A neonatal incubator, comprising: - a housing defining an interior to house a neonate; - a gas sampler configured to obtain one or more samples of gas from the interior of the housing; - a gas analyzer in at least indirect gaseous communication with the gas sampler and configured to analyze one or more types of biomolecules in the one or more samples of gas that are carried in a neonate's breath, feces, skin and/or urine and provide one or more signals of one or more health indicators associated with the neonate, relating to diseases or health issues, based on the analysis, wherein the gas analyzer is configured to provide data usable to render a user interface to provide output indicative of the one or more health indicators, characterized in that the biomolecules comprise one or more of: acetone; acetaldehyde; octadecane; nitrogen-containing VOCs;sulfur-containing VOCs; ethers; straight chain alkenes;branched chain alkanes; alkynes and/or non-cyclic alkenes; benzyl and phenyl hydrocarbons; non-aromatic cyclic hydrocarbons; alcohol volatiles; aldehyde volatiles; primary aliphatic acid volatiles; branched aliphatic acid volatiles; unsaturated acid volatiles; carboxylic acid volatiles; acetic acid esters; straight chain aliphatic acid esters; branched and cyclic aliphatic acetic acid esters; aromatic carboxylic acid esters; cyclic esters; non-cyclic alkenes; straight chain aliphatic ketones; branched chain and cyclic aliphatic ketones; di-ketones; unsaturated ketones; halogen containing VOCs; and further characterized in that the neonatal incubator comprises - a reliability indicator operably coupled with the gas analyzer and configured to provide, to the gas analyzer, based on a state of isolation between the interior of the housing and an exterior environment, a signal indicative of reliability of the one or more samples of gas. - a housing defining an interior to house a neonate; - a gas sampler configured to obtain one or more samples of gas from the interior of the housing; - a gas analyzer in at least indirect gaseous communication with the gas sampler and configured to analyze one or more types of biomolecules in the one or more samples of gas that are carried in a neonate's breath, feces, skin and/or urine and provide one or more signals of one or more health indicators associated with the neonate, relating to diseases or health issues, based on the analysis, wherein the gas analyzer is configured to provide data usable to render a user interface to provide output indicative of the one or more health indicators, characterized in that the biomolecules comprise one or more of: acetone; acetaldehyde; octadecane; nitrogen-containing VOCs;sulfur-containing VOCs; ethers; straight chain alkenes;branched chain alkanes; alkynes and/or non-cyclic alkenes; benzyl and phenyl hydrocarbons; non-aromatic cyclic hydrocarbons; alcohol volatiles; aldehyde volatiles; primary aliphatic acid volatiles; branched aliphatic acid volatiles; unsaturated acid volatiles; carboxylic acid volatiles; acetic acid esters; straight chain aliphatic acid esters; branched and cyclic aliphatic acetic acid esters; aromatic carboxylic acid esters; cyclic esters; non-cyclic alkenes; straight chain aliphatic ketones; branched chain and cyclic aliphatic ketones; di-ketones; unsaturated ketones; halogen containing VOCs; and further characterized in that the neonatal incubator comprises wherein the gas analyzer is configured to provide data usable to render a user interface to provide output indicative of the one or more health indicators, characterized in that the biomolecules comprise one or more of: acetone; acetaldehyde; octadecane; nitrogen-containing VOCs;sulfur-containing VOCs; ethers; straight chain alkenes;branched chain alkanes; alkynes and/or non-cyclic alkenes; benzyl and phenyl hydrocarbons; non-aromatic cyclic hydrocarbons; alcohol volatiles; aldehyde volatiles; primary aliphatic acid volatiles; branched aliphatic acid volatiles; unsaturated acid volatiles; carboxylic acid volatiles; acetic acid esters; straight chain aliphatic acid esters; branched and cyclic aliphatic acetic acid esters; aromatic carboxylic acid esters; cyclic esters; non-cyclic alkenes; straight chain aliphatic ketones; branched chain and cyclic aliphatic ketones; di-ketones; unsaturated ketones; halogen containing VOCs; and further characterized in that the neonatal incubator comprises - a reliability indicator operably coupled with the gas analyzer and configured to provide, to the gas analyzer, based on a state of isolation between the interior of the housing and an exterior environment, a signal indicative of reliability of the one or more samples of gas.
