Nitric oxide (NO) 400 ppm mol/ mol.

Nitric oxide is absorbed systemically after inhalation.

Nitric oxide is a compound produced by many cells of the body.

Nitric oxide chemically reacts with oxygen to form nitrogen dioxide.

Nitric oxide has an unpaired electron, which makes the molecule reactive.

Nitric oxide is delivered to the patient via mechanical ventilation after dilution with an oxygen/ air mixture using an approved (CE-marked) nitric oxide delivery system.

Nitric oxide then activates the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), producing smooth muscle relaxation in the corpus cavernosum and allowing inflow of blood.

»Nitrogen oxides« means nitric oxide and nitrogen dioxide, expressed as nitrogen dioxide (NO(2));

whereas, the first step towards the attainment of this objective having already been taken by the definition of certain methods in Commission Directive 80/1335/EEC (3), the second step is to consist in the definition of methods for identification of some oxidizing agents and determination of hydrogen peroxide in cosmetic hair-care products, identification and semi-quantitative determination of certain oxidation colorants in hair dyes, identification and determination of nitrite, identification and determination of free formaldehyde, determination of resorcinol in shampoos and hair lotions, and determination of methanol in relation to ethanol or propan-2-ol;

Such stations may also measure concentrations of nitric oxide.

The gases contained in the bag shall pass through a converter which reduces the nitrogen dioxide (NO2) to nitric oxide (NO).

The nitric oxide (NO) content of the gases emerging from the converter shall be determined by means of a chemiluminescence analyser.

Nitric nitrogen Water-soluble magnesium oxide

Total nitrogen Nitric nitrogen Calcium oxide soluble in water

The manganese is oxidised by sodium bismuthate in a nitric acid medium.

Whereas it is necessary to establish measuring stations to monitor compliance with the limit value for nitrogen dioxide and whereas it is desirable that these stations also measure nitric oxide which is an intermediary step in the formation of nitrogen dioxide;

O 2 uptake due to C oxidation = total observed uptake - uptake due to nitrification

Nitrogen expressed as nitric nitrogen 14 % MgO Magnesium expressed as water-soluble magnesium oxide

Nitrogen expressed as nitric nitrogen 9 % MgO Magnesium expressed as water-soluble magnesium oxide Minimum pH:

From equation (1), the oxygen uptake by 28 g of nitrogen contained in ammonium chloride (NH 4 C1) in being oxidised to nitrite is 96 g, i.e. a factor of 3,43 (96/28).

Alternatively, if only total oxidized N is determined, the oxygen uptake due to nitrification may be taken to be, as a first approximation, 4,57 increase in oxidised N.

Errors due to not considering nitrification in the assessment by oxygen uptake of the biodegradability of test substances not containing N are marginal (not greater than 5 %), even if oxidation of the ammonium-N in the medium occurs erratically as between test and blank vessels.

If nitrification has occurred but is not complete the observed oxygen uptake by the reaction mixture may be corrected for the amount of oxygen used in oxidising ammonium to nitrite and nitrate, if the changes in concentration during incubation of nitrite and nitrate are determined by consideration of the following equations:

INOmax contains nitric oxide 400 ppm mol/ mol.

BH4 is a cofactor for nitric oxide synthetase.

The active substance in INOmax is nitric oxide.

INOmax 400 ppm mol/ mol inhalation gas Nitric oxide.

When inhaled, nitric oxide produces pulmonary vasodilation.

The pharmacokinetics of nitric oxide has been studied in adults.

The nitric oxide delivery system for intermittent flow ventilation should be adequate to avoid spikes in nitric oxide concentration.

Weaning from inhaled nitric oxide should be performed with caution.

- your baby may be given nitric oxide to improve blood oxygenation.

NO2 rapidly forms in gas mixtures containing nitric oxide and O2, and nitric oxide may in this way cause airway inflammation and damage.

Repeat dose studies show that rodents can survive nitric oxide exposures until sustained levels approaching 250 ppm nitric oxide are achieved.

A large portion of nitric oxide for inhalation is absorbed systemically.

There are a range of compositions that can be denoted as MONi or MONij, where i and j are integers representing the percentage of Nitric Oxide in the mixture (e.g., MON3 contains 3 % Nitric Oxide, MON25 25 % Nitric Oxide.

There are no adequate data from the use of nitric oxide in pregnant women.

Tests show that dry nitric oxide mixtures can be used with most materials.

Nitrate has been identified as the predominant nitric oxide metabolite excreted in the urine, accounting for > 70 % of the nitric oxide dose inhaled.

- Setting the device for the correct concentration of nitric oxide to be administered

From studies in dogs it can be deduced that the lethal concentration is around 640 ppm nitric oxide for 4 hours, whereas, exposures of 320 ppm nitric oxide are non-lethal.

The concentration of carbon monoxide and nitric oxide are measured in the dry exhaust.

At levels of 80 ppm there were ‘ no observable’ effects from nitric oxide exposure.

• When nitric oxide and oxygen combine, they form a chemical called nitrogen dioxide.

Data further suggested a lack of additional benefit for the higher dose of nitric oxide.

Methaemoglobin concentrations increase during the first 8 hours of nitric oxide exposure.

The physician should have access at the bedside to a reserve nitric oxide delivery system.

7 chemical reactivity of nitric oxide in tissue is unknown. Studies show that nitric oxide exhibits pulmonary pharmacodynamic effects at intra-airway concentrations as low as 1 ppm.

Passive exposure to nitric oxide in humans during pregnancy and lactation should be avoided.

Furthermore, although both nitric oxide and the presence of nitrogen dioxide at high nitric oxide concentrations may cause tissue damage, the long-term clinical significance is unknown.
