Furthermore, it was alarming for us to discover the high use of second generation macrolides and cephalosporins rather than the recommended narrower spectrum agents.
Science
Regarding those patients who required ICU support, the likelihood that recommended broad spectrum empiric antibiotics were received in the ED increased over time.
We assessed the impact of an extended-spectrum antibiotic prophylaxis regimen (azithromycin in addition to recommended narrow-spectrum cephalosporin) on postcesarean incisional wound infection.
Third, even when the Gram-stain results recommended narrow-spectrum antimicrobials, staff members were trained to commence empirical broad-spectrum antimicrobials if the patient was in a critical condition or at risk of multidrug-resistant bacterial infection.

The panel recommends making spectrum sharing part of the policy for managing spectrum.
News & Media
Unfortunately only for pneumonia a fair number of epidemiological studies were found allowing a very good description of the microbiological profile involved, which is the only HCAI for which specific treatment recommendations are available [ 13] and they recommend broad spectrum antibiotics with an empiric coverage of Pseudomonas spp. and MRSA.
Science
If the background rates contributing to a source are significantly different in the individual spectra to be combined, it is recommended that these spectra remain separate and be modeled simultaneously - otherwise, the modeling results of the combined source spectrum could be biased towards the observation(s) with the highest background rate(s).

My Apr. 10 column recommended a wide spectrum of North American energy investments: natural gas, coal, offshore drilling, nuclear and Canadian tar sands.

For non-symmetrical buildings, the ECP-201 (ECP 2008) recommended the response spectrum method to be used for building seismic analysis and design, which considered more accurate method of analysis than the ESL method (Chopra 1995; Paz and Leigh 2003).
For nonsymmetrical buildings, ECP (2008) recommended the response spectrum method to be used for building seismic analysis and design, which was considered to be a more accurate method of analysis than the equivalent static load method (Chopra 1995; Paz and Leigh 2003).
Expert writing Tips
Best practice
When discussing technical specifications, ensure that the "recommended spectrum" is clearly defined with specific numerical values and units to avoid ambiguity.
Common error
Avoid using "recommended spectrum" when you simply mean a general "range" of options or ideas. "Spectrum" implies a continuous distribution across frequencies or wavelengths, whereas "range" can refer to any set of values.

Ludwig's WRAP-UP
The phrase "recommended spectrum" is a noun phrase generally used in technical or scientific domains to advise on or specify an ideal range of frequencies or wavelengths. While the phrase itself is grammatically correct, as noted by Ludwig, it currently shows a lack of real-world examples, which suggests it may be a niche term or that its occurrences are spread across diverse sources not easily aggregated. When using this phrase, clarity is key; provide specific numerical values and units. Alternatives such as "suggested bandwidth" or "advised frequency range" may be more appropriate depending on the context. Due to its limited presence in the analyzed data, understanding the subtleties of its usage in specific domains becomes particularly important.

FAQs
How can I use "recommended spectrum" in a sentence?
You can use "recommended spectrum" in sentences such as: "The device operates within the "recommended spectrum" for optimal performance" or "The guidelines specify the "recommended spectrum" to minimize interference."
What is the difference between "recommended spectrum" and "suggested bandwidth"?
"Recommended spectrum" refers to the overall range of frequencies or wavelengths that are advised, while "suggested bandwidth" specifically refers to the range of frequencies used for data transmission.
Which is more appropriate, "recommended spectrum" or "optimal frequency range"?
Both "recommended spectrum" and "optimal frequency range" can be appropriate depending on the context. "Recommended spectrum" implies an officially advised range, while "optimal frequency range" suggests the best range for a particular application.
