Impute PaO2 with SpO2

Source: R/respiration.r
impute_pao2.Rd

If PaO2 is missing replace with PaO2 calculated from SpO2.

Usage

impute_pao2(pao2, spo2)

Arguments

pao2

Arterial oxygen pressure (kPa)

spo2

Peripheral oxygen saturation (%)

Value

pao2

Details

PaO2 is missing in many cases, as arterial blood gass analysis is only performed when needed. To fill those gaps, this function converts SpO2 (%) to PaO2 (kPa) in case the PaO2 is missing in the dataset. If SpO2 is >=97%, the PaO2 is set to 14.7 kPa, because the oxygen dissociation curve is not valid to use in this range. This functions uses spo2_to_pao2().
