Role of stress in the development of the hyperventilation syndrome.

The occurrence of the hyperventilation syndrome (HVS) has often been associated with stress. In this experiment with normal subjects responses of PACO2, respiration rate, heart rate and checklist measures were registered in a stressful, real-life situation, namely waiting for an examination. Heart rate and one checklist measure showed a significant arousal response. There was a small but significant decrease in PACO2 from a precontrol session to the stress session, but PACO2 had not returned to base level on a postcontrol session. Respiration rate did not change at all. Similar results in other experiments led to the conclusion that stress brings about only a mild degree of hyperventilation in normal subjects. The discrepancy with results found in HSV patients has been discussed.

Synchronization of respiration.

In order to study synchronization of respiration, three different videofragments were presented to 21 normal subjects. Each fragment showed a 'therapeutic interview' specially performed for this purpose, with a 'patient' breathing in a particular way. The respiration of model 1 was deep, slow and clearly audible, the pattern of model 2 was rapid, superficial and slightly audible and that of model 3 was normal and hardly perceptible. The fragments were presented in three different sequences and each sequence was followed by seven subjects. Respiration amplitude (Vt), respiration irregularity (SD of Vt), respiration frequency (RF) and frequency of skin conductance responses (SCRF) were measured. Changes in mean values of these variables were demonstrated during the fragments; an increase in RF was the most pronounced and reliable change. These 'overall' physiological changes did not support the synchronization hypothesis, nor were they at variance with it: they seemed to be effects of attention. A detailed (cycle by cycle) analysis did reveal a synchronization effect in fragment 1. The number of cycles in the subject which were in rhythm with the model's respiration was significantly larger than could have been expected by chance. The effect of synchronization, however, was small and transient as it did not affect the mean RF and Vt of fragment 1.

Qualitative needs assessment prior to a continuing education program.

The usefulness of qualitative research is illustrated by the presentation of a needs assessment among Dutch surgical cancer nurses and patients. Participant observations and qualitative interviews showed that nurses usually did not assess pain systematically, gave insufficient pain medication, were unaware of the effectiveness of some nonpharmacological techniques, and often felt powerless in giving psychosocial support. Patients appeared inhibited in expressing pain and inhibition was reinforced by ineffective interactions with nurses. using these findings, a continuing education program on pain assessment and management was developed.
