Abstract

Objective

The primary objective of this study was to evaluate the impact of high-flow nasal cannula oxygen therapy [HFNC] on the diaphragm thickening fraction.

Design

Prospective, descriptive, cohort study

Setting

The study was conducted in the Physiology and Respiratory Care Laboratory, Intensive Care Unit, Hospital Británico de Buenos Aires.

Participants

Thirteen healthy subjects >18 years old

Interventions

High-flow nasal cannula oxygen therapy

Main variables of interest

Demographic data (age and gender), anthropometric data (weight, height, and body mass index), and clinical and respiratory variables (Diaphragm thickening fraction [DTf], esophageal pressure swing, respiratory rate [RR], esophageal pressure-time product per minute [PTPes/min]).

Results

Median DTf decreased significantly as flow increased (P < .05). The baseline DTf measurement was 21.4%, 18.3% with 20 l/m, and 16.4% with 40 l/m. We also observed a significant decrease in RR as flow increased in HFNC (P < .05). In the 8 subjects with recordings, the PTPes/min was 81.3 cmH₂O/sec/min (±30.8) and 64.4 cmH₂O/sec/min (±25.3) at baseline and 40 l/m respectively (P = .044).

Conclusions

The use of high-flow oxygen therapy through nasal cannula of HFNC in healthy subjects decreases the DTf and RR in association with increased flow. In addition, the use of 40 l/m flow may reduce the muscular work associated with respiration.

通过高速气体充气进行高流量氧疗对健康受试者膈肌增厚率的影响。

目的本研究的主要目的是评估高流量鼻插管供氧疗法 [HFNC] 对横膈膜增厚分数的影响。设计前瞻性、描述性、队列研究环境本研究在布宜诺斯艾利斯不列颠医院重症监护室的生理学和呼吸护理实验室进行。参与者13名健康受试者>18岁干预措施高流量鼻插管供氧疗法主要关注变量人口统计学数据（年龄和性别）、人体测量数据（体重、身高和体重指数）以及临床和呼吸变量（膈肌增厚分数[DTf]、食管压力摆动、呼吸频率[RR]、每分钟食管压力-时间乘积[PTPes/min]）。结果随着流量的增加，中位 DTf 显著下降（P <.05）。基线 DTf 测量值为 21.4%，20 升/米时为 18.3%，40 升/米时为 16.4%。我们还观察到，随着 HFNC 流量的增加，RR 明显下降（P < .05）。在 8 名有记录的受试者中，基线和 40 l/m 时的 PTPes/min 分别为 81.3 cmH2O/sec/min（±30.8）和 64.4 cmH2O/sec/min（±25.3）（P = .044）。此外，使用 40 升/米的流量可减少与呼吸有关的肌肉工作。
