Air caloric testing. Medical search. Frequent questions

Well your question already encapsulates one of the key reasons why one might need to perform all four irrigations (binaural & bithermal) i.e. that while mono-thermal screening reduces test time and predicts the bithermal result with high sensitivity and specificity but with certain criteria attached (e.g. the absence of spontaneous nystagmus and overall response size above a certain threshold). (interacoustics.com)
Significant findings were a severe spontaneous and constant true-whirling vertigo which worsened with head movement, horizontal-torsional spontaneous nystagmus, abnormal caloric test, positive bedside head impulse tests, and inability to tolerate head-thrust test. (springer.com)
Purpose: to compare the nystagmus response in air (50°C/24°C) and water (44°C/30°C) caloric tests. (unifesp.br)
Results: Comparing air and water caloric tests, no significant difference was found among the values of slow-phase velocity post-caloric nystagmus regarding the stimulation order, between ears and between the values of unilateral weakness and directional preponderance. (unifesp.br)
Conclusion: In air (50°C/24°C) and water (44°C/30°C) caloric tests, the post-caloric nystagmus is similar in terms of slow-phase velocity values in both ears, higher responses in the cold temperature, unilateral weakness and directional preponderance results but it is different with regard to slow-phase velocity values which are higher in water test.
