Why the study?
Does immersion of the hand in ice-cold water increase intra-arterial pressure in healthy young adults?
Does immersion of the hand in ice-cold water increase intra-arterial pressure in healthy young adults?
Immersion of the hand in ice-cold water causes a significant elevation in both systolic and diastolic intra-arterial pressure in healthy young adults.
Supports BP elevation with cold hand immersion in healthy adults; leaves open standardization between direct and indirect measurements.
The response of the intra-arterial pressure to the cold immersion stimulus was studied in 42 healthy young adults, continuous direct (arterial-pressure) recording being used. The average systolic elevation was 22.6 mm. Hg and the average diastolic elevation was 16.3 mm. Hg. The difference between direct and indirect methods of measuring blood pressure was studied in 351 simultaneous determinations in 35 of these young adults. The direct systolic pressure averaged 9.7 mm. Hg higher and the diastolic pressure was 7.3 mm. Hg lower than the indirect measurement.
