH_2O. The formal charge on each atom is zero.

To get the formal charge (FC) on the atoms, cut each bond in half, as in Diagram B. Each atom gets the electrons on its side of the cut.

Formal charge = valence electrons in isolated atom - electrons on bonded atom

FC = VE - BE

On O:

VE = 6

BE = 2 lone pairs 2 + 2 bonding electrons = 4 + 2 = 6

FC = 6 – 6 = 0.

On H:

VE = 1

BE = 1 bonding electron

FC = 1 – 1 = 0

On C:

VE = 4

BE = 1 in each single bond + 2 in the double bond = 2 + 2 = 4

FC = 4 - 4 = 0
